Thermostat not showing furance
our Comfort control Thermostat doesn't show the furnace as an option. We do not know how to turn the furnace on. Help

On our motorhome we have 2 A/C units and 2 furnaces, all controlled by a single Comfort Control thermostat. There is a daisy-chained cable connection between all these devices. When we had our front A/C serviced once, the tech forgot to connect the RJ11 cable at the front A/C and this caused one of the furnaces to not register on the control switch... If this is a new problem, I would look for a loose connection at either an A/C or the furnace itself. It could also be a defective thermostat.
