Art. No. SC 1000 KNX
Functions of the integrated room temperature controller
-
Various operating modes can be activated: Comfort, Standby, Night and Frost/heat
protection
-
Each operating mode can be assigned its own temperature-setpoints (for heating and/or
cooling).
-
Comfort extension possible using presence button in Night or Frost/heat protection mode.
Configurable duration of the comfort extension. Display of the time still remaining in comfort
mode, after comfort extension through the presence button, on the room temperature
controller page.
-
Operating mode switchover via 1-byte objects according to the KNX specification or using
up to four individual 1-bit objects.
-
Status feedback telegrams (also KNX compliant) can be configured.
-
Frost/heat protection switchover via window status or by automatic frost protection.
-
Operating modes "Heating", "Cooling", "Heating and cooling" each with or without
additional level. The temperature setpoints for the additional level are derived via a
configurable level offset from the values of the basic level.
-
Various control types can be configured for each heating or cooling level: PI control
(permanent or switching PWM) or 2-point feedback control (switching).
-
Control parameter for PI controller (if desired: proportional range, reset time) and 2-point
controller (hysteresis) adjustable.
-
Automatic or object oriented switch-over between "heating" and "cooling".
-
Deactivating the feedback control or the additional level possible using separate 1-bit
objects.
-
Internal and external temperature sensor for room temperature measurement possible.
Configurable internal to external determination of measured value and external sensors for
room temperature measurement. Request time of the externally received temperature
value can be set. The room temperature measurement (actual value) can be adjusted
separately for the internal and external sensor using parameters.
-
The actual and setpoint temperatures can be output on the bus if a configurable deviation
is detected (also periodically).
-
Separate or shared command value output in heating and cooling mode. This produces
one or two command value objects for each level.
-
Normal or inverted command value output configurable
-
Automatic transmission and cycle-time for actuating output configurable
-
Command value limit possible.
-
Clipping mode (response of the controller to command values = 100 %) can be set.
-
Setpoint temperature limit possible in cooling mode. If necessary, the controller limits the
setpoint temperature to specific values and prevents an adjustment beyond statutory limits.
-
Fan controller can be operated with up to 8 fan levels.
General functions
-
The device has a master button on the touch sensor surface outside the display area
W
.
The master button can be linked to any KNX channel. In this way, a function, such as the
switching of room lighting, can be executed quickly and easily without touch operation of
the display pages. Two other sensor buttons
V
(scroll) /
U
(return to the start page) make
it easier to navigate through the display pages and can be used alternatively for finger
operation of the graphic interface.
-
The device has a brightness sensor that measures the ambient lighting locally. The
determined brightness value can be compared with a configured limiting value. If values fall
below or exceed the limiting value, it is possible to transmit a switching telegram to the bus.
-
A timer can optionally be activated. The timer, which is integrated in the device and can be
configured using the ETS and via a special timer display page, has up to 8 switching times.
The switching times affect KNX channels (1...30) configured in the device and can handle
the data formats switching (1 bit), value 1 byte (incl. brightness value and position setting)
and value 2 byte and similarly transmit telegrams to the bus.
-
Different settings can be made available to the Administrator via a password-protected
system page (setting of time and date, password assignment, activation of KNX
programming mode).
