TMEC3E Wi‑Fi: the new benchmark for residential electric water heaters

The TMEC3E Wi‑Fi is Thermowatt’s third‑generation smart mechatronic thermostat for residential electric water heaters. It combines precise electronic temperature control, high‑reliability mechanical safety with manual reset, and dual‑band Wi‑Fi 6 (2.4/5 GHz) connectivity to deliver a modern, dependable experience, from installation to daily operation via the MyThermowatt App.

With its self‑learning ECO mode and weekly Scheduling, TMEC3E Wi‑Fi optimizes heating cycles to ensure hot water when needed while reducing energy waste, supporting the achievement of ErP energy class “B” depending on the heater configuration. The Boost function quickly provides extra hot water during peaks, while OTA updates keep the device continuously up to date.

A compact design with front‑facing screws and optimized cable entries helps installers and retrofits by cutting time and complexity. Safety is guaranteed by electronic controls and a mechanical high‑limit cut‑out; Antifreeze and Antibacterial protections are enabled by default and can be disabled by the user if needed.

The device is ready for Consumer‑Led Flexibility / Demand‑Side Response (CLF/DSR) programs, allowing automatic cycle adaptation when users enter agreements with authorized aggregators to support the grid balancing.
