Configuring Your 1F80 Programmable Thermostat 

Very helpful. It helped me to switch from F to Celsius. Thanks.

This helped a tremendous amount

Why does it not want to work on the HOTTEST or COLDEST DAYS OF THE YEAR?

@Xctome, that thermostat makes two clicks in all modes. For example, when calling for the heat pump, "emergency" gas/electric heat, and air conditioning this thermostat will make two clicks when kicking in.

What does it mean when it says system on +2 need to the temp

Do I put the heat on auto or on to work please
