Dometic Capacitive Touch Thermostat

[frustrated_user]

Temperature swing was too high in cold weather. Stat allows changing differential from 2 to 1 degree. Problem with "1d" is that the heat relay in Dometic controller chatters on and off very quickly. Stat and controller changed with no change. Dealer and Dometic no help. 2 degree differential, "2d", works ok but temp swing can get uncomfortable.

No idea if the Easy Touch RV thermostat would solve your problem. It can be set for a narrower "changing differential", but that may have the same result on the control box. An expensive "see if it works" solution...

As to the thermostat itself, if it controls both the AC & furnace, a household thermostat cannot replace it. As Doug points out, it sends a "control" signal to a box of electronics that then switches the AC or furnace off & on. As far as I know, the Easy Touch is the only alternative to the Dometic thermostat. I like the Easy touch much better - easier to set, shows the interior temperature, and provides both WiFi & Bluetooth control from your phone.

Yes, he can get the Easy Touch. Probably will fix his problem. Doug

Verify settings on thermostat to insure it is set up for your system. Heat pump or furnace?
Exact model of thermostat?
See page three System initialization Manual

Going to be next to impossible. The CT tstat only has 3 wires and MUST and CAN only communicate with the correct upper control board. The OP could get a new upper control board and old style tstat. BUT, there are only 3 wires run from the AC to the wall. Doug
