I have a 2022 Grand Design 376ths with 3 a/c units, one of which is a Coleman Mach heat pump.  I know that the are designed to swith to gas heating wen the outside temperature falls below 40 or 35 degrees, but mine is going into gas override and it's only 56 degrees outside.  How can I fix that?  It's usin up my gas.

 Coleman heat pump will automatically switch to propane if the temperature difference between the thermostat setting and ambient inside air is four or more degrees. I have to turn the thermostat on and quickly run the thermostat so that it is 3 or fewer degrees from ambient.
