Heating and Cooling Zones
 
Coach is a 2012 Diplomat 43DFT with 3 ACís and Aquahot, 4 Zones on the thermostat.

The thermostat started acting up giving weird readings, like a set temp of 160. I think the zones got reprogrammed somehow and are all messed up.

I ďthinkĒ the cool settings and ACís are programmed properly. I am showing 3 AC zones on the thermostat and the zones correspond to the appropriate AC units. Zone 4 does not show an option for cooling.

As far as the Aquahot... Zone 1 controls the living room and kitchen area (3 registers). Zone 2 controls both the middle and rear bathrooms (1 register in each bathroom). Zone 3 controls the bedroom (1 register). Zone 4 does nothing as far as I can tell. I bumped the set temp up to 80 and none of the registers come on. I even checked the water center heater.

The owners manual indicates Zone 1 is the living room, Zone 2 is the kitchen, Zone 3 is the bedroom and Zone 4 is the bathroom/water center.

Iím wondering if the Aquahot zones are wired incorrectly? The sensor for zone 2 is in the kitchen area right on the main control panel, so it makes sense that the kitchen registers should be wired to zone 2.

I donít know what to make of zone 4. There is a sensor in the back bathroom for zone 4. If I heat it up the RV Comfort thermostat shows the increase in temperature for zone 4. I donít know how to activate the water center heater. I do see a box with an adjustment know and I tried turning it, but got no response.

Iím hoping someone with the same heating and cooling setup can tell me what heating zones control which registers.

Thanks,
Dan

in some coaches there is a manual thermostat on the ceiling of the wet bay, to the right of the heat register.
