General Description

The macro "HUA_RelHumSteam" for steam humidifiers provides room- or return air relative humidity P- or PI-control with adjustable comfort zone for humidifying and de-humidifying. .

To prevent the risk of wet ducts, the module provides maximum limitation of the supply air relative humidity.

The macro includes plant mode overrides.

It generates a coded signal “HumidityMode”, which if connected to other modules, enables those modules to save energy. E.g. stop cooling during humidification.
