-Hygrostats from the FLZ series switch on control cabinet heaters or filterfans when a preset relative humidity is exceeded.
- The relative humidity is kept above the dew point and the condensation of water on electrical components and the corrosion of unprotected sheet metal is prevented.
- The electronic combination device unites thermostat and hygrostat in one housing and, at the same time, monitors the relative humidity and the temperature independently of each other.
