Hi everyone! We ended up buying the 2008 I asked everyone about. It turned out to be the 34 RLB3. We are out in it for the 3rd time - 1st time using the heater. We have a digital thermostat (RV Comfort) that appears to control the A/C and heat. (Heat Pump I assume.)
We just turned it to heat and it seemed to come on fine. Smelled "heat" - warm air blowing. It is ducted for the entire 35' trailer. One Unit. When we first turned it on it was blowing out the ceiling and floor vents. We were told by others the heat should only blow out of the floor vents and the A/C out of the ceiling. Is this correct?
We could hear the unit kick on. A few minutes ago it seemed to kick off - but then we smelled 'heat' (just like when we first turned it on) and it is only blowing out the ceiling vents now. Thermostat has not reached the temperature we have it set at. Now it has kicked back on and the air is blowing out the floor again. Fan is set to auto. Is this functioning normally? It is getting nice and toasty - but I am wondering why it's blowing out of the ceiling if it's not supposed too. (Ceiling air is warmish, Floor is much warmer.)
Second part of this question - above the digital thermostat are two non-digital thermostats. The kind homes had before digital were available. What are these for? They don't seem to do anything...
Without knowing exactly what you have, here is my best guess. You probably have an electric heat strip in the air conditioner, not a heat pump. The heat from the floor is likely the propane furnace providing heat.
It is normal for the furnace to assist the heat strip till the temperature is near the set point.
The additional thermostats may have been added by the previous owner. Can you determine what they are connected to? Maybe they control outlets for portable electric heaters.
You need to explore the system to determine if you have a heat strip or a heat pump supplying the ceiling heat. To see if it is the furnace providing the floor heat, go outside and see if warm air is coming out of the furnace exhaust.
Your tstat should have electric and gas heat positions as well as A/C. The gas is ducted in the floor and the electric is an element in the A/C roof top unit. You can use either but not at the same time. The gas will give you a greater amount of heat....the electric is only like a chill remover.
