and cooling functions;
Automatic switching of the operating modes through presence sensor or window contact;
Weighted average of two temperature values;
Dew-point temperature computation;
Temperature regulation (measured and setpoint, as °C), relative humidity (measured and setpoint in
percentage), air quality as TVOC concentration, in ppb, and CO

Design
The device is realised for wall-mounting on either round or square wall box with distance between fixing holes
of 60 mm, or rectangular flush-mounting box (3 slots, italian standard) with distance between fixing holes of
83,5 mm.
The multisensor is equipped with a metallic support for mounting, that can be also ordered separately if
necessary. A plastic adapter and a terminal block for KNX bus line are also included in the package.
