Propane thermostat vs. True-Air electronic thermostat

[John_Canfield]

The last couple of weeks was the first time we had a chance to use the heat on the coach. What exactly is the reason for having a manual Suburban thermostat which I assume calls for propane heat, or the True-Air electronic thermostat which also can control the propane furnace?

John,
The manual thermostat is for the seperate bedroom heater. You have 2 propane heaters the largest is controlled by the digital True -air. the rear heater is contrlloed by the manual thermo.If you are using the electric heat and demand more then a 3 degree change the gas heat will start automatically along with the electric until the temp requested is met at which point the True-air system will swich back to electric heat only, to maintain that temp/

But, you may find that one LP gas heater will not keep up in a very cold situation. Especially with the extra cubic space of the 40AD.

Therefore you have two propane heaters.

I know this cause I have only one LP heater and have been in very cold enviroments.

John & Steve - thanks! I looked through the Horizon manual before asking my question, and to my surprise there was no mention about the other thermostat.

Jim - the Suburban manual thermostat is mounted in the OnePlace center, the TrueAir thermostat is mounted above the galley sink on the end of the overhead cabinet.

I have been wondering what the round plastic vents were for in the aft cabin - there is one in the head, and one just aft the head door. Maybe they are for the auxillary heat.

>>EDIT<<

Whoopie - now I know what the 'mystery' three round plastic duct outlets are for! It is for the small bed/bath propane furnace. Now we will be toasty warm at bath time (not to mention that it doesn't sound like a 747 half-way through the take-off roll.)
