can anyone run me through Drolets instructions on the digital display for a HeatPro? Manual really sucks
 
Trying to hook up a t stat?

Digital display on the back?

Yes, I am hooking up a tstat. Really simple however I am only getting 14 volts coming out of the drolet to the thermostat so stat wont work.
 
shouldn't be anything coming out of the tstat hookup on the heatpro I believe. all that needs to happen is to complete the circuit.

what kind of tstat?
 
you can just put a jumper wire in and it will open the damper. no power needed.
 
Does the tstat have a battery? Self powered if so.
Yes, all the tstat needs to do is "close" the circuit to make the damper open
 
I'm not sure on the HP, but on Tundra 1, if you measured from one of the tstat terminals on the back of the furnace to ground, there would be 24V (probably a bit more actually)...if you measure between terminals it will be less because the other terminal has to go to ground through the damper motor...

Thanks, there was nothing wrong at all. I was using the wrong tstat. I have a round dial Honeywell heat only stat for the wood furnace. For some reason a battery operated stat is required. Not sure why it matters, but it does. lol.

I have an old school mercury t-stat on my Tundra and it works, however, I don't use it anymore.

Yeah running with the tstat is pretty useless...other than using it to bring a load to temp...but honestly the bath timer mod is better for that...tstat works for burning down coals too I guess, but so does the manual switch that comes on the furnace (they still have that on the T2/HP?)
I don't use the tstat on the Kuuma now either...works just fine without it.

I had a t-stat connected at one time- never used it. A spring loaded 60mn timer works so much better, you can't forget about it and will always time out and open the circuit. I was temped to remove the factory switch, but on my install it's pretty hard to get to anyway.

I emailed Drolet to find out some info on the digital display as well as how the variable speed fan part works. Screenshot_2020-05-07-21-16-35.png This is the response i got:

Pressing the - button for a couple seconds seems to access some settings? Anyone messed with this? Sounds interesting....
Also has anyone determined at exactly what plenum temp the different blower speeds are activated? As well as the over temp limit?
I have the Heatmax2 but I'm sure the controls are the same.
