E-BUS Controller to One Condenser Head Pressure Module Wiring
VCM-X Modular E-BUS or VCM-X WSHP
E-BUS Controller to One Condenser
Head Pressure Module Wiring
Up to (2) One Condenser Head Pressure Modules can be daisy-chained
together and connected to the E-BUS Controller using a modular HSSC
cable. The One Condenser Head Pressure Module requires a 24 VAC
power connection with an appropriate VA rating. See Figure 4 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: Contact Factory for the correct HSSC cable length for
your application. Cables are available in ¼, ½, 1, 2, 3,
4, and 5 Meter lengths and 100 and 150 Foot lengths.
