Description
The
Sensor with Cala KNX display
for the KNX bus system measures various am-
bient 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 switch-
ing outputs. States can be linked via AND logic gates and OR logic gates. Multi-func-
tional 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 commu-
nication objects.
Integrated PI-controllers control ventilation (according to humidity or CO
2
-concentra-
tion) and/or heating/cooling (according to temperature), depending on the respective
model.
Cala KNX
features a touch display that shows various display and control pages de-
pending 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 dim-
ming), for shades or windows (manual operation).
Cala KNX
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 pages for device settings, measuring
values, controls of 1x heating/cooling, 3x light, 3x drive (shading, window)
•
Screen saver (clock, off) and 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
Cala KNX AQS/TH functions (no. 70603, 70608):
•
Measuring the
CO
2
-concentration
of the air, the
temperature
and
air
humidity
(relative, absolute), each with
mixed value calculation
. The share
of internal measurement value and external value can be set as a percentage
