Thermostat Registers Colderer Temperature

[NOJO RV]

The front thermostat on my DynaQuest 3801TS registers a colder temperature than the actual room temperature at night. I think there is a cold draft in the wall behind the thermostat. Has anyone else experienced this problem? I was thinking about pulling the unit off the wall and seeing if I can put some insulation around it and the remote temp probe.

If it’s on an outside wall very possible, I have one of those weather stations in the trl. The in house unit was close to window a few inches probably. I have had intentions to install the outside side but haven’t because not sure how or where I want to. Anyway the outside unit was sitting maybe 8-10 inches away on same counter just closer to the interior edge and was 4-5 degrees warmer all week.

I removed ours and stuffed a bunch of foam insulation in the wall behind it. It helped marginally, but the thermostat setting rarely matches our thermometer in the coach. We ended up filing it in the extra wide "camper quarks" folder so far.

If you have the “old school”, pre Firefly thermostats on the wall you can swap them out for these Micro-air thermostats that allow you to make a temperature sensor offset to accommodate the difference. One of the best upgrades we have done on our 3801 TS. Also allows WiFi and Bluetooth control of your thermostats. If you have the Firefly system these are not applicable.

Last I checked these are not yet available for the GE systems.

[MoJoe1003]

The GE compatible thermostats are not available yet, however they do have them in development and should be available soon. You can sign up for email notification when they become available. They are available for the Coleman-Mach units, which is what we have.

Always a bad idea to mount a thermostat on an outside wall.

Any crude, single-value offset you program into a "digital" thermostat will be accurate for winter heat and twice as far off for summer air-conditioning, or vice-versa. Hope the one you are thinking about can compensate in both directions.

It can be adjusted in both directions and I do make that adjustment based on the seasonality. Although, I don’t feel very crude when I do it…LOL!

And you are going to all that trouble when all you have to do is raise the temp on thermostat up or down to what feels comfortable. And remember the setting.

get one of them red dot digital thermometers...



if you want to stuff some insulation into the wall ... point and shoot then no guessing
look for other sources of drafts and heat loss.
Slides are notorious for it

If I’m not mistaken the temperature is sensed by a remote mounted thermistor. At least mine is. My living room sensor is mounted in the tower on the side next to the living room slide. It gets affected from the heat and cold in the tower as well as the draft from the slide seals. I have been meaning to move it to an inside wall but haven’t gotten around to it. The bedroom thermistor is mounted on an inside wall and it works perfectly.
