Why does my furnace come on when electric heat is selected on the thermostat? (Coleman Mach 9630A3361 Digital RV Heat Pump Wall Thermostat

If there is a difference of roughly 5 or more degrees and you choose electric heat, the furnace will kick on and run until you are up to set temperature, then just the electric heat will be used within the 5 degrees, instead of the furnace.
