I have a couple of questions about bay heat. In the water manifold compartment on right side, I have a small thermostat. It is to the right of the water system control valves. The thing is, the settings are from 0 to 50 degrees. This confuses me. What is this temperature referencing, and what is it controlling? Also, as I understand it, the thermostat in the bathroom also controls the heat in the the storage bays. Is this correct?
Thanks, Mike
What you pictured is the Thermostat for the bays. It would call for heat if lower than what you set it for. You must also leave heat left on inside to make it work. I think the Bathroom heat also blows into the bays, but then only if the bathroom calls for heat.
YEs it is the bay heater thermostat. You need to have the bathroom on or that zone pump on the aquahot will not work.
Yetch, Eric & John,
The bathroom thermostat controls heat in the bathroom only. The basement thermostat controls heat in the basement only.
Now the coolant loop supplied by pump 2 goes to the bathroom fan coil and to the basement fan coil. So if either the bathroom or basement thermostat calls for heat, pump 2 supplies hot coolant to both fan coils. ONLY the fan of the thermostat calling for heat turns on - not both fans.
With the bathroom thermostat set to as low a temp as is possible or even disconnected, the basement thermostat can turn on pump 2 and the basement fan.
Hope this helps you all.
Recommended setting for the thermostat is 40 degrees.

Thank you Rudy for the direct, clear explanation. I've read so much conflicting info that I was not sure how any of that worked. I'm going to bookmark this.
Mark,
As usual, Rudy and Roger provided excellent expert advice regarding bay heat for the coaches with Aqua-Hot. Some of us in the "Poortravel Club" :P don't have Aqua-Hot systems. Your signature block indicates that you have a U295. Most of the U295 coaches have two propane furnaces rather than Aqua-Hot. On our U295, the rear furnace supplies heat to the "service entrance" bay and "water pump" bay via 2" ducts from the rear furnace.
I replaced the "open" registers for the rear furnace with adjustable registers. When we are in cold temperatures for several days, I normally close the registers partially to get more heat into the bays. IIRC, the specifications for the furnace call for at least two fully open 4" registers to assure sufficient air flow for proper operation of the furnace. I normally operate three partially open 4" registers to the "house" and two fully open 2" ducts to the basement. The adjustments have served us well for distributing some heat to bays containing water.
Thanks for the info.

Not mine. But technically it is Hydro-hot. Rudy has already advised me extensively and expertly on a repair/adjustment.
