9.3.13 Setting Start-Up Detection for a Dishwasher
The start-up detection can only be set for the load type Dishwasher. With other program-controlled
loads, the power consumption right after switch-on is normally too low for start-up detection.
With start-up detection, there is no need to manually set the SMA radio-controlled socket to the
operating mode Automatic. This is an advantage, for example, if the SMA radio-controlled socket is
difficult to access behind the dishwasher.
With start-up detection activated, the SMA radio-controlled socket detects when the dishwasher starts
a program and switches the dishwasher off again instantly. Then, the Sunny Home Manager can
schedule the dishwasher into the load control accordingly and at the appropriate time switch the
dishwasher back on automatically via the SMA radio-controlled socket.
Sunny Home Manager blocks start-up detection for the duration of the maximum program runtime in
order that the program can run without interruption even with fluctuations in the power consumption
of the load. You specify the maximum program runtime when configuring the load (see Section 9.3.8
"Entering the Maximum Program Runtime", page 69).
If you wish to start the load even though start-up detection is activated, you must set the operating
mode of the SMA radio-controlled socket to Manual switch-on (e.g. by activating the touch key on
the SMA radio-controlled socket, via the Sunny Portal mobile app or in Sunny Portal via the page
Load balance and control, tab Current). This way, the load can start immediately and, in the
SMA radio-controlled socket, the start-up detection is blocked again for the duration of the maximum
program runtime so that the load program can run without being interrupted by the start-up detection.
Requirement:
☐ The load must be a dishwasher.
☐ The SMA radio-controlled socket must have at least firmware version 12.12.111.R. You can
read off the firmware version via the parameter Software package (see Section 8.5,
page 55).
If you have integrated an SMA radio-controlled socket with a firmware version lower than
12.12.111.R into the PV system, the SMA radio-controlled socket will receive the newest
firmware version within 24 hours.
☐ The SMA radio-controlled socket must be in the operating mode Manual switch-on.
Procedure:
1. In the field Start-up detection, activate the checkbox Active.
2. If required, in the text field Power threshold for detection, adjust the preset threshold for the
power consumption of the load during start-up (refer to the load manual for information on
power consumption during start-up).
3. If required, in the text field Detection time, adjust the minimum preset time period for which the
threshold of the power consumption must be exceeded in order to detect a start-up of the load.
