Functions
Room
Command
Module
The controller can be connected to a Room Command Module, from
which it receives the room temperature, the remote set point and other
override signals. The TM-9180 intelligent Room Command Module
provides these signals via a serial bus connection to the controller. The
other Room Command Modules (TM-9150/9160/9170) provide the
signals as individually connected physical inputs to the controller. In
addition, an NTC temperature sensor is available for mounting within the
FCU.
For installations without a Room Command Module, the controller is
available with an integrated set point adjuster. Alternatively, the remote
set point and fan override controls may be incorporated into a custom
FCU control panel. Refer to the Specifications and Technical Data
section of this bulletin for details of the components required.
