Having an issue with both five button thermostats blanking out occasionally. I have no idea what is causing this as the HVAC is not even being used when it happens. I spoke to the guys at Beaver Coach Works in Bend and was told they have seen this before. Said to pull the fuse to the thermostats located in the Intelletec panel and put it back in. That will reset the system. Sure enough it fixed the problem. I have had to pull that fuse to reset the system a half dozen times over the past month. The fuse is never blown just needs a restart.

Would like to know if any of you have experienced this and know what the root cause could be. Gremlins lurking for sure.

Thanks

That's a common problem with the CCC 5-button thermostats. Below is the reset procedure for them.

16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection.

Thanks Joe for the quick reply.

My question is: if I go through the reset procedure you have outlined is that all there is for a permanent fix? This won't mess up any programming will it? I haven't messed with any dip switches.

I just did the reset (tracking a different problem) and it didn't mess with any of the functions. The temperatures are now a wee bit closer.

I don't know of a permanent fix.

I had my thermostat going totally blank for no reason.

Open the AC vents on the ceiling and check all the telephone connectors
These connections can be troublesome.
Unplug and replug a few times to clean them out good.

Could be they are "wiggling" and make your thermostat lose it memory.

Doing the reset does not screw up anything. It is also not a permanent fix. I don't think there IS a permanent fix for that!

One thing that I have found is that I had to turn off ALL florescent lights before doing the reset, otherwise it would not reset properly and show an error! I have now replaced all the florescent with LED's, but wanted to caution you about that.
