The Ice Box Thermostat was made specifically for use with the Ice Box system. As temperatures change, this unique thermostat will speed up or slow down most fans accordingly by controlling a single plug outlet. Its photocell allows day and night settings, and it has a 6' temperature probe. It keeps fans at an idle when the desired room temperature is met during ?lights on" cycles to prevent heat buildup above the plant canopy, and turns them off during the ?lights off" cycle to keep it from getting too cold. The Ice Box Thermostat can run multiple fans up to 6A.
