Cala Touch KNX T, KNX Room Controller with Temperature Sensor, pure white RAL 9010
All measured values can be used for the control of threshold value-dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multifunctional modules change input data as required by means of calculations, querying a condition, or converting the data point type. In addition, an integrated manipulated variable comparator can compare and output variables that were received via communication objects.
Integrated PI-controllers control ventilation (according to humidity or CO2-concentration) and/or heating/cooling (according to temperature), depending on the respective model.
Cala Touch KNX features a touch display that shows various display and control pages depending on the individual configuration. There is one page available that shows the current measured values, a menu area to adjust device settings and pages with touch control elements for internal temperature control, for light (manual switching or dimming), for shades or windows (manual operation). The integrated timer is a useful helper in everyday life.
Cala Touch KNX is supplemented with a frame of the switch series used in buildings, and thus fits seamlessly into the interior fittings.
Description
- Colour touch display with display and operating pages for - 1× display of current measured values - 1× display of bus data (4 universal spaces) - 1× temperature control (incl. mode change, indication whether heating/ cooling active); can also be used as an extension unit for operating another controller - 3× drive operation (shading, window) with buttons, slider, position display (incl. slat position) - 3× switching or dimming of light (with percentage display) - 1× RGB light control - 1× light color temperature setting - 1× HCL control (adaption of light color temperature over adjustable periods of time) - 1× scenes (4 scenes with recall, storage, status indication) - weekly timer switch with 8 periods - 2× info page (each displays 2 text objects) - device settings
- Screen saver (clock, clock/indoor/outdoor temperature alternately, off) may be switched on or off
- Key tone may be switched on or off
- 4 inputs for binary contacts or T-NTC temperature sensor.
- 8 AND and 8 OR logic gates each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output from each gate can be configured optionally as 1-bit or 2 x 8-bit
- 8 multi-function modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type
- 4 manipulated variable comparators to output minimum, maximum or average values. 5 inputs each for values received via communication objects
- Summer compensation for cooling systems. A characteristic curve matches the target temperature in the room to the external temperature and sets the minimum and maximum target temperature values
- Measuring the Temperature with a mixed value calculation. The share of internal measurement value and external value can be set as a percentage
- Threshold values can be adjusted per parameter or via communication objects
- PI-controller for heating (one or two-level) and cooling (one or two-level) according to temperature. Regulation according to separate set points or basic set point temperature. Fan coil control
