Aw. electronics are just electricity with smalle numbers.
My new A/C is actually a heat pump - the thermostat works on heat and cooling. However, the manufacturer warns, it won't suffice when the outside temp falls much below 40 F. Not a problem for me, I seldom go anyplace colder than that, and it works fine then. I have an electric heater as well, should I need it.
I also have the original SolAire, but the one time I fired it up, it smelled of buring propane, so I shut it off. It will sit unless or until I pull it, disassemble it, and have a real good look at the heat exchanger. I usually have a BWD alobng to keep my feet warm at night anyhow.

Subject: [GMCnet] DuoTherm Heat Strips...Thermostat?
My late model DuoTherm rooftop AC has the heat strips installed. When I turn it to heat it runs and blows warm but never shuts off even when the coach gets quite warm. Is there supposed to be a thermostat function supplied by the 'cooler/warmer' knob on the unit?
If not, has anyone wired up a 110V thermostat to the heat strips? Years ago, I used a 110V thermostat in a home grown hot water heating system I built and it would be a simple matter to make one work in this case. I can do electricity...electronics not so much. 8o :lol:

Kerry,
I installed a heat strip in our other coach several years ago. It had a plug to hitch the heat strip up and of course the heat position on the switch, but it appeared to be an on and off issue with our DuoTherm unit. I am going to look at the AC unit wiring diagram and see if it is in the thermostat loop.

No, it is not controlled by the thermostat. That controls the cooling only.

Thanks Emory. I'd like to use the heat strips when I don't really need much heat. For instance when it gets down to 40 or so at night. If I'm in a campground, I'd think I'd rather use their electricity than my propane. Plus, I'd rather not hear the furnace come off and on all night.
Is there a simple way to splice in a thermostat? Either a line voltage model or something else?
I know where the plug is that goes to the strips because the first time I tried them I got nothing. The PO told me the plug had probably vibrated loose and it had. I now have it taped together so it won't vibrate loose.

It should be fairly easy to splice in a thermostat. You would just put it in series with one of the leads to the heat strip. HOWEVER it would have to be a 120volt thermostat with contacts heavy enough to handle approx. 15 amp Here is one from Home Depot that should work:
http://www.homedepot.com/Building-Materials-Heating-Venting-Cooling-Thermostats-Nonprogrammable/h_d1/N-5yc1vZbay4/R-202247917/h_d2/ProductDisplay?cata logId=10053&langId=-1&storeId=10051#.UKvOHKVanbA
You would also have to use fairly heavy gauge wiring. At least 16 gauge and 12 would be better.
It probably would be easier to use a relay in the air conditioner which has a 12 volt coil that has contacts that will handle the 120 volt load. Then you could use light gauge wire to a wall mounted thermostat using a 12 volte source for the relay.
I have a heat strip and have used it but I can tell you that if it is freezing outside the heat strip really doesn't need a thermostat as it would run all the time anyway. So I seriously question the need to install a thermostat on it. I am sure that was the feeling of Duotherm when they designed the heat strip for the air conditioner. It will take the chill off but it won't be enough heat to keep the GMC at a typical comfortable temperature when it is cold outside. It puts out the same amount of heat as a typical 1500 watt portable electric heater.

Don't assume the Duo therm strip heater is not tied to the units thermostat. Check the wiring schematic to be certain. I'm sure Emery would know if his is or isn't but I can tell you my Duo therm strip heater is in fact connected to the same thermostat that also controls the cooling. I have a mid 80's Duo therm that looks a lot like the original units except it doesn't have the 3rd control knob. It was a factory accessory add on kit that I installed and the factory thermostat had the connections that were there If a strip heater were to be added, the existing switch for fan,cool off also has a connection for the strip heater but you need to scribe the heat position. The fan operates the same as it does in cool mode it does not cycle with the thermostat. I always use my cube heater and turn on the strip heater if I need more heat as the fan is quite noisy even on low and you need to feel the air to tell if the thermostat has cycled off.

Well, that is interesting. Mine is definitely not controlled by the Thermostat. I have a 15,000 btu Brisk Air high efficiency which I bought in 2006.
Roy, if you have a wiring diagram for yours that would be interesting to see if mine is either hooked up wrong or leads can be changed to operate it through the thermostat. Mine was factory installed.
You say that yours was an 80's model. I had installed a heat strip years ago in my original 1977 Duotherm but it required a new switch as there was no position for a heat strip (no terminal either). I also had to modify the case to fit it in.
So, perhaps your 80's model is different from the 2000's models?

Emery I am going out of town for Thanksgiving and won't have time to check the schematic but a couple of years ago I found a new old stock factory strip heater kit for $20 that looked like it would fit my unit so I bought it. The instructions showed how to install it an wire it. The fan switch had the necessary terminals and the thermostat had the necessary terminals that were needed to connect the kit. I did not have to replace anything just hook up the strip heater inside the unit. I guess they saved fifty cents by not adding a few contacts to the newer controls.

Emery, couldn't I just break the appropriate wire going into the connector. When I unplug it, the strips don't work so I'm assuming there is a relay internally somewhere. I don't have a schematic but it is a Brisk model also.
I'll look into finding a schematic.

If there is power going to the strip heater plug very likely the little metal fuse is blown these fuses are temperature rated it is located inline with the strip heater wire. To check it use your ohmeter also check the heater the same way. Remember if the A/C thermostat is also controling the strip heater you need to turn it warm rather then cold also the fan switch needs to be in the heat mode my Du therm (sun chaser) has an unmarked spot for the strip heat position because it is an add on unit.

Well, I've got the strip in My DuoTherm as well, and, as folks have determined, it isn't controlled by the thermostat, only on/off. But, the blower is so noisy when I run it, I can't possibly imagine leaving it on at night. I'm looking for an electric heater I can build in that will be safe and won't be too noisy. Any recommendations?

I'd suggest looking at Lowe's or Home Depot or an
electrical supply store for an electric wall heater
for bathroom use. I'd suggest installation in the
door for built-in vacuum cleaner (Palm Beach and
others) or a plain wall beside entry door. That
would give you a couple of feet of clear space in
front of the heater. You'd probably want to get one
with a blower and/or variable heat and blower speed
capabilities.
If you don't want to do an actual install, West
Marine has a nice heater that sits on the floor and
is not very tall (maybe 4" maximum) high. Even in
its shipping box, it stows in space not much bigger
than a shoe box. It has at least two heat and two
fan settings and blows out along the floor. Since
my coach has NO furnace, I will use electrical to
keep the worst of the chill off of the interior in
the unlikely event that I go out when some heat
might be needed.
If you use ANY portable unit (other than one of
the oil-filled radiator type) be sure that you get
one that has a tip-over safety switch that will cut
the juice to the heater element if it tips over.
