Response To Power Recovery - HomeMatic HM-LC-BI1PBU-FM Installation And Operating Manual

11 Response to power recovery

When the operating voltage is switched on (recovery
of mains voltage), the actuator checks its components.
The LED will flash if an error is detected during this
check. This is repeated continuously and the device
does not perform its function.
If the test is completed without errors, the actuator
transmits a wireless telegram containing its status
information.
To prevent all actuators from transmitting at the same
time when power is recovered (after a mains power
failure or a disconnection, for example), there is a ran-
dom delay before the actuator transmits. During this
time, the device LED flashes (as in teach-in mode).
If the delay is very short, this flashing may be almost
imperceptible.
