Behaviour After Power Recovery; Maintenance And Cleaning - HomeMatic HM-LC-Sw1-Pl-DN-R5 Mode D'emploi

Behaviour after power recovery

During normal operation, the duty cycle is not usually reached. However,
repeated and wireless-intensive teach-in processes mean that it may
be reached in isolated instances during start-up or initial installation of a
system. If the duty cycle is exceeded, this is indicated by one long and
one short red flash of the device LED, and may manifest itself in the de-
vice temporarily working incorrectly. The device starts working correctly
again after a short period (max. 1 hour).
9 Behaviour after power recovery
After the device has been inserted to a socket or after power recovery
the switch actuator performs a self-test/restart (approx. 2 seconds). The
device LED flashes red, green and orange briefly (LED test display).
The device LED will flash if an error is detected during this check (see
sec. „8.1 Flash codes" auf Seite 36). This is repeated continuously and
the device does not perform its function.
If the test is completed without errors, the switch actuator transmits a
wireless telegram containing its status information. To prevent all Home-
Matic actuators from transmitting at the same time when power is re-
covered (after a mains power failure or a disconnection, for example),
there is a random delay before the switch actuator transmits. During this
time, the device LED slowly flashes orange. If the delay is very short, this
flashing may be almost imperceptible.

Maintenance and cleaning

The product does not require any maintenance. Enlist the help of an
expert to carry out any repairs. Clean the product using a soft, lint-free
cloth that is clean and dry. You may dampen the cloth a little with luke-
warm water in order to remove more stubborn marks. Do not use any
detergents containing solvents, as they could corrode the plastic hous-
ing and label.
