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.

Doing a good job

Very happy with the performance so far. Did a fast job of getting my cellar to the right temp.

Ralph Houkom
Exactly as advertised

The unit appears to be what it is advertised to be, aesthetically handsome, fairly quiet, and easy to install. It hasn't operated a lot yet as it's a back- up unit. Overall, very satisfied.


Works great in my closet type cellar. Very easy to operate

Michael Lawrence
Nice cooler but very noisy

Installed in an under the stairway cellar. Cools nicely but very noisy in the living space.

My father is happy

I installed a wine cellar in my parent's house secretly when they where on a cruise. When they came back my dad is so happy


I've been using this cooling unit in my small cabinet sized wine cellar which is located on my living room. It does the job. Maintains the temperature
