Enabling condition (optional)
A third enabling condition can be defined on request. In the menu
beside a value for the outside moisture content can be defined,
which, if passed under, disables the free cooling.
Only when this value plus the adjustable hysteresis is exceeded, free
cooling is again enabled.
To measure the outside moisture content you need a sensor with the
parameterised sensor purpose "outside moisture content".
