DUAL CHILLER PUMP CONTROL FOR SERIES
CHILLER APPLICATIONS — Pump control for series chill-
er applications is controlled by the master chiller only. The
control of the slave chiller is directed through commands emit-
ted by the master chiller. The slave chiller has no action in
master/slave operations. The slave chiller only verifies that
CCN communication with the master chiller is present. See the
Dual Chiller Sequence of Operation section on page 68.

CCN Control
Night Time/Low Noise Operation —
fortLink™ controls have the ability to lower the sound level of
the machine by reducing the number of fans that are running,
provided that the conditions are acceptable. Reducing the num-
ber of running fans also limits the capacity. Three parameters
must be configured for this operation. A start and end time for
the mode of operation is required and an optional capacity limit
set point must also be configured.
