Fitting controller
the controller is provided with a wall-mounted back
cover. Prior to fitting the controller, it is advisable to
check whether the controller is able to control the rele-
vant sunscreening products from the proposed position
and whether it receives any signals from the outdoor
sensors.
Note: it might take some minutes until the controller
receives signals and shows the sensor values.
Even if the mains supply has been disconnected, the
controller saves the registered products and sensors.
However, date and time are only saved for 30 seconds
after disconnection of mains supply.
