12 Load Control
SMA Solar Technology AG
Operating manual 83HM-20-BE-en-19
Requirements:
☐ The load must be connected to a switching device.
☐ For the load, a time period of the type Load CAN be switched on must be set.
Procedure:
• Set the slider to the required level.
12.4.8 Assigning a Switching Device
If a load is connected to the SunnyHome Managervia a switching device, you must assign the switching device to the
load:
• So that the SunnyHomeManager can measure the energy consumption of the load
• So that the SunnyHomeManager can read out the data of the load and control the load
• So that the SunnyHomeManager save the data of the load
If a load was temporarily not assigned to any switching device, corresponding data gaps will appear in the diagrams
such as Current status and forecast.
A load can be connected to another (free) switching device at any time and controlled via this; the measured values or
consumption data basically remain with the load and can only be called up via the load itself.
Procedure:
• In the drop-down list Device assignment, assign a device to the load for measuring and/or switching. By
default, no switching device is assigned to the load.
If the desired switching device is already assigned to a different load, a "*" will be displayed in front of the name
of the switching device. In order to be able to reassign the switching device, you must first remove the assignment
of the switching device in the profile of the other load.
12.4.9 Setting Measuring and Switching of the Assigned Device
As soon as you have assigned a switching device to a load, you must specify whether this switching device is to only
switch the load on and off or whether the energy demand of the load is to be measured as well.
These two options are explained in the table below:
Setting Explanation
The assigned device is to
measure and switch (intelli-
gent power consumption)
The load draws electric current via the switching device.
Using the consumption values measured by the switching device, the
SunnyHomeManager "learns" how much power the load typically consumes.
SunnyHomeManager uses this information for load planning and load control.
The assigned device is only
to switch, not measure
(fixed power consumption)
The load is switched e.g. via a relay which is connected to the radio-controlled socket.
Using the connected relay, the radio-controlled socket switches the load only in accor-
dance with the configuration (time period) and the specifications of the
SunnyHomeManager.
The value that is entered in the field Power Consumption is the power consumption
factored in for planning the load.
Procedure:
• In the drop-down list Measuring and switching, select the required setting.
12.4.10 Setting Automatic Switch-Off
☐ The load must be non-program-controlled.
