This ’02 Winnebago Journey has a heating and cooling system comprised of three main parts and a couple others not considered main: (as I compose articles for each one, the links will be underlined)
- True Air thermostat Model 6535-344*; (system controller – retired, see #2)
- Micro-Air EasyTouch RV ASY-356; (Smart thermostat, replaces #1)
- Coleman Mach 6535a-871 Heat Pump; (supplies Cool or Warm air as required)
- Coleman Mach 46515-611 Heat Pump; (Replaces the 6535)
- Suburban Gas Furnace Model SF-42; (Aux propane furnace for rapid and powerful heating)
- Miscellaneous heating & cooling items such as filtering and venting.
- Damage in shipment warranty replacement heat pump
I’m treating these components as separate for the sake of clarity but they all work together in an integrated fashion. And the first three are dependent on consistent and appropriate voltage from both the battery system, and the AC system; shore power or generator power. Other then mentioning the voltages occasionally where important to the articles, I won’t delve into those voltage supplies. Check other sections of this blog for that sort of thing.
