SenseAir tSENSE VAV User manual

CO2-, temperature- and
relative humidity transmitter
General
tSENSE VAV for wall mounting measures indoor air carbon dioxide concentration, temperature and
relative humidity in rooms. tSENSE VAV is available with colour touch display (LCD).
The unit connects to Direct Digital Control (DDC).
Linear outputs are pre-programmed as CO2-, temperature- and relative humidity transmitter.
Measuring ranges can be modified via touch display, from PC (Windows) software UIP (version 5 or
higher) and USB communication cable, alternative via Modbus or BACnet.

Automatic system test
A full system test is executed automatically at every power-up. Sensor probes are checked constantly
during operation against failure by checking valid dynamic measurement ranges.
System checks returns error bytes to RAM. Error codes are available by connecting the sensors to a
PC with a special USB cable (art.no. 00-0-0070) connected (see fig. 2). Error codes are shown in
software UIP (version 5 or higher) and in the display at “Meter status”
