Digital Thermostat

havnfun · 04-12-2014, 05:10 PM

Now that the Hunter digital thermostats are impossible to find, what's the next alternative. Want an un-programable one similar to Hunter 42999?
Anybody know of one like the Hunter and where to buy it?

I purchased a Honeywell RTH111B for my Jayco 32BHDS. After a lot of research, this model kept coming up as a recommendation. Was going to hook it up this afternoon but forgot a pair of wire cutters. If anyone has wired this before in a Jayco I'd love to here their advice and it would probably save me some trial and error.

If I attached it correctly, here are pics of the wiring for the factory thermosate on a Jayco 32BHDS (Analog Coleman Coleman Mach thermostat running Atwood heater) as well as the connections for the Honeywell RTH111B.

Thanks. I've seen that RTH111B at HD before but wasn't sure it would work with my Coleman-Mach. Looks like just what I need. When we get back home next week from AZ, I will get one and install it. How did you install a low/high fan control toggle, if possible?

Have not installed it yet - didn't have the right tools for the job. Will be back at the CG mid-May. Would love to figure out the wiring in advance, otherwise I'll take my best guesses until everything works.

As far as the high/low fan, there are others than had recommended putting in a toggle switch, but my plan is to only connect the low (or the high - depending on which I find first) and terminate the other one. We don't really use the fan alone, and find the AC works well enough on high or low.

I found an older post that made reference that the blue wire is not connected and just terminated? Does this sound correct to anyone?

Here's a couple good JOF reference threads on digital thermostat installations:

Thanks for the replies - I'll be trying this out next camping trip in May.

Looks like there is a second thread going on the same topic. Someone posted another great resource in that thread that I'll post here in case someone searches for this in the future.
