KNHG Control Panel Hygrostat — Relative Humidity Control
Mechanical hygrostat for control of relative humidity within the control cabinet. Versatile functionality depending on requirement:
- To prevent build up of moisture = dehumidification mode (terminals 1 & 2)
- To increase moisture level = humidification mode (terminals 1 & 3)
Up to 10A resistive load can be wired directly through the hygrostat

Frequently Asked Questions
What's the difference between dehumidification and humidification mode?
Wire to terminals 1 & 2 for dehumidification (switches on as humidity rises), or 1 & 3 for humidification (switches on as humidity falls) — same unit, different terminal pair.
What load can I switch directly?
Up to 10A resistive.
What's the adjustable range?
10-90% relative humidity.
How is it wired?
2.5mm² cable, mounts to 35mm DIN rail.
Industry Applications
- Control panel climate control — prevents condensation-related corrosion and component failure
- Outdoor/humid-environment enclosures — maintains safe humidity levels
- OEM machine builders — simple mechanical humidity control without a PLC
