Customer Question
I just installed a...

I just installed a RTH636OD thermostat on a heat pump system with backup heat source. Heat work fine. When calling for cool air, hot air is venting. How can I determine if my system is one stage or two stage? Does this sound like a settings issue or a wiring issue?

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

There were two questions in the setting set up I did not know the answer to, number of states was one of them.

Contractor's Assistant: Do you plan on doing the work yourself?

I am trying to.

When you set the t-stat to cool and you say heat comes out, Is the outdoor unit running?

It is in the system setup in your manual.
