FREQUENTLY ASKED QUESTIONS

Push the up or down arrow buttons on the thermostat to check the temperature that the thermostat has been set to.
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.

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 72 to avoid jumping up and down constantly.

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.
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
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.
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.
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.
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.
