TRUCLIMATE 300 WATER-COOLED CHILLER WITH HYBREX TECHNOLOGY INSTALLATION MANUAL - Formerly the WC Hybrex Chiller
Chiller Plant Controls Wiring
Wiring Procedures
• The differential pressure sensor pressure range
need to match the DIP switch settings in the
sensor controller. The adjustment can be made
through the Primary Unit HMI.
• Use 20AWG wires size for wiring the temperature
sensors and differential pressure sensors.
• The harness with all temperature inputs terminates
in the back of the unit near the bottom header.
Use crimp connectors to joint the temperature
sensor wiring and the primary unit harness.
