Auxiliary Boards
Two AUX boards, AUX Board A (address 84) and AUX Board
B (address 85), are installed in each unit. Each of the AUX
boards has a set of jumpers, JP1 and JP2, which must be placed
on the "P" terminal and as shown in Fig. 20. The AUX boards
respond to commands from the Carrier Controller module and
send the Carrier Controller module the results of the channels
they monitor via the LEN. See Table 9 for AUX board A and B
DIP switch settings. See Tables 10 and 11 for a list of inputs and
outputs for the AUX boards.

Table 11 — AUX Board B Inputs and Outputs
NOTE: Fan A and B stage outputs are only used on STANDARD TIER
units, identified by the 10th position in the model number. Position 10 is
S and Position 13 is -, 1, 3, or 5.
