The Helios EHSD 16 is an advanced electronic temperature-controlled semiconductor regulator designed specifically for EHR fan systems. It features a robust aluminium casing suitable for mounting on walls or within control cabinets. This system allows for precise control of constant supply air or room temperature via optional external sensors such as the duct sensor TFK or the room sensor TRF.
The EHSD 16 also supports remote control functionality through an external setpoint generator TFR or by applying an external control voltage ranging from 0 to 10 V DC. Powered by a 400 V three-phase supply with a maximum current of 25 A, the unit is rated to IP20 standards, ensuring protection against solid objects but not water ingress.
