Leaving Chilled Liquid
Temperature – Setpoint
Displays the present setpoint to which the chiller is operating
whether controlled remotely or locally. This value could come from
a 0 to 20 mA, 4 to 20mA, 0 to 10VDC or 2 to 10VDC input in Analog
Remote mode, PWM signal in Digital Remote mode, E-Link or SC-
EQ communications interface in ISN mode, or a locally programmed
value.
Leaving Chilled Liquid
Temperature Cycling –
Shutdown
Displays the Leaving Chilled Liquid Temperature at which the
chiller will shut down to avoid over-cooling the building.This
value is calculated by subtracting the Leaving Chilled Liquid
Temperature Cycling Offset – Shutdown from the Leaving Chilled
Liquid Temperature – Setpoint. If the value is below the absolute
minimum allowed shutdown temperature, the minimum value is
displayed.
