WSHP-X Module
Technical Guide 10
Installation & Wiring
VCM-X WSHP E-BUS or SA E-BUS
Controller to WSHP-X Module Wiring
for Single Water Circuit
The WSHP-X Module connects to the E-BUS Controller using a modular
HSSC cable. The WSHP-X Module requires a 24 VAC power connection
with an appropriate VA rating. See Figure 6 below for wiring.
Any E-BUS Module can be connected to the E-BUS Controller’s E-BUS
port or can be daisy-chained together using HSSC cables.
NOTE: When using the WSHP-X Module, all compressors
will be wired from the WSHP-X Module, not the
VCM-X WSHP E-BUS Controller.

WARNING!! Observe Polarity! All
boards must be wired with GND-
to-GND and 24 VAC-to-24 VAC.
Failure to observe polarity could
result in damage to the boards.
