Button Access Description
Local Leaving Chilled Liquid
Temperature - Setpoint
Operator This value allows the user to define the Leaving Chilled Liquid Temperature
that is to be maintained by the chiller. It is programmable over the range of
38.0°F to 70.0°F (water) or 10.0°F to 70.0°F (brine). If Smart Freeze is enabled,
the range is 36.0°F to 70.0°F (water).
Leaving Chilled Liquid
Temperature Cycling Offset -
Shutdown
Operator This value allows the user to specify the Leaving Chilled Liquid Temperature
at which the chiller will shut down on a LEAVING CHILLED LIQUID – LOW
TEMPERATURE cycling shutdown. This is done by defining an offset below
the Leaving Chilled Liquid Temperature setpoint. It is programmable over a
range of 1°F to 64°F.
Leaving Chilled Liquid
Temperature Cycling Offset -
Restart
Operator This value allows the user to specify the Leaving Chilled Liquid Temperature
at which the chiller will restart after a shutdown on a LEAVING CHILLED
LIQUID – LOW TEMPERATURE cycling shutdown. This is done by defining
an offset above the Leaving Chilled Liquid Temperature setpoint. It is
programmable over a range of 0°F to 70°F.
Local Input Current Limit Operator Allows the user to specify the maximum allowed chiller input current (as a
percentage of FLA). When the chiller input current reaches this value, the
input current override takes effect.
Pulldown Demand Limit Operator Allows the user to specify the current limit value (as a percentage of Full Load
Amps) to which the chiller will be limited during the specified pulldown limit
time. This value will override the Input Current Limit value during this time
period. This function is used to provide energy savings following chiller start-
up. Pulldown demand limit is ignored in BAS (ISN) control source because the
BAS system is expected to use its algorithms to reset current limit as required
in that operating mode.
Pulldown Demand Time Operator Allows the user to set a period of time for which the pulldown demand limit
will be in effect after the chiller starts.
Print Operator Generates Setpoints print report.
