Troubleshooting
Heating or cooling doesn’t turn on when the
setpoint is above or below the room temperature
To prevent damaging the compressor, the thermostat
inserts a delay when cycling the compressor. If you
think the system should be on and it’s not, change the
setpoint to 2 degrees beyond the current setpoint
and wait 5 minutes to see if the system turns on.
If not, contact a local HVAC professional.
Heat pump is “cooling when it should be heating”
or “heating when it should be cooling”
Some heat pumps use the O terminal, while others
use the B terminal. Try switching the O or B wire
to the opposite terminal. Contact a local HVAC
professional for further assistance.

On the wiring detection screen, select NO.
