DISPLAY ONLY FIELDS
Displays the temperature of the refrigerant in its gaseous state at discharge of
the compressor as it travels to the condenser.
This displays the percentage of full load amps utilized by the system.
Displays the current limit value in use. This value is percent of Input Full Load
Amps.
Displays the temperature of the liquid as it enters the condenser.
Displays the temperature of the liquid as it leaves the condenser.
Displays the temperature of the liquid as it enters the evaporator.
Displays the temperature of the liquid as it leaves the evaporator.
Displays the programmed temperature setpoint for leaving chilled liquid. It is the
local value or remote reset value depending on control source.

(condenser minus evaporator). Only appears when Head Pressure Control is
enabled
Displays the active Head Pressure Setpoint to which the head pressure is being
controlled. Only appears when Head Pressure Control is enabled
