The ducted split wine cellar cooling system has several different options available.  The available electric heater is a factory-mounted option that will protect your wine cellar from cold ambient temperatures. A standalone humidifier is a necessary addition if the wine cellar consistently sees low relative humidity (RH) levels. Lastly, Wine Guardian’s remote monitoring and sensing system allows the user to place up to three (3) remote sensors in the wine cellar to monitor average cellar conditions at different locations in the cellar (near the ceiling, near the floor, etc). This information is continuously relayed to the cooling unit and to the remote interface controller.
