Outside Brightness and Temperature Sensor

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 bus.
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- perature:

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.
