Do All Cadet Thermostats Have A True Off Setting?

Not all Cadet thermostats have an actual "off" setting. There are two types of thermostats based on the off setting. Read the descriptions below.

Single-Pole 

It is a single pole if you cannot see "off" displayed on the thermostat. It has no true "off" setting. Instead of "off," it only has a "low" setting.  If you turn to the leftmost of the dial, it will only maintain the lowest temperature.

It automatically shuts off and turns on when it reaches certain temperatures. This type breaks on one side of the heater's power line. 

Double-Pole

In contrast, you can see "off" on a double-pole thermostat. You can turn it off by turning the dial counterclockwise on the thermostat's panel to the leftmost, where the OFF sign is.

Unlike the single-pole, this type breaks on both sides of the heater's power lines. 

If there is no OFF sign on the panel, you can check how many wires are at the back of the thermostat. If it has 2, it is a single-pole, while a double-pole has 4.

After using the thermostat for some time, it will encounter problems. One problem is when the thermostat does not turn on. You will only see a blank screen on the display panel.

  • Weak or dead batteries
  • The main power source is defective or has no power
  • Circuit breaker malfunction
  • HVAC system problems

When the thermostat turns off suddenly, the settings remain when you turn it back on.

If the thermostat doesn't turn on, below are the solutions:

  • Replace old batteries
  • Ensure the thermostat receives enough power
  • Replace faulty circuit breaker
  • Check and fix the HVAC system

If you cannot fix the issues, ask a professional for assistance.

Why Does The Heater Run And Then Turn Off?

It can be annoying if the heater that your thermostat controls works and then turns off unexpectedly. 

According to Cadet, the heater won't turn on because it detected abnormal temperatures. Also, the sudden stop is due to the wrong voltage connection.

Another reason why the heater turns off is the thermostat settings. You may observe that the heater is cycling every 15 seconds. If that is the case, you should update the thermostat settings. 

If you have a digital thermostat, here are the solutions suggested by Cadet:

  • For the TH401 model - change the heating cycle from "Std" to "Fan."
  • For the TH106 model - change the factory setting to the ON position

For non-digital thermostats cycling less than 5 minutes, the cause is the wattage inside the room provided with heat. 

Refer to the owner's guide for detailed troubleshooting instructions. If you need further assistance, contact the Cadet technical support team.

Should You Set The Thermostat To Auto Or On?

With the thermostat, you have the option to adjust the fan settings. Whether you keep the fan setting on or auto is a matter of preference. You can use any of the settings depending on your family's needs. Read the distinctions of the settings below.

On

If you set the thermostat to ON, it runs the fan constantly. Some advantages of this setting include:

  • Distributes air inside the home evenly
  • Better air filtration and flow
  • Less stress on the heater's fan

However, you might spend more on this option. You also need to replace the air filter often, which adds to your expenses. Sadly, the constant heat can make your home colder in the winter.

Auto

On the contrary, setting the thermostat AUTO will only work when the HVAC cycle starts. Once the cycle is over, the thermostat automatically turns off.

With the AUTO setting, you can save on energy and air filter replacement costs. Besides the cost savings, you will benefit from superior dehumidification during summer.

The major disadvantage of the setting is the absence of air circulation when it is off. Other downsides of this setting are less air filtration and faster wearing out of the fan. 

Both settings have their pros and cons, so it is up to you which to use for certain times of the day.

In Summary

It is easy to turn off a Cadet digital thermostat. On the touch panel, press both + and - simultaneously. Then, press the M or - buttons four times until the standby icon appears. The icon will blink slowly to signify that the thermostat is off.

There are various Cadet thermostat models, so it is best to refer to the product manual for instructions.
