Technical Bulletin—TC-9100 Universal Controller
The cooling symbol on the room command module is displayed when the
output of Programmable Module 2 is greater than 5%. Therefore
Programmable Module 2 must be configured as the main cooling
controller for the room.
The window symbol on the room command module is displayed when
either DI1 or DI2 is configured in Item TCS2 (85 Hex / 133 Decimal) for
the Window Open logic mode and the window contact signals that the
window is open.
The Configuration Index 1 (ALG Item 83 Hex / 131 Decimal) determines
the range of the set point in the room command module and whether 3-
speed fan speed override is available. Refer to Table 25 below.
The TM-9180 can only be used to set the operating mode of the controller
when the operating mode is not being set by a supervisory system. A
supervisory system always has priority over the TM-9180 module. No
special configuration is required for setting the operating mode or for the
use of the Time Scheduling feature, but a room command module with
Programming mode must be ordered.
Note: When the TM-9180 Room Command Module is connected to the
TC-9100 Universal Controller, the three jumpers (JP3) on the
controller board must be set to the left positions.
The configuration parameters TM-9180 Room Command Module are
listed below.

There are a number of dynamic parameters generated by the controller
which can be viewed on the SM-9100 for diagnostic purposes. They are
not available for monitoring by supervisory systems from Johnson
Controls. Refer to
Appendix 1 - Table 1: Item List,
Items 9D/157, A7/167,
and A8/168 for details.
