3.4.1 Load modes introduction
This controller has 5 load operating modes which will be described below:
Mode
Sole light control
(nighttime on and daytime off)
Light control + time control
1 to 14 hours
Manual mode
Debugging mode
Normal on mode
No.
Descriptions
When no sunlight is present, the solar panel voltage is lower than the light
control on voltage, and after a time delay, the controller will switch on the
load; when sunlight emerges, the solar panel voltage will become higher
than the light control off voltage, and after a time delay, the controller will
switch off the load.
When no sunlight is present, the solar panel voltage is lower than the light
control on voltage, and after a time delay, the controller will switch on the
load. The load will be switched off after working for a preset period of time.
In this mode, the user can switch the load on or off by the keys, no matter
whether it's day or night. This mode is designed for some specially
purposed loads, and also used in the debugging process.
Used for system debugging. With light signals, the load is shut off;
without light signals, the load is switched on. This mode enables fast
check of the correctness of system installation during installation
debugging.
The energized load keeps outputting, and this mode is suitable for
loads which need 24-hour power supply.
3.4.2 Load mode adjustment
Users can adjust the load mode as needed on their own, and the default mode is debugging mode (see "load
modes introduction"). The method for adjusting load modes is as follows:

3.4.3 Manual load on/ off page
Manual operation is effective only when the load mode is manual mode (15), and tap the Set key to switch
on/ off the load under any main interface.
