11.7.1 Resetting the SunnyHomeManager
A SunnyHomeManager must only be reset if it had been installed in another system previously.
Loss of data due to replacement or due to resetting to default settings
If the SunnyHomeManager is reset to the default settings, all data saved in the SunnyHomeManager will be
deleted. The data saved in SunnyPortal can be transmitted to the SunnyHomeManager after calling up the PV
system again in SunnyPortal. Devices that were paired to the SunnyHomeManager via EEBus have to be paired
again.
Reset to default setting
1. Hold down the reset button with a pointed object until the LEDs flash red. This can take from 2 to a maximum of 6
seconds.
Pressing down and holding the reset button for less than 2 seconds has no effect.
If the reset button is held down for longer than 6 seconds, the SunnyHomeManager is restarted (see
Section11.8, page68).
☑ The LEDs flash first green and then red.
2. As soon as the LEDs flash red, release the reset button.
☑ All data stored in the SunnyHomeManager is deleted and the SunnyHomeManager restarts.
11.7.2 Reassigning the SunnyHomeManager to the SunnyPortal System after
the Reset
If you have performed a complete reset of the SunnyHomeManager, you must reassign the SunnyHomeManager to
your SunnyHomeManager system in SunnyPortal. Otherwise, SunnyPortal will not accept any data from the
SunnyHomeManager.
