LEGRAND 4 121 72 Technical Data Sheet

Smart load shedder
1. DESCRIPTION - USE
Use:
. Allows the user to save money by decreasing his electrical
contract expenses while maintaining his comfort by avoiding power
supply shutdowns based on appliances priorities. Some of them
will never be powered off as considered as "high priority".
So, this module can measure the house total electricity
consumption via the included closed current transformer and to
display it on Home + Control smartphone app.
The load shedder is thus able to detect when the subscribed power
(or the maximum consumption threshold defined in the App) is
about to be exceeded and to intelligently turn off loads previously
connected to "with Netatmo" devices such as; Connected cable
outlets, Connected contactors, Connected power outlets... in
accordance with predefined priorities. These priorities can be
easily customized in the smartphone app.
Then, the smart load shedder will automatically turn back on these
loads after the drop of the consumption peak.
This connected version gets the following functions:
· Real-time measurement: automatically reads the total electrical
consumption of the home.
· History of electricity consumption, available in the Home +
Control app.
· Turn off/back on loads one by one for a very precise management
of the load shedding function.
· Set-up of the subscribed power / maximum consumption
threshold (which act as a load shedding threshold) and
customization of load shedding priorities between loads via the
Home + Control app.
Technology:
. Single-phase current measurement, by field effect using a
closed current transformer (delivered with the smart load
shedder) and data transmission by radio frequency to the
connected network.
2. RANGE

Requires beforehand installation of a "with
Netatmo" connected starter pack or a Control
module (gateway) and at least one product
from "with Netatmo" offer offering the
