short-circuit signal to devices requiring short-circuit
signal. The short-circuit signal is controlled by the
timer power supply.
6 Timer power output socket
This socket offers an AC220V voltage to other
device, which is controlled manually or by time
schedule.
7 Timer power supply fuse
In case of fuse blowing, please replace the fuse with a
new one with the same specifications. If this failure
still exists, please check the circuit for failure.
