Button Access Description
Local Leaving Chilled
Liquid Temperature -
Range
Operator
This is the range over which an analog signal or a
digital signal (PWM) can reset the Leaving Chilled Liquid
Temperature setpoint above the operator programmed
Base Setpoint. Programmable as either 10°F, 20°F, 30°F or
40°F, with a default of 10°F, it is added to the BASE value to
create a range over which the remote device can reset the
setpoint.
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.
Remote Analog Input
Range
Operator
This setpoint defines, for the control center, the remote
signal range applied for remote reset of the Leaving Chilled
Liquid temperature Setpoint and Current Limit Setpoint in
ANALOG remote mode. If the remote signal is 0 VDC to 10
VDC or 0 mA to 20mA, this setpoint must be programmed for
0 VDC to 10VDC. If the remote signal is 2 VDC to 10VDC or 4
mA to 20mA, this setpoint must be programmed for 2 VDC to
10VDC.
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.
