Status
Reading for evaporator superheat is shown on the right display. Press ENTER at
Cd54 to show reading for EEV position (in%) on left display.
Cd55
Discharge
Super Heat
Code Cd55 will display the discharge superheat values in C /F as calculated by the
discharge temperature minus the discharge saturation temperature as calculated
from discharge pressure. “-----” will be displayed if selection is not valid.
Cd58
Water Pressure
Switch/Condenser
Fan Switch State
or Override Logic
State
Code Cd58 will display “CLOSE” if the WPS or CFS switch contacts are closed or that

Pump Down Logic
Code Cd59 allows operation of the pump down logic control. The display will flash be-
tween “STArT PdN” and “PrESS EnTEr”. Once the operator confirms continuation of
the sequence, pump down logic begins. If pump down logic is completed within 20
minutes, the unit will turn off and the display will flash “P dN DOnE” and “SHUT OFF”.
The operator must shut off the unit. If the pump down logic is not completed within 20
minutes, the unit will return to its previous control condition.
