The Cala Touch KNX CH room controller for the KNX bus system measures various room climate values. The indoor sensor can receive external values via the bus and process them with its own data to create total values (mixed values, e.g. room average). All measured values can be used to control limit-dependent switching outputs. The states can be linked using AND logic gates and OR logic gates. Multifunctional modules change input data as required by calculating, querying a condition or converting the data point type. In addition, an integrated manipulated variable comparator can compare and output values received via communication objects. Integrated PI controllers control ventilation (according to air humidity or CO2 concentration) and/or heating/cooling (according to temperature). Cala Touch KNX CH has a touch display on which various display and operating pages are shown depending on the individual configuration. There is a page with a display of the current measured values, a menu area for setting up the device and pages with touch controls for the internal temperature control for light (manually switch or dim) for shading or windows (manually move). Cala Touch KNX CH is supplemented with a frame from the range of switches used in the building and thus fits seamlessly into the interior design.
