Thermostat

[NFranzen]

I have the attached thermostat below that came on a new to us camper we just bought. We have heat and AC and it controls both. I am wanting to change it out with a digital thermostat. What should I be looking for? Thanks for the help.

There are various guides online of how to adapt Hunter and Honeywell brand residential thermostats for RV use. Here is a link to one of many youtube videos that show the process step by step, Some people add a high/low fan switch, some just wire them to be high fan all the time.

John did this 5 years ago, here is his write-up of the procedure. Replacing the Coleman Mach thermostat with an Ecobee

Coleman-Mach offers a variety of digital thermostats for RVs, one or more of which ought to easily replace your older analog model. Looks like you need a model that handles both heating (furnace) and cooling. Does your rig have a heat pump or plain a/c? The thermostats controls are a bit different.

What is your make/model? it makes a difference which 'stat is required. Some Coleman digital 'stats for RV's are 24V and might require a transformer to operate in an aftermarket application..

Most that are rated for 24v don't actually require it and run fine on 12v. Ditto for residential thermostats.

Thanks for that information Gary. That gives me the green-light to proceed with my idea to install an Ecobee 4 WiFi thermostat in our MH. The 24V was my stumbling block and a transformer appeared to be the only solution.
That would give me the ability to monitor inside temperature, change settings, etc. from anywhere I had cellular phone service via the Ecobee website.

This has AC and a furnace as well. I would think I could replace it with one that handles that and uses AA or AAA batteries to power it, correct?

Yes with the style of thermostat shown in the first post

The easiest thing to do is replace it with one that is designed to directly replace what you have.
