Heather - By electric furnace I assume you are using the heat pump, which is usually installed on one of the A/C units, but depending on options could be on both A/C's. If only 1 HVAC multi-function controller has the electric heat option you have only 1 heat pump.

When using the heat pump the system is set up that the propane furnace will automatically kick in if the heat pump cannot supply sufficient heat to maintain the requested temperature, or the difference between requested temperature and ambient temperature is above a set level. During the PDI I seem to recall our coach is about 10 degrees. Therefore, if we select a temperature more than 10 degrees above the ambient temperature the heat pump starts, but the furnace kicks in fairly quickly.

To save the furnace from kicking in lower the temperature setting and increase it as the coach heats up. If you have the fireplace this kicks out considerable heat and also saves using propane when it is rather chilly.
