What is the correct way to use a square dual load wireless adaptive phase dimmer (C4-SDAPD240-N) for Non-dimmable loads ?

I have been trying to use a square dual load wireless adaptive phase dimmer (C4-SDAPD240-N) to toggle a non dimmable lighting load.
After few toggles, the switch starts indicating an error (blinking red).

On Composer, it notifies in red that it's a short circuit.

the proper solution for a non-dimable load would be to use a switch. Depending on the type of load that you have connected to the dimmer it could be pulling too much current and actually damaging the dimmer. If it is going into a short circuit like this it is not going to work and will kill the dimmer.

and actually damaging the dimmer

or the load (likely a motor) for that matter will get damaged.

 

While dimmers can be made to 'act' more or less like a switch in that you can set the minimum on to 100% and the ramp rates to the shortest interval (always forget it that's 100ms or 250ms) that doesn't make it an actual switch.

Those settings may work fine for certain non-dimmable lights (ie non dimmable LED bulbs - if it'll work is NOT a given though) - it's not meant to be running motors such as pumps or bathroom fans etc.

Also if the issue is that you're getting a short: it certainly wouldn't work to 'just' make it 'act' like a switch.

Yeah, don't do that.
