KNX system
devices, actuators,
sensors
Depending on the parameterisation, the actuator can be used as a
switching actuator or a blind actuator. Mixed configurations of
switching and blind actuators are also possible. For the blind
actuator function, two neighbouring relay outputs are combined to
form one blind output.
Features
- Blind or switching operation can be parametrised. In blind
operation, the adjacent outputs (A1/A2, A3/A4...) are combined
into one blind output. Mixed operation at one actuator (e.g. A1 &
A2 blind, A3 & A4 blind, A5 switching, A6 switching ...) is
possible.
- Actively transmitting feedback or status messages can be
delayed globally after a bus voltage recovery or ETS
programming operation.
- Manual operation of the outputs independent of KNX with
intelligent LED status displays for saving energy.
- Bistable relay.
- Supply from KNX bus, no additional power supply required.
- Simplified terminal connection (no terminal overlapping).
Blind functions
- Operating mode can be parametrised: Control of slat blinds, roller
shutters, awnings, skylights or ventilation flaps.
- Separately parameterisable movement times with movement time
extension for movements into the upper end position.
- For slat blinds, a slat movement time can be parametrised
independently.
- Switchover time for change of direction and times for short and
long-term operation (Step, Move) can be set.
- Feedback on the curtain or slat position. In addition, feedback on
an invalid curtain position or a drive movement is possible.
- Assignments of up to 5 different safety functions (3 wind alarms,
1 rain alarm, 1 frost alarm), or with cyclical monitoring. The
safety functions (objects, cycle times, priority) are created in a
device-based manner for all outputs. An assignment of individual
outputs to the safety functions and the safety reactions can be
parametrised based on the channel.
- Blocking function can be implemented for each blind output.
- Simple sun protection: Sun protection function with fixed and
variable curtain or slat positions at the beginning or end of the
function can be activated separately for each output.
- Up to 16 internal scenes can be parametrised per output.
- Scene memory function: Additional visual feedback.
Switching functions
- Independent switching of the switching outputs.
- NO contact or NC contact operation.
- Feedback on switching: Active or passive feedback function.
- Logical individual linking function for each output.
- Blocking function can be parametrised for each channel.
- Time functions (switch-on and switch-off delay, staircase light
function – also with advance warning function).
- Can be integrated in the light scenes: Up to 16 internal scenes
can be parametrised per output.
- Scene memory function: Additional visual feedback.
