DR-001 Wall Thermostat 4 wires single or Double poles 120-277V 3360-7756W, White.

Most will be using 10/2 Romex with ground on a 30 amp breaker - this product touts a 28Amp. Rating, a breaker should always protect the wire. The housing of the device is also metal but is ungrounded - it is supposedly isolated. Any variation of temp reading from the unit vs a thermometer can be attributed to wire and device heating instead of actual temperature but the device is accurate.To make this product better use a larger work box (4 gang, grounded if applicable) to disperse the build up of heat from the wires and make the unit more accurate. This product would be better if it came with such an enclosure and I am still dubious to the lack of grounding for the metal encasement but for the price it works I would have paid more for more. I just wish it was implemented better. I bought this to work with a 5kw comfort zone heater and it does what it needs to. Easy to install, don’t cut any strands off the tinned copper and use as large of an enclosure you can to keep it accurate.

The instructions... aren't great. But paired with a Dr. Infrared heater this thing is awesome. I used it with the 7500w model and it's perfect. I use it as the "external thermostat" on that unit. Just know a few things:1) It doesn't "turn off the device" on the lowest setting. What i mean by that is, it will literally trigger the heater based on the set temp and is fully automated. even at the lowest knob setting, it still registers that as a "temp" (even though it says lowest is like 45 degrees) and will trigger the heater to come on. However, this isn't a problem for me. I set it at 50 degrees F and it controls the heater beautifully (cycling it on/off when needed to hold temp). I just keep it on the opposite corner of the garage from where the heater is and it's very accurate.2) You still need to turn your heater on with the remote or on the device, switch the toggle to "external thermostat" and then it works.It's also super accurate from what I can tell. My car thermometer and my regular old mercury one read 50 degrees F when it's set at that. So very nice.

This works and does what it is supposed to. I used it because it is the recommended stat for a Dr. Infrared Garage heater and didn't want to go off the map when first getting it hooked up. My only complaint is the range between on and off. Seems like it takes too long to kick on and then runs too long once it does. Makes the temperature swings pretty substantial. Will probably replace it with something else later on but for now it works fine.

When I got this product it came with absolutely NO protection in the box. just the thermostat box with a shipping label. Horrible packaging.It has been 2 weeks that I had this product and I just walked into my shed and it was like a sauna, 85-90F when I have the thermostat set on 72F which normally kept the shed at 55F. Accuracy was garbage when it did work, now it won't shut off and calls for heat unless the dial is on 'OFF' even when my shed is burning hot.First time I have tried a thermostat other than Honeywell and this will be my last.Also, whoever designed this product is not very smart. I had to extend my wiring. Instead of keeping the Line wires at the bottom like any other themostat, this has one on the bottom and one on top. Doesn't even make sense.0 stars. Do not buy.

GOT THIS TO GO WITH MY OVERHEAD GARAGE HEATER. IT'S A HIGH VOLTAGE THERMOSTAT. I HAD AN ELECTRICIAN COME IN AND WIRE MY SHOP. HE HOOKED THIS THERMOSTAT UP TO MY HEATER. IT WORKS GREAT. I DON'T GET HUNG UP OVER DETAILS SO IF IT'S OFF BY A COUPLE OF DEGREE'S I'LL NEVER KNOW IT. ALL I KNOW IS IT WORKS LIKE IT'S SUPPOSED TO AND KEEPS MY SHOP NICE AND COMFORTABLE. IF YOUR PLANNING ON INSTALLING HEAT IN YOUR GARAGE OR SHOP AND YOU DON'T WANT TO MESS AROUND WITH WIRING CONTACTORS AND RELAYS AND TIMERS. GET ONE OF THESE. THEY SWITCH THE HIGH VOLTAGE SIDE AND ARE VERY EASY TO INSTALL. THANSK

Very effective and safe solution for controlling my garage heater. Would highly recommend instead of a monopole switch or no switch at all (breaker controlled).

The heater works as described. I had an electrician installing a double power line to provide the 240V for the heater. I wish the heater or the thermostat had an explicit on/off switch. Although the off - position locks in at the dial, it would be good to know the heater is effectively off as I use it in an uninsulated garage and I don't want the heater to be under power in any way if the thermostat dial knob isn't effectively turned all the way to the off.

I purchased this thermostat because it was recommended when purchasing the Dr. Heater DR966 240-volt Hardwired Shop Garage Commercial Heater, 3000-watt/6000-watt, DR966 240V. Install was strait forward with easy to follow instructions.
