Customer Question
I recently bought a...

I recently bought a Honeywell thermostat. Model RHTL 3550. It works for A/C but not for heat. I do not know if it was not installed properly, or if there is something wrong with the unit itself.

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

The settings are OK. Not sure what you mean about the filters. The old thermostat, also Honeywell, worked fine but it was programmable and I wanted a non-prog.

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

No. I was hoping Honeywell either has local technicians or has a way for me to find someone. I do not want to use the handyman who did the original work because he has admitted he does not know how to deal with the problem.

Contractor's Assistant: Anything else we should know to help you best?

The furnace goes on when Heat is selected but apparently the thermostat is not activating the electric pilot light.
