Hygrostat for Ventilation Control (483050)

Aumüller Hygrostat 35–100% RH for Ventilation Control (483050)

The Aumüller Hygrostat 483050 provides humidity-dependent control for electrically operated natural window ventilation systems.

It operates as an adjustable two-point controller, monitoring the relative humidity in the room and providing a switching signal when the selected threshold is reached.

Adjustable from 35 to 100% relative humidity

The required humidity threshold can be set directly on the front of the device within a range of 35 to 100% RH.

This allows the ventilation response to be adapted to the requirements of the room.

Typical applications include:

• sanitary areas
• changing rooms
• communal and utility rooms
• commercial buildings
• natural window ventilation systems
• rooms subject to temporarily high humidity levels

Connection to Aumüller ventilation controls

The hygrostat provides one changeover contact rated at 230 V AC / 5 A and is designed for connection to the ventilation switch input of compatible Aumüller SHEV and ventilation control units.

When used with EMB7X00 control units, the Aumüller Ventilation Interface Module 533601 may additionally be required to convert the continuous contact signal into a short pulse. According to Aumüller, this module is not required for the EMB8000+.

Compact surface-mounted design

The white plastic housing is designed for surface mounting indoors. Its compact dimensions of 74.5 × 74.5 × 25 mm allow discreet installation in the room being monitored.
