2006 Alpine - Thermostat Help!

[troutmd]

Hello:

I bought a 2006 Alpine 40 FDTS that needed some TLC. I am having trouble with the Hydro Hot system and A/C system.

In the bathroom area, my coach has a 'five button Duotherm' thermostat mounted to the left of the sink area.

Out by the dining table is what appears like a thermostat bracket, but it is 'horizontal' with a phone line coming out (I know the phone lines are used for thermostats in these coaches). The thermostat or whatever goes there was missing and I cannot figure out that kind or what it is.

Does anyone have a 2005 or 2006 coach with Hydro Hot that can send pictures of the thermostats in your coach? Is there one? Two? Are they both the same? Does the HH system have its own?

Thanks for any help provided!!!

The ‘05/6 had 1 thermostat that controlled both the zones of the HydroHot. Zone 1 was the front of the coach, zone 2 was the bath and the bedroom. The thermostat was located next to the tank level meter and the inverter panel in the hallway. There is a temperature sensor mounted on the wall above the driver’s seat for zone 1 and one in the bedroom mounted on the ceiling very near the A/C unit for zone 2. Power for the thermostat comes from the front A/C unit.
Unfortunately about 5 years ago my original thermostat failed so pictures of mine will not do you any good. Post pictures of what you have and maybe we can help you further.
