6.8 REMOTE SINGLE EVAPORATOR WITH CASE EEPR – CONFIGURATION H
The S3C case controller is capable of controlling and monitoring single temperature, single evaporator refrigerated fixtures
installed as a line-up. The case shown in the diagram below is the lead case of the line-up. In this scenario, one S3C case
controller is required. The S3C case controller will control all case functions as well as take all the desired sensor inputs and
drive the EEPR. The typical control method is to regulate the discharge air temperature of the evaporator with the EEPR while
allowing the TEV to control superheat. That the required liquid line solenoid (LLS) may be installed as one-per-case or one-
per-line-up. Case numbers 2, 3, 4,…n will require their own S3C case controller as well.
To configure the S3C control package for configuration H
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
