The innovative My Switch Supervisor MSS-21 device is autonomous (no additional components are required for its wiring) and is specifically designed for complete and intelligent control of the water heater. With a single command, either from the built-in button (START) or remotely via a wired button, the water heater is activated and operates without any time setting until the water reaches the proper temperature. Once the water is heated, the My Switch Supervisor MSS-21 permanently disconnects the water heater from the power supply.
The device does not reconnect the water heater when the water cools down — activation occurs only with a new command.
It offers energy savings, enhanced safety, and helps maintain water hygiene.
