Aqua hot pump 2 running

I noticed things getting pretty warm under the bed lately. (No it's not bc of my added storage)

Turns out pump 2 is running when the burner is on. Pump 1 is off as it should be.

Anybody know what triggers the pumps? Both thermostats have the furnace button off. Also turned the thermostat in my wet bay off. Even with all thermostats off pump 2 is running.

It's not that the bedroom AC isn't keeping up, just seems silly to be pumping heat into the bedroom when its 98 out.

Assume the burner is on just to get hot water? I always thought the pumps were controlled by zone which is controlled by the thermostat. Unless it automatically turns a pump on just to circulate coolant once it reaches a certain temp? You can always unplug the pump at the connector. Any fault lights on the controller?

Is the aqua hot your hot water source or do you have a separate hot water tank or Truma.

No fault lights all is green.

Yes just using the burner for hot water. Would rather not pump heat into the coach otherwise

Technically if the fan is not on, it’s not necessarily pushing heat. Just the hoses are warm. I’d have to ask the Aquahot guys if that is normal.

Sure but theres still *some* heat that gets pushed. This is very evident when opening the bed. I'll stick a thermo down there and see how warm it actually is. Just seems odd.

Looks like its running about 100 deg F under the bed with the AC at 70 in the bedroom. While its not overpowering the AC or anything it still seems kind of counter productive.
