Domestic wall dial/Furnace/airconditioner

[Strwbry]

I live in a RV resort. Yesterday they moved me to a new spot. I when to turn on my furnace as normal in the middle of the night and it was blowing cold air and warm. The propane guy came and changed our tank and filled. The hose from the small tanks had a bad fitting to the propane. He said he by passed it. I have tried several times to get the furnace to run as normal. Both the air condition and heater come on at the same time and that has never happened before.

At the thermostat, press whatever button you need to to put it FAN mode. Then using the up/down buttons change it to AUTO, and the AC fan won’t blow when you operate the furnace.

You may need to purge the air from the propane system, light the burners and run the water heater on LP for a minute.
