Description
The
Room Controller Cala Touch KNX CH
for the KNX bus system measures va-
rious ambient climate. Via the bus, the indoor sensor can receive external values
and process them further with its own data to a total value (mixed value, e.g. room
average).
All measured values can be used for the control of threshold value-dependent swit-
ching outputs. States can be linked via AND logic gates and OR logic gates. Multi-
functional modules change input data as required by means of calculations, query-
ing a condition, or converting the data point type. In addition, an integrated mani-
pulated variable comparator can compare and output variables that were received
via communication objects.
Integrated PI-controllers control ventilation (according to humidity or CO
2
-concen-
tration) and/or heating/cooling (according to temperature), depending on the re-
spective model.
Cala Touch KNX CH
features a touch display that shows various display and con-
trol 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 (manu-
al switching or dimming), for shades or windows (manual operation).
Cala Touch KNX CH
is supplemented with a frame of the switch series used in
buildings, and thus fits seamlessly into the interior fittings.
Common features in all models:
•
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
Cala Touch KNX AQS/TH functions (no. 70821, 70823):
