Section 4
PRESSURE
PRESSURE is used to view/change the chiller's high and low pressure fault and warning
settings and set a delay time. If the chiller exceeds the fault setting it will shut down, the con-
troller will display a fault message and, if enabled, sound the alarm. If the chiller exceeds the
warning setting the chiller will continue to run, the controller will display a warning message
and, if enabled, sound the alarm. The delay sets the length of time needed after a pressure
fault before the chiller shuts down.
Note Since the controller can only display six lines at a time, keep pressing the down arrow
until the High P Delay and Low P Delay lines are visible.
If a change to the setting is needed, press the arrows to highlight the desired pressure and
then press the enter button. The highlight will flash. Press the up or down arrow to change
the value. Once the desired setting is displayed press enter to accept the change and stop the
flashing.
Note You cannot set the High Warning value higher than the High Fault value. You can-
not set the Low Warning value lower than the Low Fault value.
When the desired changes are made press the left arrow, or esc button, to return to the
SETTINGS display.
