1. INTRODUCTION
MasterCella is the new electronic controller for static or ventilated refrigerating units, able to manage all the actuators normally featured, such as:
compressors, fans, defrost, alarms and lights. The MasterCella case is IP65 and the electrical wiring is especially simple, due to the fact that the front panel
can be removed. The MasterCella case allows installation either on the panel or on the wall.
