Programmable thermostats

I recently took delivery of 2018 Rockwood 2706ws with a suburban furnace. I am seeing if anyone has installed a programmable digital thermostat and if so have you had any issues or does it work just fine? Thank you in advance!

Which brand and model of thermostat and A/C do you have?

If you have a Dometic A/C and digital thermostat you'll have a hard time adding a programmable t-stat unless your unit has separate thermostats for the furnace and A/C? If so then it's easy to install a programmable t-stat for the furnace.

If you have a Coleman A/C then you can use a programmable t-stat for both furnace and A/C.

It's one of the more common upgrades that people do on RVs. If you search here and elsewhere on the web, you'll find lots of instruction and options for upgrades. Just like with homes, there are differences in RV HVAC systems that make the mod a bit more complicated than simple plug and play. Some have integrated AC controls, some do not, some have multiple fan speeds, etc. This affects the type of thermostats that are most appropriate, what wires get connected to where, which wires can be ignored, and whether you need an external switch for fan control.

Here is one such thread, though it is a few years old.

Good luck.

Swapping out an analog for a digital is my Mod #1. The following may be helpful, or at least make your smarter:

I had a Coleman-Mach analog

and replaced it with a Honeywell RTH111.

The RTH111 is not programmable, but the RTH211 is the programmable version. You can see they look similar:

Wiring is the same, so the following applies to either unit:

The Coleman-Mach uses trailer power for it's "brains," so it requires a ground wire. The Honeywell uses battery power for it's brains, so you don't re-connect the ground wire, just tape it off.

The Coleman-Mach has a switch to chose fan speed for the AC. The Honeywell doesn't do two speeds, so you either pick the one you want and hook up just that wire, OR you add a separate switch to allow you to chose fan speed.

I've attached a wiring diagram showing the old Coleman-Mach and the new Honeywell. Note that all the stuff inside the big dotted line box on the far right is a "representation" of what's going on inside the thermostat.

If you don't need programming, you can simply replace the analog Coleman-Mach with a digital one; it's plug-and-play:

If you have a Dometic, things get a bit more complicated, as apparently the furnace power runs through the AC unit somehow.
