I’m working on adding a 7500W electric heater to my garage, and wondering how to hook up an external double pole thermostat.
Dyna-glo 7500-watt Electric Garage Heater Wiring Diagram
What gives me concern is that of the double pole thermostats that I have seen they have an amp rating that is lower than the amp of my electric heater at 220V.

So my guess is that the double pole amp rating is for users who have in-line / series connected power to their electrical heating devices, but still want a graphical display?
Since the thermostat is double pole, shouldn’t I worry about the current running through the thermostat?
My interpretation of the wire diagram and purpose of the system, is that my external 220V double pole thermostat will be powered from L1 and L2 at 220V with 100mA or any lower power (ie powered front end with display with buttons ) and then I hook the “load” from the thermostat to 1 & 2 which then switches the heater thermostat and the turn dial is set to max temp on the unit?
What I’m thinking is that lines 1 and 2 would be like 14 awg, and only bring a small current to the switch to activate the furnace thermostat to turn on?

Am I wrong? Will my double pole thermostat run ~ 31.5A and should I look for a heavier duty thermostat? (I understand if you have a simple baseboard heater and you put a thermostat in series with what you are currently running on your thermostat).
I was really expecting to see four wires on the outside section of the thermostat with L1, L2, 1, and 2. When I open the oven backplate do I see four wires or do I have to splice the 14 awg to L1 and L2 in a way. ?
Am I really not here anymore? (Yes, I also want to convert 220V to 24V DC and add a third Nest thermostat to the house, but first I’ll make sure I understand the original purpose of the wiring here!).
The electronic line voltage thermostat on your heater will work if you wire it as shown in the heater wiring diagram, because that arrangement only provides one leg of the line to the thermostat location, leaving the thermostat without proper way to restore own operating power. back to the source. You need to bring L2 to the thermostat box as well as the L1 side load wire that connects to the heater return, which requires running 14/3 from the heater to the thermostat, or just use an electromechanical thermostat. an electronic. The good news is that the thermostat doesn’t transfer much power, however, so the wattage rating isn’t critical.

In the wiring diagram, the large and small boxes marked KM are parts of a relay that carries the full current for the coils, whatever voltage line the thermostat is able to carry current from the control circuit.
The thermostat can be wired with a #14 as the instructions that are part of the UL listing allow it. I think there are some internal fuses/fuselinks not shown in the diagram.
I’m not familiar with the entire Nest product line, you either need a model with a different voltage control or you need to build one.

I have two of the ProFusion Heat Ceiling-Mount Shop Heaters, 25,590 BTU, 240 Volts, Model # HA24-75M that I purchased from Northern Tool earlier this year for my 3 car garage. I’m having a bit of trouble figuring out how to wire the external thermostat to the units. Here is the wiring diagram provided in the manual:
Dimplex Euh08b24ct Almond 7500 Watt 25,590 Btu Electric Industrial Heater With Built In Thermostat
According to the manual, I can wire an external/remote thermostat to the terminal station provided using >16 AWG wire. Does this mean I can use a smart thermostat that runs on 24 volts (think Nest or Ecobee) or do I need a line-voltage thermostat (240 volts). Since this is a 7500-watt heater, should it be a 40-amp line-t or is that why there is a contactor coil on the heater? Just a little confused as to what size thermostat to use…the manual here doesn’t give much on what to use: https://www.northerntool.com/images/downloads/manuals/44740.pdf
This appears to be a line voltage thermostat. I don’t see any transformer in the one line drawing. If you use a 240 volt relay with 24 coils and then a 24 volt transformer you can use a low voltage tstat.
I have read many reviews for this product (ProFusion HA24-75M) and noticed that some indicate that the Fan will run as long as the Unit has power. I have two and both turn off once the Thermostat setting is satisfied. I suspect if a particular unit does not shut down completely there is a problem with the equipment.
Second add one to the Boat: As mentioned, I have two units, have had one for ~2 years and the other was purchased on December 17′. The newer ones have a toggle switch on the back of the Unit to indicate installation with an external Thermostat. This would make it easier to have temperature control at a precise height but the manual does not indicate in any way the Type/Model of Thermostat to be installed? I called a support number but never got through to someone. I tried the disabled one which just closes the contacts but that didn’t work. Anyone had any luck installing an external Thermostat on this heater model?

It’s a bit hard to tell from the diagram. Why don’t you call the manufacturer or installer and get a coltage reading?
The diagram shows the external thermostat wiring as a voltage line. get a 24v coil relay and use an external thermostat (you need a 24V output transformer to power it of course).
I have the same heater. Get a voltage line thermostat wire to flip the switch on the back of the heater and you’re done. If you want to use a programmable t-stat you need a 24volt transformer and a contactor to operate that heater. I got my line volt t-stat from MSC for a little over 50 bucks shipped. With almost every heater I’ve seen I’m stuck they all have their own stat.

How are you I am new to the board and would like to revive this thread. I just bought one of the Profusion 7500 watt heaters this week. I put everything together and it works great and yesterday I decided to take things one step further and wire a remote thermostat because it has an option.
This is where my problem started. At first I thought I would need a line thermostat because of the higher voltage and I was wrong. I wired one and it didn’t work. When I checked the voltage output from T1 and T2 in each diagram at the beginning of this thread, the output that comes out is 24 volts! I thought it was great! I just use a low voltage tstat and things should work – well still nothing.
What am I missing here? According to the manual, the internal tstat is turned off and the back switch is flipped to run a remote tstat. After everything I mounted and wired, I don’t want to go back to using the unit’s internal tstat but I can’t figure it out. Any help or insight would be appreciated. thanks
Can’t be 24VAC if you have the exact setup in the wiring diagram. Is your meter an autoranging meter? Maybe it reads 24 mVac and the circuit is open…

Auto-ranging meter. I should have a copy of the manual with me. It’s on the Northern Tool website /images/downloads/manuals/44740.pdf
I think it looks like the box on the diagram titled “contactor coil voltage” must have some current limiting circuitry to use the 16 gauge. It looks dangerous like that. because you still have 40 amp potential in the thermostat.
Thanks for all the replies. At this point I have
