Page 3: Introduction
1 Introduction This manual describes the functions of the “KNX 2-channel shutter actuator” and the “KNX 4-channel shutter actuator” (GW90856 and GW90857 respectively), and how they are set and configured with the aid of the ETS configuration software. 2 Application The GW90856 shutter actuator is used to command two separate groups of motors, each with a maximum of two 230V ac motors. -

Page 5: Parameters
Parameters 3.1.1 Operating mode Determines the device operating mode, by means of the following values: Shutter This is the default setting. If selected, it determines specific parameters and communication objects. Venetian blind This option is an alternative to the one above. It adds further parameters and different communication objects. - Page 6 movement of the load, whereas a short operation of the key will stop or close the louvres of the load (if "venetian blind” is set). 3.1.4 Percentage position command object With this parameter it is possible to enable the communication object via which you can set the percentage position of the shutter/venetian blind, leaving the actuator to perform the necessary movement;...

this is used to set the percentage value after a downward movement via the parameter “Louvres percentage position after downward movement”. The percentage values range from 0 to 100 (0% is the default). 6 “Channel x automatic calibration” menu The Channel x automatic calibration menu contains the parameters shown in figure 6.1. Fig. - Page 13 after n movements it is possible to define after how many movements the device must perform an automatic calibration; each time the device reaches the limit switch, the movement counter is reset. The values that can be set range from 1 to 30 (the default value is 10). ...

Page 14: "Channel X Forced Positioning" Menu
7 “Channel x forced positioning” menu By activating the “Forced positioning function” in the General settings menu of the relative channel, the “Ch.x - Priority command” communication object will be visualised. In addition, the Channel x forced positioning menu will appear, with the parameters shown in figure 7.1. Remember that the forced positioning activation command has a higher priority than any other bus command, including the block function. - Page 15 If the operating mode is “venetian blind”, then the “Louvres percentage position when forced positioning is deactivated” parameter is also visualised. This is used to select the required value; the percentage values that can be set range from 0 to 100 in 5% steps and with a default value of 50%.

Page 16: "Channel X Block" Menu
8 “Channel x block” menu By activating the “Block function” in the General settings menu of the relative channel, you can block the device in a specific condition (settable) following the arrival of the “Ch.x - Block” communication object which activates the block function itself. Until this function is deactivated, no other command received on any communication object is executed (apart from the forced positioning activation command). - Page 17 when the block function is activated, a downward movement is commanded. percentage position this option visualises the “Percentage position with block activated” parameter, used to define the percentage position of the load. If the operating mode is "venetian blind", then the “Louvre percentage position with block activated”...

9 “Scenes channel x” menu By activating the “Scenes function” in the General settings menu of the relative channel, you can enable this function that allows you to repeat a specific pre-set or previously stored position whenever the “Ch.x - Scene”... - Page 19 The “Initial position scene 1..8” parameters are used to define the percentage position of the load linked to channel x, and which the actuator must repeat when it receives the communication object for the execution of the nth scene; the percentage values it can assume range from 0 to 100, in 5% steps. The respective default values are: ...

Page 20: 10 "Channel X Alarms" Menu
10 “Channel x alarms” menu By activating the “Alarms function” in the General settings menu of the relative channel, you can enable this function that allows you to avoid any weather-related damage to the load connected to the actuator. There is a specific “Channel x alarms” configuration menu for enabling special communication objects that interface with weather sensors (rain sensor, wind sensor, etc.). - Page 21 value “1” the relative wind alarm is activated with a value of 1 (the default value). For each wind alarm enabled, the following parameters are visualised: “Behaviour on wind alarm 1..3 activation” (for defining the behaviour of the device when the relative wind alarm is active), “Behaviour on wind alarm 1..3 deactivation"...
- Page 22 10.1.2 Rain alarm function Apart from the wind alarm, it is also possible to enable a communication object for monitoring rain. This is done via the “Rain alarm function” parameter, which is disabled by default. Enabling the rain alarm, the “Ch.x - Rain alarm” communication object is visualised along with the following parameters: “Rain alarm activation value”...

This is done via the “Ice alarm function” parameter, which is disabled by default. Enabling the ice alarm, the “Ch.x - Ice alarm”...
- Page 24 percentage position this option visualises the “Percentage position with ice alarm deactivated” parameter, for defining the percentage position of the load. If the operating mode is "venetian blind", then the “Louvre percentage position with ice alarm deactivated” parameter is also enabled and is used to define the percentage position of the venetian blind louvres.

Page 25: 11 "Channel X Automatic Mode" Menu
11 “Channel x automatic mode” menu If “Automatic mode” is activated in the General settings menu of the relative channel, the device can perform autonomous implementations to take advantage of sunlight for heating the environment (for example). It is possible to define the position to which the load must be moved if the user requests protection against the direct light of the sun's rays, requests making use of the sun to heat the environment or requests suitable positioning of the load to protect against the sunlight to keep the environment cool. -
Page 26: Parameters
The activation of the automatic mode enables the Channel x automatic mode menu, containing the parameters shown in figure 11.1. Fig. 11.1 11.1 Parameters 11.1.1 Delay on solar radiation protection activation [s] The activation of the solar protection function via “Ch.x - Automatic mode function selection” may be delayed, with a time lapse ranging from 0 to 3600 seconds (the default value is 0). - Page 27 Automatic mode enabling Automatic mode 1 = Sun protection function selection Evaluate sun presence for solar radiation protection For sun protection, it is possible to define the behaviour of the device in the presence of and without sun. Using the “Sun presence object=1” parameter, it is possible to define device behaviour when the set operation is "solar radiation protection"...
