At ambient temps below 45, the heat pump is very inefficient and will not keep the RV warm at all. That's why the furnace kicks on if outside temps are below 45--it's backup for the heat pump.

If you want to avoid burning propane, get some small electric space heaters to help the heat pump along.

The heat pump is not going to blow very warm air, although it will be warmer than outside air. That's the nature of a heat pump. Quite honestly you might be more comfortable with space heaters alone and leave the heat pump OFF.

I should also mention we will be boondocking in national parks. Does the heat pump only work on AC power? Also, how do we ensure the furnace kicks on automatically? Also, we don't mind dressing warmly :)

Hello. We have an atwood AC-1511 system. The thermostat does not go below 60 degrees. We will be encountering 25-40 degree F weather and we don't want to burn through our propane but also don't want our coach to go below ~45 degrees. Is there a way to set it below 60? Also, in the manual it says: "the unit will heat in the heat pump mode in ambient temperatures above approx 45 degrees f. The furnace with automatically engage at ambient temperatures below approx 45 degrees." What is a heat pump, and what do we need to do to ensure the automatic 45 degrees furnace turn on? Thanks guys i really appreciate your help!

Also, we are new full-timers, been in our RV about 3 months now! :)
