Day / night switch

The day-night contactor allows for supplying the water heater at the right time, automatically. The concept is simple: when electricity is cheaper, the device heats; the rest of the time, it stops. No need to think about it every day, the control is done automatically. The result: better controlled consumption, the same comfort, and a tank that operates smoothly.

The contactor is integrated into the electrical panel and generally offers an automatic mode and a manual mode for occasional needs. For installation and adjustment, it is better to rely on a qualified professional to keep the installation clean, secure, and compliant with best practices.

On ExpertByNet, the day-night contactor category features models designed for homes: compact format, clear terminal identification, accessible selection button, and thorough documentation.
