Oasis Hydronic Heater

[Jerryw]

I have a question about my Oasis Hydronic Heater on my 2014 Ventana motorhome. I leave the main power switch located in the basement in the "on" position all season. I turn the inside switches "off" when not in use in my driveway. My motorhome is always plugged into shore power at home although it is only a 30 amp "plug in" but I think is enough for the inverter charger, lights and even for one air conditioner. I turn off the main switch to the Oasis after winterizing until the next season. Should that "main" switch be turned off or on when not in use either during season of use or after winterizing when it will be sitting for for 3+ months not is use but plugged into shore power?
Thanks for any input?

I have never turned the power off on the unit itself, AC 1N2 off, burner off, nothing runs. Unit just has power to the control board. Never had any problems.
