Why is my smart thermostat screen blank or no power?
Pleae Verify R/C Wire Connections:Check that R (Red) and C (Common) wires are securely inserted at both the thermostat and HVAC control board. The C wire must be connected to the "C" terminal at the furnace.
I have R, W, Y, G wires. Is it compatible? Do I need a C-wire adapter?
Yes, the smart WiFi thermostat is compatible; however, a C-wire adapter is required for wiring configurations including R, W, Y, G; R, O/B, Y, G; or R, O/B, Y, G, W (AUX)
What functions can I control with Apple Home?
You can adjust the thermostat's mode (heat,cool,auto)and target temperature. You can view the temperature,humidity, but you can't control the fan at this time(the fan will work automatically based on heating and cooling)
Why is my heat pump heating when it should be cooling, and cooling when it should be heating?
