EEPR Temperature control selected.
1. Single case in line-up with single
evaporator. One DA sensor
connected to S3C Case Controller:
EEPR moves to calculated “fault”
position.
2. Multiple cases in line-up and /
or multiple evaporators with DA
sensors: Average temperature value
from remaining available sensors is
used for control.

No Suction Pressure Transducer
detected on Left Evaporator (S3C
Case Control pressure input).
2 or 3 Evaporators with multiple
suction pressure transducers
installed in case.
Superheat Control using EEV
selected. Number of evaporators in
case greater than 1. Sensor must be
detected on initial power up to enable
alarm. Pressure Transducer(s) not
connected, miswired or faulty.
Superheat Control selected.
1. EEV closes to prevent possible flood
back.
2. Pressure Sharing Enabled: Average
pressure value from remaining
available pressure transducers is
used for superheat calculation.
