So my RV sat for a few weeks and since the kids left a light on, the house batteries were fully discharged. So I plugged it and on a 90 degree day the central heat kicked on - even though the thermostat was not even switched on. I tried changing the setting, even putting it on A/C - but still the central heat came off and on (mostly on) with seemingly no coorelation to the thermostat.
So after a full battery charge and normal coach conditions, the central heat still has a mind of it's own. So did a control board get weird, or did some relay latch with the low power condition? Can I correct this condtion? What I don't get is why the system ignores the thermostat....
Need to get this reliable so I can get in some fall camping with the kids.
Thanks for any assistance!
