Controlling My Water Heater to Operate Only During Off-Peak Hours

  • Hello,

    I would like to control my water heater so that it only turns on during off-peak hours. For this, I am planning to use:

    • a Shelly Pro 1,
    • a 2A 3kA C-curve circuit breaker, phase/neutral Hager,
    • a 20 A Hager fuse,
    • and a Legrand CX³ power contactor (reference 412523), 230V coil, no manual control, 2 poles, 25A, 2F contact, 1 module.

    I would appreciate your help with:

    1. The wiring of the Shelly Pro 1 with the contactor, circuit breaker, and fuse,
    2. The programming of the Shelly Pro 1 so that it activates the water heater only during off-peak hours.

    Thank you very much in advance for your help!


    Merci j'ai trouvé la solution.
