TRUCLIMATE 300 WATER-COOLED CHILLER WITH HYBREX TECHNOLOGY INSTALLATION MANUAL -
Formerly the WC Hybrex Chiller
Operation and Connection
Chiller Plant Startup Procedure
Operation and Connection
With a DDC device the chiller may be controlled by a build-
ing management system. The DDC device can work over
several different commination protocols (BACnet MSTP is
standard). DDC devices can be customized to relay an array
of refrigeration, electrical and water information about the
chiller. The User Management interface supports multiple
users wich allows you to assign different levels of accessibil-
ity to different users. Default (Adjustable) Parameters:
• Mac Address - 42
• Protocol - BACnet MSTP
• Baud Rate – 38400
Unit Startup
•
High voltage is correct and matches nameplate.
•
Low voltage and controls wiring is complete.
•
Piping is complete, and the water system has been
cleaned and fl ushed and no water leaks are present.
•
Air is purged from piping system.
•
Isolation valves are open and water control valves.
•
Pumping system is fully operable.

PSI = Pressure drop in pounds per square inch
HC = Heating Capacity in MBTUH
HE = Heat of Extraction in MBTUH
kW = kilowatt
ft hd = pressure drop in feet of head
HR = Heat of Rejection
BACnet Connection
The BAS will land a single shielded twisted pair cable (22
gauge) to the RS 485 card on the HydroLink2 Aurora.
•
Service/access panels are in place.
•
Transformer has been switched to lower voltage tap
if needed (208/230 volt units only).
See unit schematic for details.
•
Ensure that a chiller startup sheet is complete for
each chiller.
