Understanding the basics

A line voltage thermostat is typically used with our electric wall or baseboard heaters. Low voltage thermostats are typically used to control central heating and cooling systems.

Please note: only use a low voltage thermostat with a Cadet heater if:

  • The amperage load exceeds the rating of the line voltage thermostat, AND
  • It’s combined with a relay
  • Double pole thermostats have an "off setting" and break both sides of the heater’s power line.
  • Single pole thermostats only have a "low" setting and no true "off" setting, and break only one side of the heater’s power line.

For heaters with a single pole thermostat, if room temperatures dip, the heater will turn on even if the thermostat is at its lowest setting. The best way to ensure your heater is off is to disconnect power to the heater circuit at the main disconnect panel.

It depends. A built-in control is convenient to install when the walls are already finished. However, a wall thermostat controls the room temperature more accurately, is more convenient to use, and offers a broader selection of models. Electronic thermostats provide more accuracy and can help you save money on your electric bill.

Mechanical thermostats use two pieces of bonded metal that bend as the temperature changes. As a result, the heater is turned on and off within three to six degrees of your set point.

Electronic thermostats use digital temperature sensing for precise temperature control. They monitor room temperature within 1 degree or less of your set point. Select models can be programmed for heating certain times of day or days in a week.

If energy efficiency is important to you, keep in mind that wide temperature fluctuations in thermostats can waste energy. This increases the cost of running your heaters and it actually can make your room less comfortable. Our programmable electronic thermostats can save you up to 28% on your electric heating bill. Over time, this can offset the higher price of the thermostat.

Thermostat frequently asked questions

Sure. To bypass the built-in thermostat, turn the heater’s thermostat to the highest setting, then use the wall thermostat to regulate the room temperature. A wall thermostat is not necessary and should not be used for the CB, Energy Plus or RCP Series heaters

Well, it depends. A built-in control is convenient to install when the walls are already finished. However, a wall thermostat controls the room temperature more accurately, is more convenient to use, and offers a broader selection of models. Electronic thermostats provide more accuracy and can help you save money on your electric bill.

Always mount a thermostat on an inside wall away from drafts, direct sunlight, or any appliances that could affect its temperature reading. Make sure the airflow around the thermostat isn’t blocked by shelves, pictures or other wall décor.

Mount wall thermostats used with a baseboard heater across the room from the heater. It’s easiest to mount a thermostat used with a wall heater in the same stud cavity, on the opposite side of the stud, about five feet above the floor. If you have two or more heaters in a large room, place the thermostat in a central location.

Unfortunately no, but that’s okay. Cadet heaters allow you to quickly warm up the rooms you’re in, instead of the ones you’re not. You can use individual thermostats to easily control the areas you need to heat.

Yes.

We recommend replacing the thermostat. If it feels hot, it may not be working efficiently, which actually decreases its accuracy. Or, it could indicate an overloaded capacity. However, keep in mind that a normal operating thermostat will feel slightly warmer than the room temperature by about three to five degrees.

How do I install my thermostat?

For wall thermostats, please go to the thermostat section and choose your model to find the owner's guides with complete installation instructions.

For step-by-step instructions on wiring a Cadet Electric Baseboard to a wall thermostat, view our How-To Video

BASEBOARD WIRING WITH A SINGLE POLE (2 WIRE) WALL THERMOSTAT - 120V OR 240V SUPPLY

  1. After you have disconnected factory connector A (left side) or factory connector B (right side), proceed to the next step.
  2. Route supply wires to the thermostat wiring box.
  3. Connect one supply wire to one thermostat wire (typically marked L1).
  4. Connect remaining thermostat wire (typically marked T1) to one heater wire.
  5. Connect remaining supply wire to remaining heater wire.
  6. Connect supply ground to grounding pigtail provided.

BASEBOARD WIRING WITH A DOUBLE POLE (4 WIRE) WALL THERMOSTAT - 120V OR 240V SUPPLY

  1. After you have disconnected splice A (left side) or splice B (right side), proceed to the next step.
  2. Route supply wires to the thermostat wiring box.
  3. Connect one supply wire to one thermostat wire (typically marked L1).
  4. Connect remaining supply wire to one thermostat wire (typically marked L2)
  5. Connect one thermostat wire (typically marked T1) to one heater wire.
  6. Connect remaining thermostat wire (typically marked T2) to remaining heater wire.
  7. Connect supply ground to grounding pigtail provided.Refer to the wiring diagram below that corresponds to your heater and thermostat application.
    Note: Wiring diagrams shown below are for reference only. All wiring must comply with the National Electric Code (NEC). See wall thermostat instructions for your specific application.

For best results, use a Cadet wall thermostat or an EBKN end cap DPST thermostat kit. It is recommended that a thermostat be provided for each room. In extremely large rooms where multiple heaters are being used, a Cadet low-voltage thermostat with a relay will give the most comfortable results. The location of the thermostat should be selected carefully. Thermostats should not be located near drafts from an open doorway or within 18" (45.7cm) of an outside wall, or in direct sunlight or unusual heat sources. A television set or appliance that builds up heat near a thermostat will prevent the thermostat from functioning properly. A wiring diagram illustrating typical wiring of the thermostat is included in literature provided with the thermostat, and on a simple diagram provided on the thermostat.

To wire an installed wall thermostat to a Cadet in-wall fan heater:

  1. Route supply wire from wall thermostat to wall can.
  2. Remove a knockout in the wall can and attach the supply wire to wall can with a strain relief connector, leaving a 6 inch wire lead for later use.
  3. Connect supply ground wire to grounding pigtail in wall can.

  4. Turn heater assembly upside down (element down) with motor facing you.
  5. Using wire connectors, connect the supply wires leading from the thermostat to the loose heater wires.

For built-in thermostats on any wall heater, choose your heater model on Cadet's Products page and refer to the owner's guide.
