The Chilled Water Master Controller (CWMC) is our premiere chiller control.
The CWMC is the brain that controls the individual Digital Diagnostic Controllers, (DDC), on a multi-staged chiller. It manages all cooling and heating functions for each chiller stage, as well as operation of the seawater and chilled water pumps. It optimizes compressor operation by automatically changing the lead compressor to evenly distribute run time. The CWMC monitors chiller operating status as well as all safety protection systems.
DDCs can and do stand-alone as a single stage or multi-staged chiller controls. The addition of Pump Relay Panels (PRP) and remote DDC switches are necessary when not using the CWMC.
