UI90x
Communicative room unit with CO
Summary
The room unit with CO
carbon dioxide concentration measurement, optional humidity sensor, and
control knob for setpoint control and other settings. The binary output is
controlled either on a remote basis, or as thermostat, hygrostat or CO
The units communicate over Modbus RTU / RS485 and they can be used as open
system components with majority of building control system and controllers.
Compared to the old series UI09x, these types dispose of knob and display blue
backlight function and more accurate sensors.
All versions of the room units now contain relative humidity measurement. UI092
and UI094 versions have been replaced.
Beware of unit terminals connection. It differs from its predecessor.
Application
Function
The units acquire temperature, CO
the room, temperature correction (controlled by the knob) and required operation
status which is set by short push of the knob or in the menu. In the configurable menu
following values can be set and displayed:
