water pressure regulator?? [found to be basement thermostat]

There is a little brass (?) plate on the wall by the Water manifold that has a little twisty knob pointing to a series of numbers.
Is this to set the service pressure to the sinks/showers and so on?

thnx

Most people set it around 40 or 35 so the bay's don't freeze

could it be the thermostat for the basement, as it is referred to; that is the storage bays and water bays, mine was set at 40 degrees F (so f it freezes, the bays will be kept at 40 degrees by hot water heat thru registers generated by the aqua hot if it is on. My apologies if this has already been stated.

I have a water pressure regulator by the water manifold which controls the water pressure to the microphor toilet. If I remember correctly it is set between 25 and 35 psi to work in conjunction with the air pressure set at 65 for the microphor. Originally the water pressure regulator was under the microphor, I moved it to the manifold area for better access and reduce hidden connections that may leak at some time.  Tom

It is just for the bays where the water/waste tanks are located.  There are two heat exchanger/fan units, one on each end.  The bathroom has its own thermostat. 35 - 40 is about right.  But it is best to go out when it is colder and turn the knob until the fans come on.  Then you know what it is.  Knob, pointer and markings are not always precise.  If in doubt set it a bit higher.

You need to have the AH on, either electric or diesel for there to be heat to put into the bay.  If it is not the pump comes on, fluid flows, fans come on, and with no heat they run until your battery is dead.  At temps below 40, the electric side of the AH has limited capacity to keep up with the demand so plan on using the diesel or both.

In order for my bay heaters to work, I have a switch on the bottom side of my bathroom thermostat, that has to be on before they will work. Yours my be different.

The bay and the bath are on the same circuit on the aquahot.

If the thermostat is on and one or more of the power switches is on the bay thermostat can turn on its fan when needed separate from the baths.

Aqua hot is quoted here as having a 75 degree  rise in water temp. 

If the tank is colder the hot water output will be colder.

If you want to test the heat exchangers, submerge the sensing bulb in ice water. You can see one of the exchangers and probably hear the other which is likely hidden behind the utility bay wall.
