Switching functions
Channel use
In case of a switching module (master or switch extension), for each group of 2 channels, it is possible to use them individually for switching functions or use them together to control a shutter or a blind.
| CHANNEL USE |
|---|
| Not used |
| Switch / Staircase / Flash / Valve |
| Shutter / Blind |
Switch/staircase operation
- Independent switching of the switching outputs.
- Switching feedback mode active (transmitting after changes) or passive (object readout) feedback function.
- Blocking function can be set by a group object for each channel to prevent operating the channel from the bus.
- Timing functions (switch-on delay, switch-off delay, minimum on time and off time).
- A resettable hour counter can be enabled for switches to monitor the operating time of a channel and to trigger a warning after a certain time (ex. for maintenance purpose).
- Staircase function with an optional pre-warning function. Option to extend the staircase duration and to allow manual switch off during the staircase delay.
- Pulses can also be configured using the staircase function (minimum 1 second pulse).
- Valve control using ON/OFF commands, limit values, PWM or temperature control. A valve protection function can be enabled to activate the valve on a regular basis when no heating/cooling is required for long periods. Valve type (normally open/closed) can be configured.
- Up to 4 internal scenes configurable per output.
For each pair of switching channels, the main function can be selected :
| FUNCTION |
|---|
| Switch |
| Staircase |
| Flashing |
| Valve control |
The channel can be blocked from the KNX bus using the “Block” communication object. When a channel is blocked, the output stays in the last state it was before being blocked.
Shutter/blind operation
- Operating mode configurable: control of blinds with slats or shutters.
- Configuration of single speed or multiple speed motors
- Separately configurable blind travelling times for moves into the upper end and bottom end position.
- For blinds with slats, a slat moving time can be independently configured.
- Travel direction change-over time and the times for short and long-time operation (Step, Move) presettable.
- Relative positioning using steps and full moves or absolute positioning using position setpoint as percentage.
- Blind/shutter or slat absolute position feedbacks.
- Blocking function can be set by a group object for each channel to prevent operating the channel from the bus.
- Dimming function to allow motor operation while a button is pressed (start/stop) using a 4-bits dimming object.
- Configurable reaction on repeated or reversed commands.
- Additional time at full up/down positions for position correction.
- Configuration of up to 3 safety alarms
- Up to 4 internal scenes configurable per output.
Switch on/off
Parameters
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Scene control: Scene 1 Scene 2 Scene 3 Scene 4 | 0 (default) 1 to 64 | When set to 0 the channel will ignore corresponding scene. When set to another value, the channel will respond to this scene number. Channel state can be store using the scene group object for further recall. |
| Minimum ON duration Minimum OFF duration | No delay 100ms to 5 min. | Minimum duration the channel must remain in ON or OFF state before the next switching is allowed. In case of switching before the delay is elapsed, the switching action is delayed by the remaining time. |
| Switch ON delay Switch OFF delay | No delay 250ms to 60 min. | The ON or OFF delay causes a delayed switch of the channel. At sending a new switch signal to the channel, first the adjusted delay time expires and afterwards the channel will be switched. |
| Working hour counters | Disabled (default) Enabled | When enabled, a counter records the number of operating hours of the channel. The counter can be reset and a warning can be defined using the parameter below. |
| Working hours warning | 0 (default) 1 to 65535 | Number of hours of operation to trigger a warning. |

Staircase/pulse
Parameters
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Staircase duration | 1s to 12h | Total duration of the staircase lighting. The channel is automatically switched OFF after this delay. |
| Extend staircase duration | Disabled Enabled (default) | When enabled, the staircase duration is extended each time a ON telegram is received on the staircase object. |
| Manual switching OFF | Disabled (default) Enabled | When enabled, the channel is switched OFF when receiving a OFF telegram on the staircase object. |
| Prewarning time | No warning (default) 5s to 5 min. | A prewarning can be set before the end of the staircase delay. The channel is switched OFF for 1s and switched ON again until the end of the staircase duration. Prewarning time is the time before the end of the staircase duration. |
| Scene control: Scene 1 Scene 2 Scene 3 Scene 4 | 0 (default) 1 to 64 | When set to 0 the channel will ignore corresponding scene. When set to another value, the channel will respond to this scene number. Channel state can be store using the scene group object for further recall. |
| Minimum ON duration Minimum OFF duration | No delay 100ms to 5 min. | Minimum duration the channel must remain in ON or OFF state before the next switching is allowed. In case of switching before the delay is elapsed, the switching action is delayed by the remaining time. |
| Switch ON delay | No delay 250ms to 60 min. | The ON delay causes a delayed switch of the channel. At sending a new switch ON signal to the channel, first the adjusted delay time expires and afterwards the channel will be switched ON. |

Flash
The flashing function is activated by sending a “Start” command to the Flash object. The channel continues flashing at the frequency defined by the parameter until a “stop” command is received on the Flash object or until a switch command is received.
The flashing function should only be used for limited period otherwise the contact life of the channel will be greatly reduced.
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Flash duration | No delay 700ms to 5min | Flash ON period Flash OFF period is identical. |
Other parameters of the standard switch remain applicable.
