2.1.2 VARC Control Application
The built-in VARC control application supports the
following features:
• Selection and sequencing of up to six chillers
• Selection and sequencing of one Chilled Water Pump
(CWP) and one or more Sea Water Pumps (SWP)
• Selection and sequencing of up to six electric heaters
• Sequencing of devices for run time equalization
• Alarms and interlocks
• Load shedding
• Troubleshooting help
Sequencing for chillers, pumps, and heaters is the order
in which they start up and turn off. Sequencing is based
on run time, which is the amount of hours a specific
compressor, pump, or heater has run.
The VARC is factory programmed with the options
enabled for that system. Although the system offers
flexibility, these options can be enabled only by a factory
representative. Users can select Normal, Econo, or
Boost mode operation in a single-stage configuration.
