Service terminal
Hand-held terminal with three operating levels, easy-to-read display panel and
user-friendly key pad, for commissioning, tuning and servicing of HVAC systems
incorporating controllers in the DESIGO 30 range.
The service terminal is connected to the LON bus, so allowing the user access
(depending on operating level) to the data from the connected DESIGO 30 devices.
The basic procedure for operation is as follows:
Menu and data points are selected using the four navigation keys. Selected points are
displayed in inverse video, and adjustable values can be modified with the + and
keys. Modified values are accepted with

Mounting
The BCS is designed primarily as a hand-held operator terminal. As an alternative, a
bracket is available, which can be screwed onto any surface. The service terminal can
be clipped onto this bracket when not in use. The BCS may, however, also be mounted
in a control panel front, if required. The service cable, which incorporates the LON bus
and power supply, can be plugged into the service socket of a controller.
