Hi there. I have an RVComfort.ZC thermostat and I noticed that it is not 'reporting' the correct inside temperature. It is 90 degrees in the coach (just started the AC) and the Tstat is reporting 66 degrees for that zone. Is this a simple fix by resetting or do you think the remote sensor is bad or even the actual thermostat is bad? Note: AC works just fine and no issues at all.

Thanks in advance,

Ian

I checked the website
Rvcomfort.com

It seems to have a manual for your thermostat and when the temperature will display and when it will not.

It seems in the manual if your A/C is running the set temperature displays not the actual room temp. I may be mis reading the manual however.

I have had 4 different RV’s to date and not one would display the zone temperature. They would display the temperature I wanted them to be.

If I want Zone 1 to be 70 I set it at 70. That is the number mine would then display. Zone 2 could be set to 68 and would display 68 when looked at.

Hope this helps but ??

Thanks for the reply however in my current situation, in an RV at 90 degrees, if I want to set the thermostat to 70, the AC would never turn on because the thermostat already thinks that its 66 degrees in the coach...that's my problem.

If that thermostat has remote sensors, find the wiring for the sensor and re-crimp the connections. I've had to do that a couple of times with my thermostats.

I revised my original response while you where replying. Check the website I referenced in my revised answer.

Crimp at the tstat side?

Thanks for the info. On my tstat, without touching it, the temp showing is the room temp. If you trigger the up/down buttons, that triggers the select temp reading. After you make you adjustment, the room temp comes back. Make sense?

Yes it does, thanks.

Try LT Dans fix.

I would suspect the connections on the remote end would be the ones needing re crimping.

Yes, if the sensors are screwed to the ceiling or wall, pull the wiring out and recrimp the connectors. The connections get a little corroded and the increased resistance causes faulty readings. Removing the connectors and soldering the wires is the best solution.

Got cha' yes, they are screwed in the wall. I will make sure that I pack my soldering gun and crimpers with me the next time I go over. Thanks !

Have you removed cover and reset thermostat?

Thanks for the reply. Not yet. How do you reset the thermostat? Unplug the fuse for 5 minutes?

Yes remove fuse

Has anyone had the room temperature reading show ‘00’ but changes to the set point are showing as well as the zone and mode changes and the A/C unit will not come on? Tried all the easy stuff: reprogramming, cutting all the power, DC & AC, and checked the wiring. It apparently is not getting a temperature reading but is that a thermostat problem or the control unit upstairs? Thermostat is a RVComfort.zc #8330D335 operating a Coleman Mach 8 Plus A/C w/ Heat Pump.
Any ideas will be appreciated.
