But.........it has never turned the AC fan on either. Not sure why, but even with the original mechanical t-stat, I didn’t have manual control of the AC fan. Just high and low speed, which I’ve found isn’t really needed.
Keep in mind that what I’m wanting (needing) to ensure is that my black and gray tanks and valves don’t freeze when I’m not using the LP furnace as my primary source of heat. Only the furnace is ducted to the tank area. I can keep the air stirred inside the camper by other, quieter means than by running the AC fan.
