1.0 Introduction
1.1 General
The OPTYMA™ Control three-phase is a controller for refrigeration systems with a three-phase
compressor or for controlling the three-phase evaporating unit only, for complete cold room
management. Front access to the automatic fuse and motor protector for the compressor and an
innovative design combine to make it the ideal choice for effective refrigeration control.
Applications:
• Complete management of three-phase refrigerating systems up to 7.5 HP static or ventilated, with
off-cycle or electrical defrosting.
