RV DIGITAL THERMOSTAT CHEAP AND EASY INSTALL! 

*Solid, **Fastly.Cool** and gets the job done. For rooms where window-mounted air conditioning is not an option, this works very well. Easy set up, rapid cooling, and great design.*

Just wanted to take a moment and say a big Thank You to you Jared for the great video. My wife and i watched it several times and today we took the plunge and the system is working great. So thank you again it really helped us. The RV dealer wanted almost 300 for the thermostat and labour to install.

bought a programmable thermostat and could not get it to work using conventional wiring. thanks to your video I got it wired correctly and it works great. I thought I had a bad thermostat which would not have been the first one. big thank you for your video.

Awe..... look at how young Jared is in this vid. Little puppy....👍🏻

My been giving me crap for a long time a friend gave me a camper thermostat and couldnt get it to work to save my life today i found your video ran out collected all the stuff and did everything you showed in the video works great thanks for sharing. Took longer to go out and round all the stuff needed then it did to do the swap

Hey Jared, just to let you know this was very helpful, Thanks, Harry Irvine

Thanks for the ideas you have shared here.

Really clear instructions. Thanks!

Very Well done My last Travel trailer was a 2003 Rockwood just traded for a 2017 Coachmen. the problem I had with the last trailer was over a period of 5yrs it had three thermostats that I replaced due to Short cycling and inconsistent temp (way off) from research I have found that for the most part the Duo Therm Thermostat is JUNK and the new digital one from Dometic is no Prize that's the one in my new Rv but its good to know that you can use something off the shelf like you did . rather than go to an Rv store and buy same Junk again . yours will last the life of the RV

Toggle switch GSW-12 SPDT switch (Ace Hardware, Amazon, Home Depot, etc.), it is a two position switch On-On, in this case it would be a fan Hi-Lo. Follow Jareds instructions in wiring up the toggle switch. Google "Dometic bulletin A27-8C" and see page six, for early model wiring identification & troubleshooting.

24-volt thermostat running off a 12 volt battery? I have about 20 wires coming out of my wall. You're lucky

Sorry Chris, just realized I don't need "B" brown low fan. You did not need a thermostat with that connect because you installed a remote switch. The Honeywell RTH221B uses high speed fan blue only. Perfect choice, I'm not concerned about dual speeds.Thanks,Dan

When hooking up the toggle switch for high and low where do you hook up that red wire in relation to the terminal for the new thermostat?

This is easily the most helpful video I’ve found so far! One question: if one were to accept a single speed on the fan, could the toggle be omitted?

My model would not work with just the high fan wire I needed to connect both the fan wires together make it run on high

Funny, you showed a red wire coming from the switch to the thermostat and then you show wiring up a brown wire to the fan terminal?

Thank you 🙏🏼

If you loose the bAtteries during a heating or cooling process, the thermostat will stop every thing or it will continu in the same setting ?

You hooked the black to rc but that’s ground isn’t it? And you didn’t say what to do with the red one with was originally hooked to +7.5v terminal on old stat. Can you help?

Thanks!

Before I remove the heater.. Is it true that I can disconnect the blue wires..touch them together and if the heater lights..my thermostat is out?...

Did u leave or use a jumper to run both a/c and furnace , I’ve watched your video serval times , I cannot get my thermostat to work

The wire that goes on G, where did you connect it on the on and off switch? We have everything down but that. Thank you

Jared, my RV thermostat runs off 12 volt, I have the RV parked on a lot I own and have never and will never travel with it, is there a way to convert the 12 volt thermostat to 110 volt? I have 30 amp service and the only thing I really need 12 volt for is the AC thermostat...

Where did you attach the red 7.5 wire? Everything else looks great.

Will the model you are installing be applicable for most Dometic models? Thank you.

I'm confused.. Home Depot has the Honeywell but it's 24 vdc. How did you get this one to work on 7.5 vdc. Tha's what mine says it is.

Thanks Chris. The Honeywell installation manual section 2 for wiring does not show a connect for my Duo-therm fan brown wire. Where does it go?Dan

I have the same wiring and cant make it work so are you saying not to use the red wire on the +7.5 and put the black wire to the rc on t stat sir

That's a 12volt thermostat. The breaker did nothing to safe the power to the thermostat.

We have duct A/C and we installed the same thermostat, so will the fan from the A/C always be running even when we are running the heater?

Will any thermostat work?

i see the red wire when u put the new ther up but you didnt hook it up , i have the same unit but my ground is green and i see yours is black. so where did the red wire that is the 7.5 v feed go . i cant see where you hooked it up to

Great video! Are those t-sat pricey?

Hello Jared. Im trying to change my thermostat. Is there anyway I can contact you or help ?

Great video. We have a Duo Therm t-stat similar to the one shown (just different colors in the block, but 6 wires just the same). I have a question - we don't use the A/C, so how would I wire the RTH221B1039 to operate just the furnace? Many thanks.

Eliminate the thermostat all together ...I've now watched 3 break...last night it was mine...!!! When the unit isn't being lived in the thermostat is irrelevant...you need heat or you need cold...on or off Can you set it up with 2 switches Furnace/AC...??? Mine came off the wall somewhat abruptly...

what was the model number of the Honeywell thermostat shown in your 6/13/2016 video?

Doesn't anyone have a video showing the old analog to the dometic digital? The instructions do now show how to hook up the analog 6 wire system to the digital 3 wire system. The instructions show you how to turn a thermostat on and off, ugh.

Hey, just a quick statement, you never gave the cruising reference between what you took a picture of vs what you put in. That video was not helpful at all..

Turning off the main 120 Volt breaker does not turn off the 12 Volt circuit for the furnace. Granted, 12 Volt will not shock you much, but crossing those wires could damage the furnace. So, having omitted that I turned off your video and did not subscribe. You are not expert nor should you be giving advice. Tell us about your camping locations.

What????? You completely disconnected the power so how could a touching wire during disassembly of the old unit cause any issues? Answer it can’t!
