Thermostats
I am trying to rig up a programmable 7 day t-stat to be able to have my heater turn on before I get home from work.
I have a duo Therm Comfort Control t-stat in my 5th Wheel. I have 4-wires.
Red= +12 volts
Black=
Green=
Yellow=
I found that I have 12 volts between the red and the green. I touched those together and blew out a fuse in the overhead A/C. After replacing it, I measured +12 volts between them. After trying to touch the +12 volts to the black or the yellow wire I could not get any response from a/c or heater. I am guessing this is a totally different system than a house type system. Since I can not find a programmable stat to replace it with, so I was wondering if could have a programmable battery run the Duo Therm, by making and breaking the +12vt supply? I could set up the Duo Therm for 70 degrees and then make and break the + 12 volt supply to the Duo Therm. Does anyone think this is feasible? Will the Duo Therm hold its temperature after power is removed and restored?
