Often, the thermostat will separate from the wallplate with moderate pressure. Other times, there might be small screws holding the device in place. If you are unable to pull it off, please refer to your thermostat manufacturer's website or manual for removal instructions. NOTE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact the Thermostat Recycling Corporation at http://www.thermostat-recycle.org/ or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.
An extra unused wire in the wall can be used as the C wire for your new thermostat. The extra wire will also need to be connected to the C (common) terminal at the heating and cooling system. This will provide power to your new thermostat. Please refer to the video section for more information.
In most cases, the only tools and materials required are a small flat edge screwdriver, #2 phillips screwdriver, your thermostat ID card (located in the box), and your home Wi-Fi Network password.
The thermostat will have a glass tube with a silver liquid inside of the tube. Mercury is typically found in older mechanical thermostats like the Honeywell Round T87 and rectangular T8090.
NOTE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact the Thermostat Recycling Corporation at http://www.thermostat-recycle.org/ or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.
The C wire originates from your heating/cooling system and provides 24 volt power to your Lyric. "C" stands for common and there is no universal color used to designate this type of wire. If you do not have a C wire, your Lyric will instead draw power from your heating and cooling systems to power its battery.
There is no code governing wire colors and thermostat connections. The thermostat should be wired by the letters found next to the wire screw terminal block. If you do not know the letter labels, then you can trace the wires back to the air handler/furnace or heat pump/ac unit. That will allow you to determine the function of each wire at the system and then allow you to attach it to the matching terminal on the thermostat.
If you do not have a wire connected to a C terminal or one that is labeled C on your old thermostat, there might be an extra wire that is pushed into the wall or wrapped around the wire bundle coming from the wall. Gently pull on the wire bundle to check whether there are any additional wires. If you do not have any additional wires, please refer to the Install Videos for alternative wiring.
Honeywell offers several resources to assist in the wiring of your new thermostat. These resources include: Installation videos, a User Guide and a Quick Start Guide. If you are still unsure if your new thermostat is wired correctly, please contact Honeywell Customer Care at 1-855-733-5465.
A COM terminal is often used as another name for the C terminal and issued to provide power to your thermostat. COM can also refer to a communication circuit and will not provide power to the thermostat. If you have both a C and COM terminal on your heating and cooling system the thermostat should be wired to the C terminal. Please refer to the Quick Start Guide for more information.
Check the back or bottom of the router or the operating manual for the password. If you are still unable to find the password contact the router manufacturer.
