TUC
GENERAL INFORMATION
A Terminal Unit Controller (TUC) is a remote mounted electronic
controller which is generally used to control individual pressure
dependent VAV fan powered boxes, VAV cooling only boxes, heat
pumps, etc. If your ECC/WCC II system has TUC’s, a Sat II-A is
required to allow the TUC’s to interface with the front end ECC/
WCC II computer.
To set up a TUC, you must fi ll out a TUC Set-Up Screen along with
an Analog Input Screen and EA Driver Screen.
The SAT II-A is seen as 4 satellite controllers with each satellite
controller having up to eight TUC’s. For example, if you have a
SAT II-A addressed #4, it will be seen as satellite controllers #4, 5,
6 and 7. TUC’s 1-8 will be seen through the screens for satellite #4,
TUC’s 9-16 will be seen through the screens for satellite controller
#5, TUC’s 17-24 will be seen through the screens for satellite #6,
and TUC’s 25-32 will be seen through the screens for satellite
controller #7.
For example, assume that the SAT II-A is named #4, and you
would like to set up the screens for TUC #20. TUC #20 would be
seen through Analog Input Screen #4, Control Output Screen #4,
and TUC Set-Up Screen #4 on satellite #6.
