Hello,

Trying to get some clarification on the heating process on my RV. It is the 2014 Keystone Raptor 410LEV with the atwood mobile model 8535-iv dcll furnace heat.

When I have the heat set on electric..the furnace is kicking on. The overhead a/c with the heat elements kick on from time to time as well. Now when the furnace heat does turn on…it is usually due to the RV being much lower temperature inside than what the thermostat is set at. So is that normal, in electric mode, the furnace heat to kick to catch it back up.

Thanks for any clarification anyone can provide. Not having much luck searching.

I have heat pump style a/c units. I can get heat from them depending on what the outside temps are. If it is too cold outside for the heat pumps, the control kicks on the gas furnace to reach the temp you set it at. This might be the answer for you as well. I know I was puzzled when it happened to me and searching a few threads on this forum I figured it out. Hope this helps.

If you have a heat pump as opposed to electric heat strips, if the outside temp is below 38 or 40º, the heat pump won't work. The furnace will come on instead even though heat pump is selected on the thermostat.

Also, some setups are programmed to have the furnace come on if the actual temp is more than a certain amount below the set point even though the thermostat is set for electric heat. The reason for that is the furnace will heat the RV more quickly than the heat pump or electric heat strips. Once the temperature in the RV gets closer to the set point, electric will take over if that's what is set on the thermostat.

On our system, if the temperature in the RV is more than 3 degrees cooler than the setpoint, it will bring on the gas furnace for a couple of cycles and then go to the heat pump.

If you are asking if the set temperature and the actual temp in the RV are considerably different, they were in my MH. My thermostat is located on the outside wall of the bathroom. When the door was closed and the heat was running, the bath room got really warm, heating the back of the thermostat and turned the furnace off. The rest of the MH got colder but the bathroom wall remained warm, not letting the furnace restart. Solution? Keep the bathroom door open!
