Case controller, type EKC 223 and EKC 224

Applications

EKC 223 and 224 are developed for refrigerated plug-in cabinets with one compressor or for remote cabinets
controlling the liquid line solenoid valve. 3 sensors can be connected; Sair, S5 (Defrost termination), and Sc
(Condenser temperature).
The configuration of the relays is done via the parameter "o61 Application mode"
The Table 1 and Table 2 shows the application modes for EKC 224 and 223 respectively.

EKC 224 applications
