Water Heater Switch

The water-heater switch controls the boiler power circuit and is designed to switch the corresponding load safely. It retains local control while adding remote commands through the system.

The heater can run on a schedule, start before expected hot-water demand, or switch off during a long absence. Automation must account for heating time and must not interfere with the appliance’s built-in safety functions.

Permissible current, number of phases, wiring arrangement, contactor requirement, fitting format, and communication protocol are determined by heater power and the electrical installation. Wiring must be completed by a qualified electrician with protective earthing and appropriate circuit protection.
