The Helios EHS is an advanced electronic temperature controller designed for regulating EHR electric heating elements in ventilation systems. Housed in a durable white plastic casing for convenient wall mounting, the EHS provides precise temperature control via semiconductor regulation technology.
Equipped with a built-in temperature sensor, it supports constant supply air or room temperature control. The system can be switched to operate with external duct or room sensors (available as accessories) for enhanced flexibility. The EHS automatically detects the supply voltage, adapting to 230 V single-phase or 400 V two-phase (L‑L) power supplies, with a maximum current of 16 A. Rated to protection class IP 20, it ensures reliable performance in indoor environments.
