Doutherm thermostat "comfort center"
Has anyone had problems with this thermostat?
like:
slow to respond after turning on
or the front a/c turning on for a split second while the furnace is running or after changing zones for the A/c having to wait quite a while b4 the a/c restarts. In other words this system is very slow to respond!!!
Need some help here. a replacement thermostat costs arount $100.00. So i dont want to just replace it and find the problem is somewher else. Or find that this is the way the system works. Comments?

The control boards on the air cond. units themselves have a built in time delay before operation begins. The t'stat does seem to also need a little time (10 seconds) after being turned on in cold weather to respond to changes made on its face. If after this warmup all else performs properly I don't think a new t'stat will be needed. If you are having trouble beyond this then you certainly could have a bad one.

I agree with Mike. The symptoms you are experiencing happen in mine also. I think they are normal. When making changes to the Duo-Therm be patient, your on vacation!

Our 5th wheel (see signature) has the same DuoTherm multi-zone thermostat for the 2 A/C units and the furnace. As the others have said, response is not instantaneous.

Just goes to prove that patience really is a virtue, I guess.

There is also big delays when using the heat pump mode. Sometimes the A/C-heat pump will defrost for several minutes before it puts out any heat. The manual is interesting reading on this subject.

The delays , I understand. however, while the furnace is up and running normally there are ocassions when the front A/C (not a heat pump)comes on, fan and compressor, for 10 seconds or less, then turns off. This can happen again in 10 minutes or so. I do not think this is normal. Do you?

No, this is not normal and although the T'stat could cause it; you could have a problem with the control board in the fron air cond. You would need to be prepared to trouble shoot the circuits in those 10 seconds to determine which is the culprit.
