Aquahot question - B and C - 01-07-2024

Went to storage today to check on a couple of things.  Opened the Aquahot cabinet and noticed something running.  Of the 3 in a row on the attached picture the left one was on,  is this normal?
Thanks

Would be the lowest one.,... picture not rotated correctly.

The left pump normally supplies the rear heating loop, bedroom. It runs when the rear zone interior thermostat calls for heat. Turn rear thermostat to OFF.

If you remove the bottom clear relay, that should stop the rear zone and the related pump.

Thank you Mr Rudy.  Found the 1/2 bath thermostat was on.  
Thanks again.

Rudy, I have coach #385, it has 4 thermostats for heat, basement, bathroom, bedroom, living room.  The Aquahot was replaced 3 years ago at Newell and only has 3 pumps.  I do not have heat in the bedroom and living room and I think during the last major engine work the mechanics did not hook the bedroom back up.  Is it possible the two are run in series and this is why no heat.  All three pumps feel like they run, fans run when heat is called for from Thermostat.  I just have not torn apart the bed yet.  Thoughts?

Yep, just had an informative phone call with Rudy, this was one of his suggestions. I also understand how the zoning works now as well.  Like you Richard, he is a wealth of information!!
