Installation & Wiring
VCM-X WSHP or SA Controller to
WSHP-X Module Wiring for Dual
Water Circuit
The VCM-X WSHP Controller or SA Controller communicates with the
WSHP-X Module using the E-BUS Distribution Module. See Figure 7
for wiring details (VCM-X WSHP Controller shown).
Figure 7: VCM-X WSHP Controller to WSHP-X Module Wiring Diagram for Dual Water Circuit
NOTE: When using the WSHP-X Module, all compressors
will be wired from the WSHP-X Module, not the
VCM-X WSHP Controller or SA Controller.
