Thermostats/Twin=Thermostats/Hygrostats.

> Thermostats are used as temperature controllers. They can switch filterfans or heaters
to adjust the temperature in cabinets.
> Twin thermostats are switching units in various temperature ranges, they use less space than 2 single devices.
> Hygrostats switch on heaters or filterfans when a preset relative humidity is exceeded. Combined hygrostats/thermostats ensure temperature inside the control cabinet is always correct and condensation build-up is prevented.
