OVERVIEW
This screen gives a general overview of common chill-
er parameters for both refrigeration shells.
DISPLAY ONLY
Discharge Temperature
Displays the temperature of the refrigerant in its gas-
eous state at discharge of the compressor as it travels
to the condenser.
Chilled Liquid Temperature - Leaving
Displays the temperature of the liquid as it leaves the
evaporator.
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 signal
in Digital Remote mode, MicroGateway interface in
ISN mode, or a locally programmed value.
Evaporator Pressure
Displays the present refrigerant pressure in the evaporator.
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.
