Scenario:
On our most recent trip the weather was moderate so we just used the electric part of the AH. When the weather turned colder I decided to turn on the diesel burner. The light came on but the AH blower did not start. As this was our last day I did not troubleshoot the no start condition.
When we got back to the barn I tried the AH and it worked just fine.
Question:
If the water temp. is at set point (from the electric element) would that keep the AH from starting on diesel?
If I understand the question correctly, my diesel does not fire the AH if the electric is keeping the AH at the right temp. So at 50 degrees ambient, as an example, the AH if left on both diesel and elec will seldom if ever use the diesel
Hope helps

I did turn off the electric element before I switched on the diesel. I am sure the water temp was still at set point.
Old hippie, you are correct. As lon as the electric element keeps the liquid at the proper temp, the diesel should not come on.
+1 what Mike and rbark said. :D
cut on temp for electric is 185. Diesel is 175.
So, can the diesel be on at the same time as the electric? or should you use one or the other?
You can have them both on
Yes
Both is perfect
Thanks all.
Still learn'n....
If the electric element cannot maintain the boiler temp over the 175 degrees then the diesel burner comes on.
Seperate systems. Different cut on sensors. Different cut off temp sensors as far as I know
All of the above is correct ----- till you have a young enough coach to have a heater controlled by an electronic control board.
Then the one control thermostat turns on which ever heat source is on and then off all at the same time.
