Modular room control
Modular bus transceiver module and flush-mounting actuator
A key feature of the GAMMA instabus is its uniform bus transceivermo-
dule. The bus transceiver module (BTM) can be used as a stand-alone
unit, as well as a combined version in various devices of the flush-
mounting actuator range.
Implementation of the BTI interface (Bus Transceiver Interface) with
the bus transceiver module (BTM) ensures maximum flexibility and an
impressive range of functions. Bus coupling units (BTM) and flush-
mounting actuators with integrated bus transceiver modules (BTM)
enable the use of GAMMA display/operator interfaces, such as push-
buttons, text displays, room temperature controllers and operation
units in a wide range of designs. Thus, all GAMMA instabus operator
interfaces with BTI interface in the design lines i-system and DELTA
style can be combined with either a bus transceiver module (BTM) or a
flushmounting actuator with bus transceiver module (BTM).
This reduces planning work and facilitates installation and commissi-
oning. The application programs of the flush-mounting actuators are
identical to those of the functionally equivalent devices from the mo-
dular room control range. This means that all devices have the same
application program - regardless of mounting type - whether flush-
mounting, with or without mounting frame - or whether designed for
installation in the Room Control Box and Control Module Box.
Modular system for function-oriented installation of room automation
Siemens is the only company marketing a complete range of products for room automation and offering the highest flexibility when it comes to
selecting the type and place of installation.
