SCREENS
CONTINUED
Status screens include:
Temperature
Displays the To Process temperature and the Setpoint tem-
perature. To change the Setpoint temperature, go to
Changing Setpoint Temperature, in the Operation section.
From Process Temp
Shows the temperature of the fluid entering the chiller. Can
display in degrees Fahrenheit or Celsius.
Percent chiller load
Shows the current percent of chiller capacity being used.
This percentage is a read-only value and changes as the
chiller cycles.
Water level
Displays the current water level status. Screen displays
Level Okay, or Level Low. If the level is low, see Filling
the Chiller, in the Installation section.
Compressors (for units with dual compressors, 20 ton+)
Displays the activation status of the two refrigeration cir-
cuits, compressor 1 and compressor 2. ON is activated;
OFF is disabled. Lists In/Out of Service for each.
Refrigerant suction pressure
Shows the status of the refrigerant suction pressure in PSIG
for compressor(s) 1 and 2, if chiller has dual compressors.
NOTE: Typical refrigerant suction pressure is between 55
PSIG and 95 PSIG.
Refrigerant Discharge pressure
View the status of the refrigerant discharge pressure in
PSIG for compressor(s) 1 and 2, if chiller has dual com-
pressors. Typical discharge pressure is between 190 PSIG
and 325 PSIG.
Percent Ethylene Glycol by Volume and
Low Temperature Cutout
Displays the percentage of ethylene glycol or propylene
glycol solution (by volume) in the chiller in degrees
Fahrenheit. Changing the percent glycol automatically
changes the low temperature cutout.
