Description
Displays whether compressor 1 or compressor 2 is the lead compressor.
Separate indication showing whether the digital output from the controls is
commanding motor 1 or motor 2 to RUN.
Displays the motor current as a percentage of the Full Load Amps (FLA) value for
motor 1 and motor 2.
Displays the current limit value in use. This value could come from a 0 to 20 mA, 4
to 20 mA, 0 to 10 VDC or 2 to 10 VDC input in Analog Remote mode, PWM signal in
Digital Remote mode, SC-EQ communications interface in ISN (BAS) mode, or a locally
programmed value.
Individually indicates the total number of hours compressor 1 and compressor 2 have
run.
Individually indicates the total number of times compressor 1 and compressor 2 have

Description
Sets the maximum current draw of the chiller when run in the Local Mode. This is
the total current of motor 1 and motor 2 added together. Adjustable between 30 and
100%, default = 100%.
Sets the maximum current draw of the lead compressor during initial start for the
selected Pulldown Time. Adjustable between 30 and 100%, Default = 100%.
Sets the amount of time that the lead compressor pulldown demand limit setpoint will
be in effect. Adjustable between 0 and 255 minutes, Default = 0 minutes.
