Customer Question
I have a Bryant...

I have a Bryant 2 stage with an evolution thermostat. Very cold right now here in Chicago. I kep getting a system malfunction message to call techinician. The furnace shuts down but the fan is still on. I have turned it off and back on and that got it running for a little while and then the same problem.

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

The furnace itself runs but shuts itself down and then can get running again so not sure.

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

I would like to see if there is an overide option in the event the thermostat is shutting it down. It is -2 degrees outside.
