Siemens room unit QAA822
The room unit is supplied from the connected controller through 2-
wire interface (low voltage, SELV).
The room unit must be connected to the Climatix controller by two-
wire twisted pair cable. It is possible to use unshielded conductors.
 The device is suitable for semi-flush mounting with a recessed
installation box.
 The device must not be mounted into recesses, shelves, behind
curtains or doors or above or near the direct heat sources.
 Avoid direct sun and draught.
 The conduit must be sealed on the device side as an air stream
along the conduit can affect the sensor readings.
 The permissible ambient conditions for mounting the device must
be observed.
 The mounting instructions are enclosed with the device.
Local installation regulations must be observed.
The equipment is not protected against accidental connection to
AC 230 V.
After interruption of the connection to the 2-wire interface, the
