Description Default
Condenser Freeze Protect 34.0°F
Evaporator Freeze Protect 34.0°F
Low Evaporator Pressure 29 psi
High Condenser Pressure 140 psi
Evaporator Trip Time 1 sec
Changing setpoint below 28 psi minimum requires glycol to be added to the system otherwise there is a risk of freezing the evaporator.

Sets the value of condenser saturated temperature below which the condenser pump is forced
ON - occurs when unit is off and chiller senses need to provide flow to address a chiller limit
alarm - see "Table 23: Critical Alarms" on page 48.
Sets the value of evaporator saturated temperature below which the evaporator pump is forced
ON - occurs when unit is off and chiller senses need to provide flow to address a chiller limit
alarm - see "Table 23: Critical Alarms" on page
Sets the evaporator pressure value below which the compressor is shut down - may need to
be lowered if glycol is added to the system. If Glycol Enabled is selected, minimum may be set
as low as 20 psi.
