6.22 WALK-IN SINGLE EVAPORATOR WITH EEV AND EEPR – CONFIGURATION V
The S3C case controller is capable of controlling and monitoring walk-in coolers and freezers equipped with electric
defrost. For a single coil walk-in with an EEV and EEPR, one S3C case controller and one S3C valve module are required.
In the scenario detailed above, the typical control method involves controlling return air temperature (box temp) with the
EEPR and controlling superheat with the EEV. As with all evaporators equipped with an EEV, a liquid line solenoid (LLS) or
suction stop solenoid is optional as flow through the evaporator can be stopped by closing the EEV.
To configure the S3C control package for Configuration V
shown above, follow these directions:
If the controller has not been factory set, then upon initial
start-up, the controller will be in set-up mode and the screen
will display
