Installation & Wiring
E-BUS to WSHP-X Module Wiring
The WSHP-X Module connects to the E-BUS Distribution Module us-
ing a modular HSSC cable. The WSHP-X Module requires a 24 VAC
power connection with an appropriate VA rating.
The E-BUS Distribution Module connects to the VCM-X WSHP Con-
troller, VCM-X Expansion Module, SA Controller (Dual Water Circuit
only), SA Expansion Module (Dual Water Circuit only), or 12 Relay
Expansion Module using the I
2 C port. See Figure 5 on page 8 and
Figure 7 on page 12 for wiring.
Any E-BUS Module can be connected to each of the four E-BUS Dis-
tribution Module’s output ports or can be daisy-chained together using
HSSC cables.
If using a spliced terminal connection for longer runs, one module can be
connected to the E-BUS Distribution Module and any additional modules
would be daisy-chained to the fi rst module. For more information, refer
to the E-BUS Distribution Module Technical Guide.
VCM-X WSHP E-BUS or SA E-BUS
Controller to WSHP-X Module Wiring
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 on page 10 and Figure 8
on page 14 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: Contact Factory for the correct HSSC cable length
for your application. Cables are available in 1/4, 1/2,
1, 2, 3, 4, and 5 Meter lengths and 100 and 150 Foot
lengths.
WARNING: Be sure all controllers and modules are
powered down before connecting or
disconnecting HSSC cables.
Addressing
When the WSHP-X Module is connected to the E-BUS Distribution
Module, set the WSHP-X Module’s address to 1. Set the address con-
secutively for each WSHP-X Module you are using.
NOTE: Address zero defaults to address 1.
