Load control panel
Description
The load control panel is a device that enables displaying the status of the loads
controlled by the load control central unit, item F521, and force their operation inde-
pendently from the central unit itself. It is therefore possible to:
- Force the priority of the load: in this case the central unit cannot disable the load for 4
hours.
- Re-enable a load disabled by the central unit: the duration of this operation lasts for 4
hours, unless the button is pressed manually.
The device consists of 2 modules, so that it can be installed in supports of the Livinglight
and Axolute series. It has 4 buttons on the front for forcing the load and 4 red LEDs that
indicate the status of the load:
- OFF with load ON
- ON steady, load disconnected due to overload.
- ON flashing (1s ON, 1s OFF), load forcing.
- ON, flashing at 1 s in programming phase and flashing at 125 ms in self-learning
phase.
The load control panel is equipped, at the front, under the cover, with a programming
button and, at the back, it has a bay for 7 configurators: P1-ab, P2-a, P2-b, P1-cd, P2-c,
P2-d, M.
Technical data
Operating power supply with SCS BUS: 18 – 27 Vdc
Max. current draw: 7 mA ; Operating temperature: 0 – 40°C
Configuration
If the device is installed in a My Home system it can be configured in two ways:
- PHYSICAL CONFIGURATION, inserting the configurators in position.
- Configuration via MYHOME_Suite software package, downloadable from
www.homesystems-legrandgroup.com; this mode has the advantage of offering many
more options than the physical configuration.
For a list of the procedures and their meanings, please refer to the instructions in
this sheet and to the "Function Descriptions" help section in the
MYHOME_Suite software package.
Self-learning configuration
To assign each of the buttons on the load control panel to the actuator of the load to be
controlled, the procedure is as follows:
1) Press the programming/self-learning button; all the LEDs will start blinking (1s ON,
1s OFF).

2) Press the button (a, b, c, d on the panel) that you want to assign to the load, the LED
assigned to it will begin to flash with a frequency of 125 ms, while the other LEDs of the
device will switch off.
3) Press the button of the actuator that you want to assign to the load control panel.
4) Repeat steps 2 and 3 for all the buttons (including any button that you have already
assigned in case you want to change it).
5) Briefly press the programming/self-learning button to exit programming.
WARNING: The socket of configurator M must be configured on 1 and all the other sockets
P1-ab=P2-a=P2-b=P1-cd=P2-c=P2-d=0.
