4.2 Use
Six complementary device types are available which can control HVAC and electric
applications.
•
Room temperature, humidity, and CO
2
content of the room are controlled
according to the demand and to energy efficiency criteria.
•
Four freely parameterizable pairs of touchkeys can be configured for light
switching, dimming, blinds, scenes, sending values, etc.
The sensors in the room operator unit
measure:
– Room temperature.
– Relative room humidity.
– CO
2
concentration in rooms with varying occupancy due to time or number of
people such as in museums, movie theaters, offices, meeting rooms, class
rooms, auditoriums, hospitals, living spaces.
The room operator units
control and operate:
– Room temperature (via PID controller)
– Humidity (via threshold value)
– Air quality (via threshold value)
– Fan stages (independent of temperature, air quality and humidity control
functions)
– Room operating modes
– Input of the occupancy state
as well as
– Switching of electrical equipment
– Switching and dimming of lights
– Control of shading / blinds
– Selecting and saving of scenes
The room operator units with display
show the following information about the
room:
– Present room temperature, outdoor temperature.
– Present room humidity, outdoor humidity .
– Present room air quality .
– State of window contacts
– Device mode (e.g. heating, cooling).
