With a space-saving design and multiple mounting options—including wall and ceiling configurations—the LEC fits easily into both new-build and retrofit projects. Its compact footprint makes it ideal for commercial and industrial environments where floor space is at a premium.

Built-In Summer Ventilation Mode

The LEC isn’t just for heating—its fan-only mode allows for air circulation during warmer seasons. This improves overall air quality and comfort by preventing stale air and supporting better ventilation throughout the year.

Features

Fully Compatible with BMS & Renewables

Designed with integration in mind, the LEC supports 0–10V input and Modbus control protocols, making it fully compatible with Building Management Systems. It also aligns with renewable energy strategies by operating efficiently on clean grid electricity or on-site renewables like solar PV.
