Installation & Wiring
E-BUS to Water Source Heat Pump
Module Wiring
The Water Source Heat Pump Module connects to the E-BUS Distri-
bution Module using a modular HSSC cable. The Water Source Heat
Pump 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, or 12 Relay Expansion Module
using the I
2 C port. See Figure 4 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.
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 Module is connected to the E-BUS Distribution Mod-
ule, set the WSHP Module’s address to 1. Set the address consecutively
for each WSHP Module you are using.
NOTE: Address zero defaults to address 1.
