- Unit controller unit controller is installed as standard it can be used to modify unit set points and check control parameters a built in display shows chiller operating status plus temperatures and pressures of water refrigerant programmable values set points a sophisticated software with predictive logic selects the most energy efficient combination of compressors and eexv to keep stable operating conditions to maximise chiller energy efficiency and reliability the unit controller is able to protect critical components based on external signs from its system such as motor temperatures refrigerant gas and oil pressures correct phase sequence pressure switches and evaporator the input coming from the high pressure switch cuts all digital output from the controller in less than 50ms this is an additional security for the equipment fast program cycle 200ms for a precise monitoring of the system floating point calculations supported for increased accuracy in pressure temperature conversio 4
