What to check if my Wiser Air thermostat will not power on after installation.
Product Line: Wiser Air thermostat Resolution:
Check your load center to confirm that your HVAC breakers are turned on and not in the off or tripped positions.
Wiser Air requires a 24 VAC and common from the heating or cooling system control board. If your previous thermostat did not have a common wire connected to the C terminal or any extra wires present, the wire extender will need to be installed. Please see the Wiser Air Installation Guide below for further help.
***Note: Be sure to not power the thermostat directly to 120/240 Vac.
