System Wiring

NOTICE

Do not connect any of the SW+ (13,9,5,1) and SW- (16,12,8,4) pins together, either directly or via a switch closure. Doing so will create a short circuit condition which will disable and potentially damage the controller.

NOTE: On an AC controller (p/n 24B596), the J7 strip is line (input) voltage but the J6 strip is all 24VDC. On a DC controller (p/n 24B59‘), the J6 and J7 terminals all carry the input voltage.
