F while reducing the excess relative humidity to the proper 50 to 75 BREEZAIRE cooling units are designed to lower the temperature while removing only excessive moisture In a properly constructed enclosure this process can raise the relative humidity The unit does not add moisture to the enclosure The unit does not include a heating system and will not warm the enclosure The WKC Series is not intended to cool service cabinets which are maintained at lower temperatures and opened or entered frequently The cooling unit comes with two 2 optional thermostat systems Mechanical or Digital Electronic Sentry IID The mechanical version is low profile and will blend in with the casing of the unit The mechanical version is of a simplest design and the adjustments requires a 1 4 straight type screwdriver The Digital Electronic Sentry IMI thermostat adds additional safety to your enclosure and has the following features Large easy to read green LED display Accurate easy to adjust no tools needed readable set points with continuous reading of enclosure temperature or displaying of set point when changing enclosure temperatures Power outage protection which delays unit start up after power outages Blocked airflow protection which shuts down unit and protects wine in case of high temperatures caused by condenser blockage Controls temperature by enclosure air sensors or optional bottle probe The configuration of the units
