Brightness Threshold Switch; Ad Calibration Value - Niko SWISS GARDE 300 Applikationsbeschreibung

4.2.4. OBJECT 7 INPUT - HVAC - FORCED CONTROL
Input 2 Bit
Object 7 "Input - HVAC - forced control" is identical to object 3 "Input - light - forced control".
4.2.5. OBJECT 7 INPUT - HVAC - DISABLE
Input 1 Bit
Object 7 "Input - HVAC - disable" is identical to object 3 "Input - light - disable".

4.3. BRIGHTNESS THRESHOLD SWITCH

This block has two output objects: Threshold switch and brightness value
4.3.1. OBJECT 8 THRESHOLD SWITCH BRIGHTNESS - SWITCHING
Output 1 bit
Output object 8 sends an "ON" if the measured brightness is greater than the Value for switching the threshold value switch parameter. If the measured brightness drops below the Switch-on threshold value – (minus) the
Hysteresis parameter, an "OFF" is transmitted.
4.3.2. OBJECT 9 BRIGHTNESS VALUE
Output 2 bytes
Output object 9 sends the current measured brightness value in lux. The transmission is triggered by changes that are greater than the parameter Transmission of the light value in case of a change of or cyclically with the
time stipulated for Cyclical transmission of the light value.
If the cycle time is set to "OFF" there will be no cyclical transmission.

4.4. AD calibration value

Output 2 bytes
Object 10 is not transmitted autonomously. It can only be read. Its unsigned 16 bit value represents the momentary value of the AD converter for the brightness measurement.
The brightness measurement can be calibrated as follows:
• Measure the incident light - on a desktop for example - with an external lux meter. This represents
the reference lux value.
• Read out the AD calibration value (communication object 10) in the ETS.
Note: In the menu Read/send value, use type 7.001 unsigned 2 byte counter!
The AD value read then appears in the Value received menu as 739 pulses, for example.
• With full access, enter the two values Lux value and AD calibration value as parameters.
