The Hold and 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.
