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 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.
The jumper wire can easily be replaced connecting it to the "R" and "RC" terminals on your thermostat wallplate. If you are unable to find the factory installed jumper, a short piece of wire can be used in its place. Please refer to step 1.7 in the Quick Start Guide.
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.
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 or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.
A small flat edge pocket screwdriver and a No. 2 Phillips screwdriver are recommended.
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.
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.
Yes - the C wire is necessary because it provides power to your new thermostat.
