The control wiring (analog inputs/outputs, digital inputs/outputs and relay outputs)
is made on the following terminal blocks of the Electronic Control Board CC9
(refer to location in figures 3.7, item 3.2.2).
XC1: Digital and Analog Signals
XC1A: Relay Outputs
The following diagram shows the control wiring with the digital inputs as active
high as set on factory (jumper between XC1:8 and XC1:10).
