Hot Gas Bypass Screen PID Tuning
Screen
This screen displays and allows adjustment of the
PID parameters of the hot gas bypass valve.
In almost all situations, the factory loaded PID values
are more than sufficient for operation of the chiller
throughout its entire operation range. It is highly
unlikely changing these parameters will be required;
however, if such changes are required only do so
under the direction of a factory Customer Service
person. Improper adjustment of these values can
negatively influence the performance of the chiller.
To adjust a parameter, touch the parameter to
display the input numeric keypad on the screen.
Enter the new value and touch the enter button.

Freezestat Setup Screen
This screen displays and allows adjustment of the
Freezestat settings.
The Freezestat is a freeze protection safety that shuts
down the chiller if the coolant temperature gets to
cold. This safety protects the chiller from damage
cause by freezing water in the evaporator. This is a
critical fault alarm. The chiller cannot start until the
coolant temperature is at or above the Set Point
temperature plus the Cut In temperature. To adjust a
temperature, touch the temperature to display the
input numeric keypad on the screen. Enter the new
value and touch the enter button.
