3 zone thermostat

[num1dgh]

Has anyone had a problem with the 3rd zone of their hydrohot not coming on due to their thermostat, or are there other reasons that the 3rd zone won't come on? After fiddling with the thermostat, zone 3 will eventually kick on, but it's not consistent. Zones 1 and 2 work just fine with no problem.

Please give us more information about the wall thermostat and the actual scenario of what is not working concerning the Hydrohot. Which appears to be working but the other is not will help in diagnosing where to start and where not to waste time with.

The ComfortAir thermostat works as it should on electric heat, but that is not very effective when it's below about 50 degrees outside. The two front zones (1 and 2) will work as they should on diesel, but the rear heat (zone 3) will not kick on with any regularity. If we tap on the thermostat and move the on/off switch back and forth, we can sometimes get it to go on . . . not very helpful when you want to set it to a minimum heat so that it goes on by itself (theoretically) when the temperature reaches a certain temperature in the middle of the night. We've checked, and hot water is reaching the 2 radiators in that zone, so we are thinking it might be the thermostat that is not causing the fans to kick on. Has anyone else experienced this?

My setup is like Dennis Parker. Electric heat zones 1,2,& 3. Hydrohot zones 1 & 3. Mine have heat outlets in front, mid, and back of coach but only two thermostat zones.

I wondered about that. It is zone 3 in the bedroom (under washer/dryer cabinet and under shower) that works sporadically. A bit FREEZING if one gets up in the middle of the night!! Have you ever replaced your thermostat or had a problem with zone 3?

I've not had problems with the system (knock on wood), I usually have to get up early AM (nature calls) and I flip on the floor heat.....gets nice and toasty for whenever we get out of bed.

I have not had a problem like yours !! I'm not sure where you live in Calif but
if there is a Auqua hot person in your area you should contact him and let him
help you and at the same time he can service it for you
Merry Xmas
