I think I would also ask Legrand.com.sg if it is like that.

I have re-connected it in many ways. I think it's like that. Half lit & full lit. Doesn't off completely.

I switched over the 2 L&N and it's still the same. When it is off the LED light is a little lit. When it is on it's fully lit. Maybe the Legrand Water Heater switch is like that?

Did I reversed the main supply L&N with the appliance L&N in this 2 pole water heater switch ?!? If that is the reason why the LED light remains lit the whole time.

Just to mention the Legrand water heater switch's LED doesn't have like the MK's separate wires for the LED. The red LED light is built into the switch. I thought it's only turns on when you on the switch. But it just kept lit, though the water heater (water storage tank) power is working as it should be.

I have a problem with a new Legrand water heater switch that I changed out from my flat's original MK one. After I connected it up and got it working. The LED is always lit. In both OFF & ON position. I must have connected something wrongly. Any one can advise?
