Mike, like Lantley indicated. In the furnace application , only one of your 3 stats in your Paradigm will control your heat.
In our case, it is one of the two mounting near our control panel at the entry door. They target placement to be representative of the main living area average.
Hope your trip is going well and you are getting to see some fall foliage in TN.
Thank you @Lantley ! We have two thermostats in the hallway. Both will activate the furnace. I’m not sure why they wouldn’t have the bedroom wired to the furnace, but they don’t. It doesn’t make sense to me. Good news is it warmed up quickly!
Thanks Bryan. Fall colors are not in full swing unfortunately. The campground is very nice though (The Ridge Outdoors Resort). We’re headed to Alum Cave Trail and Chimney Tops for hiking tomorrow.
Thanks for the response on the thermostat! Does not make sense to me. I may look into rewiring a thermostat.
Glad you sorted it out
Interesting I have 2 thermostats in the hallway but only one controls the furnace.
Do you know why they wire it like that? The logic behind it? It’s not a big deal to have zoned heating from a cost perspective.
I've learned not to try a figure out RV builders logic.
However I can agree there is no need for both hallway thermostats to control the furnace since they are side by side.
One thermostat is sufficient. However this does not explain why the bedroom thermostat is AC only.
For the record I have not had any issues with only one thermostat operating the furnace.
I have added dedicated outlets and heat with space heaters whenever possible.
I use furnace as back up heat only.

Hi Mike, I am a bit confused as to how two thermostats would be tied to the furnace.
Are you sure that both actually activate the furnace? Or maybe they just installed two of the dual function stats by mistake.
Without some sort of damper system, I don’t understand how operation from two stats would work in different zones.
It would seem one would need to be King of the “call” and always fighting with the other unless maybe you turn it off completely when in that area. Also given the calibration inaccuracies between stats , it would seem challenging to get this to work out.
I know that they do make remote area sensors that can tie into the system, so the stat defers to the remote connection.
We usually have to offset are two main AC stats by two degrees so one ac doesn’t do all the work. They are both mounted in the same location.
Bryan that was sort of my thought too. But I know it's possible to have furnace work from different sensors.
I also know the RV world is not quite ready for prime time. Having a dual thermostat furnace maybe pushing their ability!
But I did consider turning hallway thermostat off while operating furnace from bedroom thermostat.
Technically this is all doable, just not in the RV world!

Funny, there was another forum thread discussion recently complaining that the furnace thermostat was in the bedroom and should be in the larger living area. Our new 2026 Avenue 25ML has the thermostat control in the bedroom, which I do not like. The temperature in the main living space is about 2-3 degrees cooler. I would prefer the bedroom be cooler, with the thermostat located in the larger living area. Just my preference.
Yup. The both spark it up. I agree the fact that they are one above the other made me think they misplaced the bedroom thermostat.
It’s not really zoned, I just called it that. It’s basically two thermostats making the call. It’s an easy wiring scheme, just run your R W Y wires from each controller to the terminals. In other words, run them in parallel. I guess you might need a jumper too thinking about some units. If one unit is still calling, the furnace will keep running.

It is interesting that both fire the furnace.
I guess, I still can’t comprehend if you make the modification, having one in the bedroom and one in the main living area. My hang up is when either one is calling, how would you prevent air from coming out of the duct if the other stat was satisfied?
My take is there is variable with t-stat calibration and even the mounting location in each rig that might be challenging to overcome.
If you pursue this project, please keep us posted on how you make out.
Enjoy your trip and travel safe!
You couldn’t. It’s kind of like how an Ecobee works with room sensors where if a room is occupied, and that room is not at the preferred temperature, the system turns on. The rest of the conditioned area would also be impacted, positively or negatively.
You can change that. On the furnace you will have a set of brown/blue wires connected by a Wago. You can run a thermostat wire from the brown terminal to the "W" location on your bedroom thermostat. Flip the dip switch on the thermostat to turn on the heat function and cycle the power on and off to the thermostat. This will now control the furnace from your bedroom and pick up the temp from in there to turn it on and off. You may want to disable the heat function via the dip switch on your other thermostat so you don't accidentally turn them both on.
