The Helios HY 3 SI is a humidity controller designed for the regulation of individual or multiple ventilation units based on relative humidity. It provides continuous adjustment from 30% to 90% RH, with the setpoint configured via an internal rotary knob for tamper-resistant operation.
Housed in a durable white surface-mounted enclosure with an IP30 protection rating, the HY 3 SI includes a changeover contact suitable for both humidification and dehumidification. It offers a switching capacity of 3 A for inductive loads and 5 A for resistive loads. This unit is ideal for discreet humidity control in HVAC systems, ensuring reliable and efficient environmental management.
