Setup
The thermostat will automatically detect connected wires. Follow the on-screen instructions to complete the thermostat configuration.
Note: If the thermostat screen does not show all the connected wires, remove the thermostat from the wall and verify that all wires are properly connected. If issues persist, there may be a problem with automatically detecting your wiring.
Depending on the system type and configuration, the thermostat may request the following information during setup:
Heat type
Tells the thermostat whether it should turn on the fan during a heating cycle.
- Forced air heating: Electric
- Radiant floor heating: Fossil
- Fossil/electric baseboard heating: Fossil
- Radiators: Fossil
- If unsure: Unsure
Backup heat type
Tells the thermostat what type of auxiliary/ backup heating the heat pump uses.
- Electric: This is the most common type of backup heating.
- Dual fuel: Some heat pumps use a fossil furnace (e.g., natural gas, oil, or propane) for backup heating.
- If unsure: The system will automatically detect which heat type is appropriate for your system.
Z1/Z2 terminal function
These are the “dynamic” terminals. If an auxiliary wire has been connected, please specify the function it will perform.
- W3: Third stage of heat or aux
