This PCA contains a firmware chip that holds base instructions for the operation of the unit.
LEDs are provided to alert the technician during diagnostics, regarding POS problems,
processor function, or reversed polarity of the two-wire system feed wires.
The board receives +14 VDC from the Hydraulic Interface PCA. Customer programmable and
5-button preset as well as the Manager Keypad (except for ATC) are connected directly to this
PCA. It supplies +5 VDC to the Hydraulic Interface PCA.
