How do I determine whether the thermostat is calling for second stage of heating or cooling?
Answer: Press "Menu: followed by "Equipment Status". This shows the status of the heating and the cooling equipment and the number of stages engaged.
How do I find my Thermostat model number?
Answer: Honeywell thermostats have a model number that begins with a TH, T, RTH, CT, TL or RLV. The location of the model number varies depending upon the thermostat.
If the thermostat is battery operated and the batteries are accessed from the front of the thermostat, please check the area around the batteries. If the batteries are on the back of the thermostat or if the thermostat is not battery operated, the model number should be on the back of the thermostat once the thermostat is removed from its base. If your thermostat has a mechanical clock, the model number is on a sticker on the horizontal surface above the clock.
How does the FAN Auto/On switch or key work?
Answer: The FAN selection key has two or three positions: Auto and On and sometimes Circ (Circulate). The Auto position will allow the system fan to operate whenever the heating or cooling system is turned on by the thermostat. The On position will turn the fan on to run continuously, regardless whether heating or cooling system is turned on by the thermostat or not. The Circ (Circulate) position if available will run the fan approximately 35% of the time, minus any time the fan will run with the heating or cooling system.
How does the Portable Comfort Control work?
Answer: The Portable Comfort Control allows you to control the system status (i.e. heat off or cool and the temperature settings for thermostat). If only one thermostat is connected, then you can control the temperature from the location of the handheld or the thermostat. If more than one thermostat is connected, then you can toggle between different zones of the house.
How many thermostats can one Portable Comfort Control manage?
Answer: One Portable Comfort Control can manage up to 16 thermostats.
I am unsure of the voltage coming up to my thermostat. How do I find out?
Answer: Honeywell offers thermostats for both low voltage (24 volts) and line voltage (120 or 240 volts) systems. The most common type of voltage from a central heating and/or cooling system is 24 volts (24Vac). The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac).
If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system. You will need a line voltage thermostat. This type of voltage is common with electric baseboard heating.
Regardless of the voltage, Honeywell strongly suggests that you turn off the power to the system at the furnace, at the fuse, or at the circuit breaker panel before installing or replacing a thermostat. If you are unsure about your voltage, please contact a local heating and cooling contractor in your area for assistance.
Is it possible to see outside temperature and humidity on my thermostat?
Answer: Yes. When connected with an Outdoor Sensor, select thermostats and devices will display the outdoor temperature and humidity on the screen.
Is the packaging for this thermostat recyclable?
Answer: Yes, the packaging contained with the thermostat is recyclable. Information about recycling thermostats containing mercury can be found at: thermostat-recycle.org/
My system turns on and off too fast. What should I do?
Answer: Your thermostat is designed to control temperature to +/- 1 F. How often your heat turns on and off depends on may factors including the type of heating system you have, as well as how much your system needs to run to maintain your temperature setting (in other words, how cool or cold it is outside). A typical forced air system will cycle about five times in an hour (5CPH), this is normal. A typical hot water system would cycle less then that
My thermostat shows humidity however I am unable to change it.
Answer: If the VisionPRO Thermostat does not allow you to change the humidity settings, then it is not setup for dehumidification or humidification control. In this case Honeywell recommends speaking to the installing contractor of the thermostat.
On my Heat Pump Thermostat, my backup heat turns on when I move the temperature higher. Why?
Answer: The thermostat takes the temperature override as a need to reach the new temperature setting right away. It will run the backup heat only as long as necessary to reach new temperature setting.
Stage two of heat or cool turns on right away when I move the temperature higher or lower. Why?
Answer: The thermostat takes the temperature override as a need to reach the new temperature setting right away. It will run the second or third stage only as long as necessary to reach new temperature setting.
The thermostat does not show "Auto" under "System".
Answer: "Auto" under "System" indicates that it is setup to automatically switch between heating and cooling. If your thermostat does not show auto, you may not have this feature.
What is a changeover valve on a heat pump?
Answer: The changeover valve is a device which reverses the flow of refrigerant in the heat pump. This will allow the freon to reverse and heat the home or cool the home. Honeywell uses an O terminal to energize the valve in cooling and a B terminal to energize the valve in heating. Some manufacturers of heat pumps may use the B terminal to energize in heating, while a vast majority energize the O terminal in cooling.
What is a heat pump?
Answer: A heat pump is a single system that provides both heating and cooling to the home. For example, the air conditioner may prove both heating and cooling to the home - this is called a heat pump. Often the heat pump also has some sort of backup or auxiliary heat for when it is cold outside. The backup or auxiliary heat could be electric heat strips or a fossil fuel furnace.
Thermostats that control heat pumps with backup or auxiliary heat typically have an Em Heat (Emergency heat) position. When the system switch is moved to the Em Ht. position, the auxiliary heat is activated on a call for heat. The compressor is disabled.
What is the difference between "Aux Ht" and "Em Ht"?
Answer: Aux Ht or Auxiliary heat is the backup heat that turns on to help the compressor for first stage maintain your temperature setting.
You know if the auxiliary heat is running when you see "Aux Heat On" in the thermostat's display. During this time both your Auxiliary heat and your compressor may be on at the same time.
The thermostat will only run the Emergency Heat when the thermostat’s system switch is moved to the Em Ht position. When the thermostat is in this position the compressor does not run, only the Emergency heat runs. It is common that the Emergency heat and auxiliary or backup heat is the same source of heat (electric heat strips or fossil fuel).
What is the EM HT (Emergency Heat) switch position on my heat pump thermostat?
Answer: The EM HT (Emergency Heat) feature allows the user to use a backup heat source when the heat pump is not working. The Emergency Heat feature locks out the heat pump compressor so that only backup heat is used. This is typically used until a heating and/or cooling contractor can troubleshoot or fix the heat pump system.
Why does my thermostat beep?
Answer: Honeywell thermostats do not have the capability of making an audible noise such as a beeping sound. The noise you are hearing is likely from another electronic device which is near the thermostat. Check for a smoke detector, door bell, or security system.
Why does the thermostat temperature not match my temperature thermometer in my home?
Answer: Honeywell digital thermostats are designed to display the room temperature in a way similar to how people sense temperature. This means the thermostat takes into account not just the ambient air temperature but also the radiant temperature of objects in the room (i.e., wall and furniture). Room thermometers often only read ambient air temperature so they will not match the thermostat reading. Also, Honeywell thermostats do round in the display to the nearest whole number (half number in Celsius) and to the temperature setting. For example, if you have the thermostat set to 72 degrees the system will turn on and off but the inside reading on the thermostat never changes from 72. The actual temperature did fall to 71 or up to 73 and that is what turned on the heating or cooling but the thermostat display will stay at 70 to avoid jumping up and down constantly.
Why is my cooling not working?
Answer: There are several items you can check. First check that the thermostat is set to the Cool position. Make sure the temperature is set lower than the Inside temperature reading. Also check the circuit breaker and reset if necessary. Make sure that the furnace door is closed securely. If “wait” is in the screen or “cool on” is flashing – wait 5 minutes for the system to safely respond. The thermostat will indicate it is asking for the cooling to turn on when "cool on" or a "snowflake" in the display. If this message is in the display, the thermostat is asking for the heat to be on and there is a likely a problem outside of the thermostat preventing the cooling from running.

Answer: There are several items you can check. First check that the thermostat is set to the Heat position. Make sure the temperature is set higher than the Inside temperature reading. Also check the circuit breaker and reset if necessary. Make sure that the furnace door is closed securely. If “wait” is in the screen or “heat on” is flashing – wait 5 minutes for the system to safely respond. The thermostat will indicate it is asking for the heat to turn on when "heat on" or a "flame" in the display. If this message is in the display, the thermostat is asking for the heat to be on and there is a likely a problem outside of the thermostat preventing the heat from running.
Why is my thermostat starting the heat or cool before the program time?
Answer: The thermostat has a feature called Adaptive Intelligent Recovery(AIR) or Smart Response or Early Start. This allows the thermostat to "learn" how long the heating and cooling system will take to reach the programmed temperature settings. So the temperature is reached at the time you set. For example: Set the Wake time to 6am, and the temperature to 70F. The heat will come on before 6am, so the temperature is 70F by the time you wake at 6am. The message "recovery" is displayed when the system is activated before a scheduled time period.
Why is the "Cool On", "Heat On", "Snowflake" or "flame" blinking or who is "Wait" on the thermostat display?
Answer: The thermostat has a built-in 5 minute delay to protect your equipment. If “wait” is in the screen or “cool on” is flashing – wait 5 minutes for the system to safely respond.

Answer: The Vision PRO IAQ is a hardwired thermostat and if the display of the thermostat is blank, please:
Check the circuit breaker and reset if necessary.
Make sure the power switch at heating & cooling system is on.
Make sure the furnace door is closed securely.
If these steps do not help, please contact the installing contractor of the thermostat for further assistance.

Can the backlight be turned on all of the time?
Answer: It depends, if the thermostat is powered with a 24 Vac common it can be set to have continuous backlight. If the thermostat is battery powered, it cannot be set for continuous backlight.
How do I clean the screen of the thermostat?
Answer: Press the SCREEN button to lock the screen for cleaning. The screen will remain locked for 30 seconds. After 30 seconds press Done to resume normal operation. Do not spray anything directly on the screen. Spray liquids onto a cloth, and then use the damp cloth to clean the screen. Use water or household glass cleaner. Avoid abrasive cleansers.
How do I find my Thermostat model number?
Answer: Honeywell thermostats have a model number that begins with a TH, T, RTH, CT, TL or RLV. The location of the model number varies depending upon the thermostat.
If the thermostat is battery operated and the batteries are accessed from the front of the thermostat, please check the area around the batteries. If the batteries are on the back of the thermostat or if the thermostat is not battery operated, the model number should be on the back of the thermostat once the thermostat is removed from its base. If your thermostat has a mechanical clock, the model number is on a sticker on the horizontal surface above the clock.
How does the FAN Auto/On switch or key work?
Answer: The FAN selection key has two or three positions: Auto and On and sometimes Circ (Circulate). The Auto position will allow the system fan to operate whenever the heating or cooling system is turned on by the thermostat. The On position will turn the fan on to run continuously, regardless whether heating or cooling system is turned on by the thermostat or not. The Circ (Circulate) position if available will run the fan approximately 35% of the time, minus any time the fan will run with the heating or cooling system.
I am unsure of the voltage coming up to my thermostat. How do I find out?
Answer: Honeywell offers thermostats for both low voltage (24 volts) and line voltage (120 or 240 volts) systems. The most common type of voltage from a central heating and/or cooling system is 24 volts (24Vac). The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac).
If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system. You will need a line voltage thermostat. This type of voltage is common with electric baseboard heating.
Regardless of the voltage, Honeywell strongly suggests that you turn off the power to the system at the furnace, at the fuse, or at the circuit breaker panel before installing or replacing a thermostat. If you are unsure about your voltage, please contact a local heating and cooling contractor in your area for assistance.
Is it possible to see outside temperature and humidity on my thermostat?
Answer: Yes. When connected with an Outdoor Sensor, select thermostats and devices will display the outdoor temperature and humidity on the screen.
Is the packaging for this thermostat recyclable?
Answer: Yes, the packaging contained with the thermostat is recyclable. Information about recycling thermostats containing mercury can be found at: thermostat-recycle.org/
My system turns on and off too fast. What should I do?
Answer: Your thermostat is designed to control temperature to +/- 1 F. How often your heat turns on and off depends on may factors including the type of heating system you have, as well as how much your system needs to run to maintain your temperature setting (in other words, how cool or cold it is outside). A typical forced air system will cycle about five times in an hour (5CPH), this is normal. A typical hot water system would cycle less then that
My thermostat does not show "Sched" or "Hold" buttons. Why?
Answer: If the thermostat is set for operation as a non programmable unit then it will not show Sched or Hold in the display. To check how the thermostat has been set up, please refer to the owner's manual under Advanced Functions and refer to feature 0160.
Stage two of heat or cool turns on right away when I move the temperature higher or lower. Why?
Answer: The thermostat takes the temperature override as a need to reach the new temperature setting right away. It will run the second or third stage only as long as necessary to reach new temperature setting.
The thermostat does not show "Auto" under "System".
Answer: "Auto" under "System" indicates that it is setup to automatically switch between heating and cooling. If your thermostat does not show auto, you may not have this feature.
What is a changeover valve on a heat pump?
Answer: The changeover valve is a device which reverses the flow of refrigerant in the heat pump. This will allow the freon to reverse and heat the home or cool the home. Honeywell uses an O terminal to energize the valve in cooling and a B terminal to energize the valve in heating. Some manufacturers of heat pumps may use the B terminal to energize in heating, while a vast majority energize the O terminal in cooling.
What is a heat pump?
Answer: A heat pump is a single system that provides both heating and cooling to the home. For example, the air conditioner may prove both heating and cooling to the home - this is called a heat pump. Often the heat pump also has some sort of backup or auxiliary heat for when it is cold outside. The backup or auxiliary heat could be electric heat strips or a fossil fuel furnace.
Thermostats that control heat pumps with backup or auxiliary heat typically have an Em Heat (Emergency heat) position. When the system switch is moved to the Em Ht. position, the auxiliary heat is activated on a call for heat. The compressor is disabled.
Why does my thermostat beep?
Answer: Honeywell thermostats do not have the capability of making an audible noise such as a beeping sound. The noise you are hearing is likely from another electronic device which is near the thermostat. Check for a smoke detector, door bell, or security system.
Why does the thermostat temperature not match my temperature thermometer in my home?
Answer: Honeywell digital thermostats are designed to display the room temperature in a way similar to how people sense temperature. This means the thermostat takes into account not just the ambient air temperature but also the radiant temperature of objects in the room (i.e., wall and furniture). Room thermometers often only read ambient air temperature so they will not match the thermostat reading. Also, Honeywell thermostats do round in the display to the nearest whole number (half number in Celsius) and to the temperature setting. For example, if you have the thermostat set to 72 degrees the system will turn on and off but the inside reading on the thermostat never changes from 72. The actual temperature did fall to 71 or up to 73 and that is what turned on the heating or cooling but the thermostat display will stay at 70 to avoid jumping up and down constantly.
Why is my cooling not working?
Answer: There are several items you can check. First check that the thermostat is set to the Cool position. Make sure the temperature is set lower than the Inside temperature reading. Also check the circuit breaker and reset if necessary. Make sure that the furnace door is closed securely. If “wait” is in the screen or “cool on” is flashing – wait 5 minutes for the system to safely respond. The thermostat will indicate it is asking for the cooling to turn on when "cool on" or a "snowflake" in the display. If this message is in the display, the thermostat is asking for the heat to be on and there is a likely a problem outside of the thermostat preventing the cooling from running.
Why is my heat not working?
Answer: There are several items you can check. First check that the thermostat is set to the Heat position. Make sure the temperature is set higher than the Inside temperature reading. Also check the circuit breaker and reset if necessary. Make sure that the furnace door is closed securely. If “wait” is in the screen or “heat on” is flashing – wait 5 minutes for the system to safely respond. The thermostat will indicate it is asking for the heat to turn on when "heat on" or a "flame" in the display. If this message is in the display, the thermostat is asking for the heat to be on and there is a likely a problem outside of the thermostat preventing the heat from running.
Why is my thermostat not adjusting for Daylight Saving Time?
Answer: The VisionPRO thermostats have the ability to automatically adjust for Daylight Light Saving Time. Due to unforeseen changes in 2007 to the law modifying the beginning and the end of Daylight Saving Time, thermostats that were originally released do not have the updated dates to update on the correct dates. Production changes were made as soon as possible following the law change to add the ability to automatically adjust to the new date settings. DST
We are unable to accommodate requests to trade-in an older version of the thermostats to new ones after the change in the law. In these instances, we recommend turning off the Daylight Saving Time automatic adjustment feature. This can be done in the user setup (instructions in the operating manual). Then the time should be adjusted in the fall and spring just like many other clocks in the home.
Why is my thermostat starting the heat or cool before the program time?
Answer: The thermostat has a feature called Adaptive Intelligent Recovery(AIR) or Smart Response or Early Start. This allows the thermostat to "learn" how long the heating and cooling system will take to reach the programmed temperature settings. So the temperature is reached at the time you set. For example: Set the Wake time to 6am, and the temperature to 70F. The heat will come on before 6am, so the temperature is 70F by the time you wake at 6am. The message "recovery" is displayed when the system is activated before a scheduled time period.
Why is the "Cool On", "Heat On", "Snowflake" or "flame" blinking or who is "Wait" on the thermostat display?
Answer: The thermostat has a built-in 5 minute delay to protect your equipment. If “wait” is in the screen or “cool on” is flashing – wait 5 minutes for the system to safely respond.

How do I program my TL8230 or TL8130 Thermostat?
Answer: To begin programming your thermostat, make sure that the Time and Day are correctly set. Press the “Hour” and “Min” buttons to set the Clock to the current time. Press the “Day” button to set the Day to the correct Day of the week.
• The TL8230 or the TL8130 Thermostat has three temperature presets, the Comfort preset, the Economy preset, and the Vacation preset.
• You will next need to determine at what temperatures you would like to set these presets.
• The Comfort preset is intended to be used in Programs 1 and 3, while you are at home.
• The Economy preset is intended to be used in programs 2 and 4, while you are away from the home, or asleep.
• The Vacation preset is intended to be used to override the programming during vacations or other times when you are away from home for a period of 1 or more days.
The thermostat displays the actual room temperature. To View the Set point
Tap the temperature “Up” or “Down” button to see what the current set point is. The set point will be displayed for 5 seconds
Use the up and down arrows to set the desired temperature and press and hold the “Sun” icon to set the at home temperature or press and hold the “Moon” icon to set the away from home temperature.
To Program the Thermostat:
• Press the “Pgm” button to begin setting the programs. You can set the days individually by using the “Day” button to advance to the next Day, once the program time has been set or you can set all of the days at once by holding the Day button.
• Press the “Clear” button if you wish not to have a program period and have the thermostat to skip period. Dashes will be displayed instead of a Time
• To advance to the next program period press the “Pgm” button. The “Sun” temperature corresponds with programs 1 and 3 and the “Moon” temperature corresponds with programs 2 and 4.
• Press the “Mode” button to exit and save Program times and settings.

What is a resistive load?
Answer: A resistive load is typically an electric baseboard heater. In resistive loads, the amperage remains the same throughout the call for heat. Inductive loads are typically seen in a motor load. The motor will pull a greater amount of amperage to start and then will drop significantly once the motor is running. Inductive loads require a thermostat specifically designed for inductive loads. The higher the temperature, lower the resistance.

How do I check the temperature that the thermostat has been set to?
Answer: Push the up or down arrow buttons on the thermostat to check the temperature that the thermostat has been set to.
How does the FAN Auto/On switch or key work?
Answer: The FAN selection key has two or three positions: Auto and On and sometimes Circ (Circulate). The Auto position will allow the system fan to operate whenever the heating or cooling system is turned on by the thermostat. The On position will turn the fan on to run continuously, regardless whether heating or cooling system is turned on by the thermostat or not. The Circ (Circulate) position if available will run the fan approximately 35% of the time, minus any time the fan will run with the heating or cooling system.
I am unsure of the voltage coming up to my thermostat. How do I find out?
Answer: Honeywell offers thermostats for both low voltage (24 volts) and line voltage (120 or 240 volts) systems. The most common type of voltage from a central heating and/or cooling system is 24 volts (24Vac). The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac).
If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system. You will need a line voltage thermostat. This type of voltage is common with electric baseboard heating.
Regardless of the voltage, Honeywell strongly suggests that you turn off the power to the system at the furnace, at the fuse, or at the circuit breaker panel before installing or replacing a thermostat. If you are unsure about your voltage, please contact a local heating and cooling contractor in your area for assistance.
My system turns on and off too fast. What should I do?
Answer: Your thermostat is designed to control temperature to +/- 1 F. How often your heat turns on and off depends on may factors including the type of heating system you have, as well as how much your system needs to run to maintain your temperature setting (in other words, how cool or cold it is outside). A typical forced air system will cycle about five times in an hour (5CPH), this is normal. A typical hot water system would cycle less then that
What is a cycle rate?
Answer: Your thermostat is designed to control temperature to +/- 1 F, the cycle rate setting is one factory that helps the thermostat maintain your temperature setting. How offen your heat turns on and off depends on may factors including the type of heating system you have as well as how much your system needs to run to maintain your temperature setting (in other words, how cool or cold it is outside). A typical forced air system will cycle about five times in an hour, this is normal. A typical hot water system would cycle less then that. Every heating system type will deliver heat to the house at a slightly different rate. Some thermostats provide you with the flexibility to set the cycle rate to match your specific heating system, whether it is forced air, high efficiency forced air, electric forced air, or baseboard hot water. Your thermsotat operating manual will tell you to match the cycle rate setting to your heating system type.
What is a heat pump?
Answer: A heat pump is a single system that provides both heating and cooling to the home. For example, the air conditioner may prove both heating and cooling to the home - this is called a heat pump. Often the heat pump also has some sort of backup or auxiliary heat for when it is cold outside. The backup or auxiliary heat could be electric heat strips or a fossil fuel furnace.
Thermostats that control heat pumps with backup or auxiliary heat typically have an Em Heat (Emergency heat) position. When the system switch is moved to the Em Ht. position, the auxiliary heat is activated on a call for heat. The compressor is disabled.
What replacement thermostat do you recommend for a millivolt heating system such as a fireplace?
Answer: Honeywell offers a variety of thermostats that are capable of working with 750 mV heating systems such as fireplaces. Thermostats you find at the retail store will indicate on their packaging that it will work with these type of systems. If you've already purchased a thermsotat, also check the literature for this type of system. check literature provided with the thermostat if it can accommodate heating system.
Why does my thermostat beep?
Answer: Honeywell thermostats do not have the capability of making an audible noise such as a beeping sound. The noise you are hearing is likely from another electronic device which is near the thermostat. Check for a smoke detector, door bell, or security system.
Why does the thermostat temperature not match my temperature thermometer in my home?
Answer: Honeywell digital thermostats are designed to display the room temperature in a way similar to how people sense temperature. This means the thermostat takes into account not just the ambient air temperature but also the radiant temperature of objects in the room (i.e., wall and furniture). Room thermometers often only read ambient air temperature so they will not match the thermostat reading. Also, Honeywell thermostats do round in the display to the nearest whole number (half number in Celsius) and to the temperature setting. For example, if you have the thermostat set to 72 degrees the system will turn on and off but the inside reading on the thermostat never changes from 72. The actual temperature did fall to 71 or up to 73 and that is what turned on the heating or cooling but the thermostat display will stay at 70 to avoid jumping up and down constantly.
