Chilled Liquid Temperature - Return
Displays the temperature of the liquid as it enters the
evaporator.
Chilled Liquid Temperature - Setpoint
Displays the active temperature setpoint to which the
chiller is controlling the evaporator liquid. This value
could come from a 0-20mA, 4-20mA, 0-10VDC or
2-10VDC input in Analog Remote mode, PWM sig-
nal in Digital Remote mode, MicroGateway interface
in ISN mode, or a locally programmed value.
Evaporator Pressure
Displays the present refrigerant pressure in the evapo-
rator.
Evaporator Saturation Temperature
Displays the present saturation temperature in the
evaporator.
Condenser Liquid Temperature - Leaving
Displays the temperature of the liquid as it leaves the
condenser.
Condenser Liquid Temperature - Return
Displays the temperature of the liquid as it enters the
condenser.
Condenser Pressure
Displays the refrigerant pressure in the condenser.
Condenser Saturation Temperature
Displays the saturation temperature in the condenser.
Oil Sump Temperature
Displays the temperature of the oil in the sump.
Chiller Current Limit Setpoint
Displays the Chiller Current Limit Setpoint. The Chill-
er Current Limit Setpoint could be from a 0-20mA,
4-20mA, 0-10Vdc or 2-10Vdc input in Analog remote
mode or PWM input in Digital remote mode or Mi-
crogateway interface in ISN remote mode or a Local
Chiller Limit Setpoint entered at the Keypad.
If equipped with software version C.OPT.11.02B.xxx
(and earlier), this setpoint comes into effect during
the Chiller Steady State Period (this period is in ef-
fect after the Leaving Chilled Liquid Temperature is
within 2ºF of the Leaving Chilled Liquid Temperature
Setpoint (Chiller Pulldown Period no longer in effect))
and remains in effect for the remainder of System Run.
If equipped with software version C.OPT.11.03.01.004
(and later), this setpoint is in effect after the Lead
Compressor Pulldown Time setpoint (see below) has
elapsed and for the remainder of system run.
