sensor
• 24 Vac, Class II po
wer
In addition to the points
used for the VAV application, the spare inputs and outputs on the UC400
controller may be used for ancillary control and programmed using Tracer TU Tracer Graphical
Programming 2 (TGP2).
Note: For more informa
tion on w
iring spare points, refer to the Tracer UC400 Programmable
Controller Installation, Operation, and Maintenance Manual (BAS-SVX20).
