VCC-X Controller Inputs
The VCC-X Controller is designed with 8 analog inputs, 4 analog
outputs, 8 binary inputs and 8 relay outputs.
There are also 2 E-BUS Expansion Ports which allow the use of
communicating sensors and the E-BUS Modules.
See Figures 6 & 7 for wiring details. Detailed wiring for all inputs
and outputs are found on the pages that follow.
