an excellent product for an unbeatable value for money. used to regulate a radiator inertia 1800 W whose infrared remote control is not working. placed in a simple white wall-mount housing, bought at DIY corner store. fit perfectly. silent, it does not hear when lighting and extinction. switching on and off by simply pressing the middle button. clear and self-illuminated LEDs. requires no power switch as handles up to 3600 W. well above a great brand model, noisy ignition and extinction, requiring the installation of a power contactor.
