Table 7: Display only fields
Field/LED name Description
Discharge Temperature
Displays the temperature of the refrigerant in its gaseous state at
discharge of the compressor as it travels to the condenser.
% Full Load Amps Displays the percentage of full load amps being used by the chiller.
Current Limit Setpoint Displays the current limit setpoint in percentage.
Chilled Liquid Temperature -
Leaving
Displays the temperature of the liquid as it leaves the evaporator.
Chilled Liquid Temperature -
Entering
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 to
20mA, 4 to 20mA, 0 to 10VDC or 2 to 10VDC input in Analog Remote
mode, PWM signal in Digital Remote mode, E-Link Gateway 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 - Entering
Displays the temperature of the liquid as it enters the condenser.
