2016 Montana 3791RD thermostat help

My husband and I recently had to replace one of our air conditioner units last this summer. We got the new one installed and all was good, or so we thought... Apparantly the mobile RV repair service was a fly by night and I canít get any response from her now that I need her help. So when they changed the unit, my thermostat stopped recognizing the heater. (Only one thermostat). Anyone have any ideas?

You should only have one of the thermostats control the heater. Or maybe I am misreading your post?

Had this happen on our old rig and it was a phone cord like cable that they had left unplugged at the AC unit it'self. We had the old style AC and just had to take the cover off inside and plug it in.

I have 2 thermostats,2016 Montana 3791RD,as well.Was wondering if both thermostat controls work the AC and the Heater?
The Bedroom thermostat will turn on the AC,but not the heat.
I am having problems with the thermostat in living room not registering the heat when I turn degrees up or down.I turn off the control completely and it runs ok for a bit then back to same problem.
I have a silver box, with a telephone,CAT 5 plug adapter connections on it,but cant find where this box is to replace...I need help..
