21 Brightness Main Value
This datapoint concerns automatic operation of the motor, therefore it is only effective if the mode is enabled with the "Automatic
Mode" datapoint, or to check the conditions planned by the AutoAtReset and AutoAtTime parameters.
Its function differs based on the setting of the DeviceType parameter.
Roller Shutters:
It is only visible when the ShAutoMode is set to "Internal light".
It can be connected to a device that provides brightness in Lux, and the value is compared to the ShCloseBrightness and
ShOpenBrightness thresholds. If the value is higher than ShCloseBrightness, the shutter is brought to the position indicated by
the ShShadePosition parameter (provided the current position is higher, otherwise it won't mode). If the value is lower than
ShOpenBrightness, the shutter is opened at a fraction equalling 10% of the stroke.
If receipt of this datapoint has produced shutter movement, for a time equalling the ShPauseTime parameter, no other movements are
carried out, independent of the brightness values received.
Awnings:
It is only visible when AwAutoMode is set to "1 light sensor" or "3 light sensor".
It can be connected to a device that provides brightness in Lux; if AwAutoMode is set to "1 light sensor", the brightness of the
environment is considered equal to the value received on this datapoint, if it is set to "3 light sensor", the highest value is chosen from
this and the datapoint value "Brightness Value #2" and "Brightness Value #3".
The brightness value obtained as such is compared to the threshold set in the AwSunThreshold parameter.
If the value stays over the threshold for a time over AwSunOpenDelay (i.e no other telegrams are received, or the value received is still
over the threshold), the awning is opened.
If the value stays under the threshold for a time over AwSunCloseDelay, the awning is closed.
22 Brightness Value #2
This datapoint is only available if the DeviceType parameter is set to "Awnings" and is only visible when AwAutoMode is set to "3 light
sensor".
It can be connected to a device which provides brightness in Lux; if the value received is higher than that received on the "Brightness
Main Value" and "Brightness Value #3" datapoints, the brightness of the environment is considered equal to this value.
The use of the brightness value of the environment is described in the "Brightness Main Value" datapoint.
23 Brightness Value #3
This datapoint is only available if the DeviceType parameter is set to "Awnings" and is only visible when AwAutoMode is set to "3 light
sensor".
It can be connected to a device which provides brightness in Lux; if the value received is higher than that received on the "Brightness
Main Value" and "Brightness Value #2" datapoints, the brightness of the environment is considered equal to this value.
The use of the brightness value of the environment is described in the "Brightness Main Value" datapoint.
24 Indoor Temperature
This datapoint concerns automatic operation of the motor, therefore it is only effective if the mode is enabled with the "Automatic
Mode" datapoint, or to check the conditions planned by the AutoAtReset and AutoAtTime parameters. It is only available if the
DeviceType parameter is set to "Roller Shutters" and is only visible when ShAutoMode is set to "Temperature".
It can be connected to a device which provides the indoor temperature in degrees Celsius (°C) and the value is compared to the
ShCloseTemperature and ShOpenTemperature thresholds. If the value is higher than ShCloseTemperature, the shutter is brought to the
position indicated by the ShShadePosition parameter (provided the current position is higher, otherwise it won't mode).
If the value is under the ShOpenTemperature the shutter is completely opened.
25 Current Time
This datapoint can be connected to a device that cyclically transmits a telegram containing the current time.
The information can be used to manage automatic operation on an hourly basis or close the shutter at night.
26 Automatic Up/Down
This datapoint concerns automatic operation of the motor, therefore it is only effective if the mode is enabled with the "Automatic
Mode" datapoint, or to check the conditions planned by the AutoAtReset and AutoAtTime parameters.
It is only visible if the ShAutoMode parameter (for shutters) or AwAutoMode (for awnings) is set at "External telegram".
When a telegram is received on this datapoint with the value 0 (up), the shutter/awning is brought to the upper limit position. When a
telegram is received with value 1 (down), the shutter/awning is brought to the lower limit position.
