You don't state temps and what you set the HP mode at. That said, RVP HP's IF YOU SET MORE THAN 5 DEGREES ABOVE THE INTERIOR TEMP, the HP's will NOT heat. So if the RV is 60 degrees and you set at 66 or above the HP's will not come on but your LP furnace will come on. Once the interior temp is within the 5 degree range the roof HP's will come ON. If you want the HP's yo heat up the unit, you must set the temp in 5 degree increments-----unit is 60 degrees, you set at 65, once 65 is met, you set at 70 and so on until your RV is at the temp you want.
