WhisperKOOL offers a Cold Weather Start Kit designed for their split-systems where the condensing unit will be installed in cold climates. WhisperKOOL split systems are designed to be adaptable to almost any install, and the standard condensing unit was built to operate with exposed temperatures between 20° F and 110° F. However, there are some territories that may have outdoor temperatures that drop below 20° F. The WhisperKOOL Cold Weather Start Kit is the solution for these cold weather locations.

How it works:
When the outside temperatures drop, the pressure in the standard system drops as well. The system operates using a pump down cycle and a low pressure switch to turn the compressor on and off. When the temperature drops below 20° F the pressure in the system is too low to start the compressor. The use of an electronic bypass is needed to start the compressor and temperature controlled heaters installed on the receiver are needed to raise the pressure in the system to optimal levels. The Cold Weather Start Kit will bypass the low pressure switch on startup and keep the pressure in the system high enough to operate correctly for environments as cold as -15° F.
It is important that the cooling system stays operational during cold weather conditions, as heating the house using the central HVAC system will indirectly increase the temperature of the wine cellar. This kit will ensure that the cooling system will continue to operate efficiently in cold weather environments to maintain an optimal wine storage temperature.
