Technical Bulletin—TC-9100 Universal Controller
7
•
NIGHT (scheduled or manually set unoccupied): LED off,
•
OFF (room not in use):
LED off.
The Operating modes are set by the supervisory system and are modified
by the Window Contact and Occupancy Sensor inputs (if configured),
and by the occupancy button on the room command module, as shown in
Table 3. The Window Contact input always switches the controller to
OFF mode, and a MANUAL mode command from the supervisory
system overrides the action of the Occupancy Sensor and occupancy
button.

Depending on the way that the controller is configured, the COMFORT,
STANDBY, NIGHT and OFF modes may change the Working Set Point
(WSP) of any control module, and the OFF mode may be configured to
override the output of each control module to close off the heating,
cooling, or air flow devices.
For further details, refer to the subheading

under the
Programmable Module Configuration
section of this

Supervisory systems available from Johnson Controls include the
NCM 311/361 in the Metasys Network System, the CS-9105 Control
Station, and the Companion System.
Note: A supervisory system which is setting the operating mode of the
controller will have priority over a locally connected TM-9180
Room Command Module.
