Connecting the Thermostat Control to Equipment Interface

Only four wires are needed to connect the Thermostat to the Equipment Interface. If you are replacing a Thermostat, you can use the existing wiring.

Note: Ensure any unused wires do not have exposed bare copper conductors.

1.  Connect the wires between the Thermostat and Equipment Interface as shown below.


2.  Attach the front cover of the Smart Thermostat to the backplate. Ensure the four pins on the circuit board mate with the terminal block on the backplate as shown below.


The Thermostat comes with a factory installed, coin cell battery. When replacing the battery ensure the + side of the battery is facing out and the battery contacts remain in the upright position (not bent underneath the battery). The battery should snap in easily.
