VISONIK

BPS communication with TEC™

Function sheet

Terminal equipment controllers—short TEC—are communicative individual room

controllers. They can be linked to form a system via the floor level network (FLN).

If a VISONIK system is used for higher room management, the building process

station (BPS) server as the communication master (FLN master). AEROGYR

ventilation controllers RWI can be integrated in addition to TEC devices.

The TECs control and supervise the temperature or humidity of individual rooms. The

RWI controllers help control ventilation plants. Both device families can communicate

with the BPS via FLN (equipped with COM2 communication card). The BPS as the FLN

master coordinates the individual devices and integrates them in the higher

management station.

FLN master

The FLN master carries out the following tasks in addition to controlling and supervising

communication on the floor level network:

Task Examples

Provide information for users Operating mode, setpoints for heating and cooling,

present room temperature, etc..

Coordinate TECs Form TEC rooms and groups, calculate, transmit

operating values, etc..

Support RWI RWI data points, higher functions.

Allow for service action Enabling, valve purge, etc..
