Low Evap Pressure
Hold=XX.Xpsi
Unload=XX.Xpsi
The LowEvPrHold (Low Evaporator Pressure Hold) and LowEvPrUnld (Low Evaporator
Pressure Unload) have the same default value of 59 psi. If two compressors are running, the
LowEvPrUnld is in effect and the lag compressor will be shut off to unload the unit. If one
compressor is running, the LowEvPrHold is in effect and the lag compressor is prevented
from starting, thereby holding the unit capacity.
The last action to take place is the shutoff of all compressors running when the
LowEvPrStop setting is reached (default is 58 psi). Reducing these time intervals will
increase detrimental compressor cycling. It is recommended that these settings not be
changed.

Evap Freeze (the unit freeze protection shutdown) is actually a stop alarm and shuts off the
unit when the LWT reaches 36F. It is cleared by going to the CLEAR ALARM menu in
the ACTIVE ALARM hierarchy.
