Good Day, The questions of wiring are more specific this depends on the number of heaters on the circuit and their wattage. It is a better question to call in with or specifically what model you are working with and how many heaters so we can help you. The reason is the demand and size so we better understand and keep you out of trouble. Glen Dimplex Customer Experience Team.

Hello, Yes, a single pole thermostat will be a great match for your UC101 heater. No you will not need a master on/off switch before the thermostat

How do I know if I need a single or a double pole.

If you are replacing an existing unit, if you have 4 wires, you need the double pole, if you have 2 wires, you need the single pole. I accidentally ordered the double pole prior to looking at the unit I was replacing. Hope that helps!

WILL THIS PRODUKT WORK ON A SINGLE WALL FURNACE

Asked by MRKLUTCH April 5, 2020

Answer

It should work for 120/240 V. It's a simple thermostat. It connects the relay contacts when the temperature is lower than the set point, and opens when it's warm enough. It may not work for low voltage small gauge wires that go into furnace circuitry.

Answer

Hi Sunwoo, the thermostats we sell are line voltage for our wall heaters or baseboards, the Nest thermostat is a low voltage so you will need additional relays to shut off your floor heater when the temperature is reached, contact the floor heater manufacturer to find one that works with their product.

Hi Chris, the 22A is the most current you can apply to the thermostat before it fails, that being said it would be a max of 240V x 22A = 5280W maximum load of heaters on 240V, or 2640W on 120V.

I have a hard wired 240 volt space heater with no thermostat can this thermostat be wired to control it

Asked by Howie January 28, 2020

Answer

Hi Howie, If you have a Cadet heater a line voltage thermostat would work good, this one can handle up to 22A make sure you don't exceed that max current.

Does this work with celing heat

Asked by Joe January 22, 2020

Answer

It can work with your ceiling heat if the previous thermostat is a line voltage thermostat meaning that it can handle 120V or 240V which would require thick 12 gauge wire, call us if you have questions 855-223-3887.

Almost easy installation with a stupid flaw.
This was almost easy as pie, until I went to screw everything back in place. The Temperature knob is positioned right on top of—almost over the wall mounting screw. So how am I supposed to screw this thing into the wall. There’s no drill bit extender in the world that can do that job. Mine must be defective, since I’m not seeing anything like this in other reviews...?

Hi Andy, I recommend to start with the screw that has wiggle room to accommodate the 2nd screw better, if this doesn't work then you may need to get a different electrical junction box, call us for better assistance 855-223-3887.

It’s a thermostat. It should be part of the hearing device because without it the hearing device doesn’t work properly. But this thermostat is fine. It’s brand new. It is working as it should.
