Product and Applications Description
The Dual Sensor AP 254/02 provides ambient light level and
outdoor temperature values. These values can be sent onto the
The device offers four universal channels (A, B, D, E) and one
solar protection channel C, which evaluate light level and tem-
perature for their configured function.
Each universal channel alternatively provides the following
threshold switches for control of switching, dimming, and solar
protection actuators based on ambient light level and/or tem-
threshold switch for light level
threshold switch for temperature
threshold switch for light level and temperature combined
Dependent on whether the threshold condition is met or not
met a corresponding telegram is sent onto the bus via the as-
sociated channel objec
t. Additionally, a
second object can be
activated as required to send a second telegram.
Each universal channel can be deactivated by an associated
blocking object. For each universal channel if a light level
threshold is applied it may be set to the current light level via an
associated learning object.
Additionally, the device
provides a solar pr
otection channel for
automatic control of solar protection equipment. The automatic
control can be started and stopped via a object (sun control ) or
via a dusk/dawn ambient light level threshold. Up to three light
level thresholds control the position (height and angle of slats)
of the solar protection blinds.
The light level thresholds may
be set by sending a bus telegram
to an associated learning object. The solar protection channel
can be deactivated by an associated blocking object.
