PRODIGYT M2 UNIT CONTROLLER
The unit controller software can directly access a unit by plugging into the M2 board phone jack and connecting to a serial
port using a PC converter. Any unit on the same daisy−chained network can be adjusted from any unit M2 board or the NCP.
A LAN ethernet converter and phone modem are also available for remote connections.

Add the weights for each control description to determine option.
Weight− Description
1− GP1 board present, DIP set to VAV mode for VAV or CAVB con-
trol action.
2− VAV control action. 0 for CAVB control action. See table 29.
The following weights are used for VAV:
4− PID control when smoke detected. 0 for staged
8− PID control when running ventilation. 0 for staged.
16− PID control when running cooling. 0 for staged.
32− PID control when running heating. 0 for staged
For VAV control action, either PID or staged control can be selected.
For CAVB control action, PID is automatically used. (Staged is not
available for CAVB). Configuration alarm will occur if GP board (W/
DIP set to VAV) is installed and at least one of the following ECTO
parameters value are not set to non−zero: ECTO 0.01, 0.23 or 8.16
