The controller operates in standalone mode when it is not connected to a
supervisory system via the communications bus nor to a TM-9180 Room
Command Module. In standalone mode the controller may operate in one
of three control modes:
• COMFORT (occupied): control at comfort set point
• STANDBY (unoccupied): control at a standby level set point
• OFF (not in use): low limit control only
The control modes are set by the window contact and occupancy sensor
inputs, and may be modified by the occupancy button on the Room
Command Module as shown in Table 1.

When connected to a supervisory system via the communications bus or
to a TM-9180 Room Command Module, the controller may operate in
COMFORT, STANDBY or OFF control modes, and additionally in
NIGHT mode:
NIGHT (scheduled unoccupied): control at a night level set point.
The control modes are set by the supervisory system or TM-9180, and are
modified by the occupancy sensor input and occupancy button on the
Room Command Module as shown in Table 2. The window contact input
always switches the controller to OFF control mode, and a MANUAL
mode is available from the supervisory system to inhibit the action of the
occupancy sensor and occupancy button.
