24V Thermostat Conversion Kit

Introducing our new 24-volt thermostat conversion kit for WhisperKOOL split systems!

Utilize industry-leading technology from major manufacturers to monitor the environment of your cellar. (See individual thermostat manufacturers’ websites for details.)

  • Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet or laptop.
  • Monitor run time and energy usage.
  • Set alarm notifications.
  • View your cellar conditions from your mobile device.

The use of the 24-volt thermostat conversion kit eliminates the thermostat normally included with the system and allows your contractor to select, purchase and install the thermostat technology of your choice, including but not limited to Nest, Ecobee, and Honeywell.

By selecting the 24V Thermostat Conversion Kit, you have acknowledged that the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. You will have to source and purchase your own 24V thermostat to run the equipment.

  • Not utilizing the thermostat from WhisperKOOL also eliminates the use of the bottle probe.
  • WhisperKOOL does not provide smart thermostats.  Those must be purchased separately.
  • WhisperKOOL customer service staff do not provide technical support for customers’ selected thermostats.

Great Product

It is as advertised. I have my house renovated and added a cellar. Not sure which type I need at first just wondering down and asked questions. That's why I am very thankful to your customer support which is very responsive and patient with me. I am very happy with this cooler. Thank you!


I was looking for a quiet cooling unit and saw this one. I checked it out and look at the reviews. Good thing I bought it in this website. They are very friendly and helpful. Also, the website is very easy to use.


It is cool that it doesn't make any noise like what I had before

great product

It didn't take too long to install it. Also, it doesn't take too much space
