Remind me setting for basement AH heat to come on
Edit to fix my original errors:
If I recall correctly, zone 2 (for back of coach) must have AH set to on - on the thermostat, then basement rotary switch set to temp you want heat to begin at? So rotary set at 40 degrees, basement will begin to heat at 40 and below?
Updated Correction: zone 2 is bath, zone 3 bedroom.
