Technical Description
W3
The W3-application can be used either for offi ces or for hotel rooms. It is
well-suited for systems with variable airfl ow (VAV) with both supply air and
extract air. Four outputs are used to control heating, cooling, supply and
extract air. The damper motors are adjusted depending on the generated
airfl ow and duct pressure in both the supply and extract air ducts.
Three inputs are used; for condensation sensors, window switches and
presence detectors. The principle is to use minimal, normal or high airfl ow,
depending on occupancy and sensor status.
