BCS
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 enter , and functions are terminated with the
esc key.
