PostBy: mlchelp On: Mon Oct 04, 2010 4:33 pm

Purachased the Super Mag last year and it worked great, I have been reading alot about the Coal trol and being Im lazzy and like evrything automatc I was wondering If the Coal Trol will work on the Super Mag and if it would do any good, Alot of comments I have read say that the new Harman control on the Super Mag works about the same as the Coal Trol, Comments please! Im new to burning Coal so Im not an expert by any means.

We did have a few customers install on Harmon Magnum stoves, but no one that I know of has installed on one of the new super mags as far as I know. Chances are it can be installed on it. The wiring used for the older magnum would probably be a good starting point.

As for it "doing any good", that depends entirely on what you find lacking on the controls you have. :) I don't know what changes Harman made to their controls for the super mag, so I can't really give you a bullet point list of differences, unfortunately. If you can give us some idea of what you're not happy with I'll let you know what we do so you can make a decision.

Also, we do have a 90 day money back guarantee if you aren't satisfied with the Coal-trol, so you could give it a try and decide if you want to go back to your old controls or not.

Thanks for the reply, it has 3 knobs one for feed adjustment with test and then 1 -6, one for temperature or stove temp 50 - 90 for room temp or 1 - 7 for stove temp and then the last knob has 5 positions, off or L room temp or High room temp and then low stove temp or high stove temp. My feed knob is set on 3, I couldn’t get a straight answer on this one from the dealer or Harman but they said no lower than 2, I was getting hot coals falling off the burn grate into the ash pan so I did set this back some. I have the 2nd knob set on 75 and it stays pretty close to this temperature + or minus 2 degrees, but there are times when the stove really starts going and it gets hot in the room and takes a while for the stove to settle down and the temperature to drop back down to a comfortable level. The third knob I have set on room temp and the high or low controls the distribution fan speed. It comes with a short temperature wire that always falls down and I think this may be causing the flare ups. Im really new to this and don't really like having to jack with all these controls. If the coal trol can make all this automatic for me in a more traditional thermostat type of device that would be great. All 3 motors have standard household plugs on them, there is also a esp sensor that measures the flue temp but I’m not sure exactly what that does. How does the unit save coal, does it learn the optimal feed, blower, distribution rate to maintain the temperature I set, what about lowering the temp at night etc? The controls on this unit just allow me to set the temp and leave it, no night and day etc.

I put a coal trol on a regular mag, and it worked great. The esp sensor on yours is supposed to go in another room I think, not on the flu. I believe it is supposed to sense temp in another area before the controls do so it can ramp up and help avoid over shoots(I could be wrong though). I will say the coal trol does work well on keeping the temp maintained at your set point. As for temp set backs I think it is a waste for a solid fuel heater like a small stoker, as it seems to use more coal to warm back up then you saved. That was my experiance and I think others experinced it as well. Now maybe not so bad if you only drop one or two degrees but then whats the point.
I did like the fact that it would ramp up the feed rate slowly rather then just going full bore, you could probably remove your controls and just plug your motors in.
Good luck, Eric
