What you can connect

Each light output (L) takes up to 6A resistive. Connect one light per output, never in series or parallel. Keep LED or CFL to 40W, or the contacts may weld and stay on. Use 240V mains LED strips only, never 12V or 24V.

The 4 Switch also has one high-load output (H) for up to 16A resistive, such as an AC up to 2000W (about 2 ton). Connect heavy appliances to H only. The 2 Switch has no high-load output.

The module has built-in over-current protection. A BLDC fan with its own remote can go on any output; the module switches it on and off, and the fan remote sets the speed.
