Prior to Installation
- Be sure to test your existing system and check that the heating and/or cooling functions normally before disconnecting any wires.
- When testing, do not select COOL mode if the outside temperature is below 50°F (10°C), as this could damage the cooling system.
- If you have a heat pump system, check the settings on your old thermostat and make a note of whether you have an “O” or “B” type reversing valve.
Removing the Old Thermostat
1. Turn the power to your HVAC system OFF at the breaker box or the main switch controlling your heating/cooling system.
2. Confirm that the power is OFF by adjusting the temperature on your old thermostat and ensure your system doesn’t turn on.
3. Carefully remove the faceplate of your old thermostat.
4. Take a picture of your old thermostat’s wire arrangement to reference later on.
5. Make note of the current locations of each colored wire by referencing the Wiring Chart below.
Note: If you see any A, X, or P wires, please contact us to check system compatibility at 888.313.7019
6. Make sure you don’t have any 120/240V wires (look for thick black wires with wire nuts.) If you do, the iDevices Thermostat is not compatible with your system. If you are unsure, call us at 888.313.7019.
7. Record the locations of any jumpers and note whether there is a wire connected to RC and/or RH.
8. Lastly, disconnect the wires from the old thermostat and remove it from the wall.
Tip: Ensure the wires don’t fall back into the wall by gently wrapping them around a pen.
Installing the New Thermostat
1. Line up the iDevices Thermostat mounting plate on the wall. Check that it is level and the wires are able to fit through the hole on the mounting plate. Use a pencil to mark the wall anchor locations on the wall.
2. Set the mounting plate aside and drill two holes (3/16” diameter) where you just marked.
3. Install the provided wall anchors, line up the mounting plate to the holes and using the provided screws, attach the mounting plate to the wall.
4. In the installation guide, head over to the Wiring Configuration section and find the wiring that is closest to your old thermostat. Note which system you have to reference later. To view the Wiring Configurations online, Click Here
5. Connect the wires to the mounting plate according to the wiring chart above, photos you took earlier, and the wiring configuration you noted for step 4.
Note: To prevent electrical shorts and damage to your new Thermostat or home, ensure all of the wire connections are secure and that bare wires are not touching each other. Insulate any bare wires with electrical tape as necessary.
6. Push any excess wires back into the wall cavity and attach your iDevices Thermostat to the mounting plate.
7. Turn the power back on at the breaker box or switch that controls your heating/cooling system.
Note: After changing modes, there is a standard 5-7 minute delay before the Thermostat will call for heating or cooling to protect the compressor for air conditioners and heat pump systems. During this delay, the temperature setpoint on the Thermostat display will show in black. Once the 5-7 minute delay has passed and the Thermostat calls for heating or cooling, the temperature setpoint will then show in red for heating and blue for cooling.
