The local command button (figure A) is used to perform the ON/OFF cyclical switching,
inverting the relay status each time they are pressed.
If the actuator can be commanded in timer mode by at least one KNX/EIB device then also
the local command button will send a timed command.
Local commands are not executed if a priority control is active.
WARNING: the local command buttons are enabled only when the BUS
power is available.
reinstatement of the bus power supply
If the power to the bus decreases below 18 V dc for over 1.5 ms the relay switches
to OFF (NA contact open, NC contact closed).
When the power is reinstated on the bus, the relay remains in OFF mode.
This device requires no maintenance. Use a dry cloth for possible cleaning.
