Title: duo therm thermostat fan setting
Post by: 18360 on January 23, 2022, 11:22:31 am
     As you can see from my photo when I switch to the furnace setting. I don't have a fan option.  All off the other settings have the option of auto, low, med, high.  When I had the 115VAC switch on it the fan ran continuously (the same with the Aqua Hot).  This just happened this morning. 
    We were on a little trip and stayed over one night with no hookups, but I didn't even have the heat on at all.  I ran the generator a little bit with the AC on.  But that's all I did.  We are back with full hookup, and I noticed about this fan thing.
    Any ideas

Thanks

Rick:

Our furnace does not have a fan/speed option.

Four-button Dometic thermostat does not have a fan setting because the propane furnace has a single speed fan. The heat pump is the air conditioners run in reverse freon flow and it has multi-speed fan settings, just like for the cool setting.

Your right.  It got a little chilly last night, so the fan was on most of the night.  I should have turned the Aqua Hot on.
