I have a Trane air to air heat pump. Most of the time it's OK, but the
theromstat is set too low. The furnace dosen't come on until about 21
degrees. I'd like to set it to 30 or 35 degrees. Can anyone tell me
where the adjustment for a thermostat is typically located?
I hate to call a repair guy to make a simple adjustment if I could do
it myself.

TIA,
J.A. Michel

Most of the OutDoor thermostat are put out inside the electric
compartment of the condenser unit outside.
