delay, the controller will switch on the load. The load will 
be switched off after working for a pre-set time. 

15 

Manual 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 specifically purposed loads, and also used in the 
debugging process. 

16 

Debugging mode 

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.  

17 

Normal on mode 

The energised load keeps outputting, and this mode is 
suitable for loads which need 24 hour power supply.  

 

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. 

Under any interface other than load modes, press and hold the Set key to enter into the parameter 
setting interface.  

 

After entering into the setting interface, tap the Set key to switch the menu for setting, and tap the 
Up or Down key to increase or decrease the parameter value in the menu. Then tap the Return key 
to exit (without saving parameter setting) or press and hold the Set key to save settings and exit.  

NOTE:

 After system voltage setting, power supply has to be switched off and then on again, 

otherwise the system may work under an abnormal system voltage.
