Core opening in mm Pa Pa Pa Core opening in mm Summer operationWinteroperation Installation The ZTV valves can be easily installed in existing supply openings. They are fixed to ducting by pressing fitting in(with rubber gasket) or via three concealed fixing holes in frame with supplied screws. Function The thermostat operates automatically within a temperature range of –6°C to +20°C. Within this range airflow volumes between 0 and 30 m Advantages Features – Operation
Outside temp. in °C Innovative thermostatic supply air valve for automatic, temperature controlled replacement air. Efficiently combines energy savings and permanent ventilation. Permanent control of intake air flow volume with adjustable coreopening for all rooms. Suitablefor natural (thermic) ventilation and for intake air element combined with mechanical extract.
Core opening in mm Automatic core opening depending to outsidetemperature. – – – Totally closed without spacer ring. Number of units
3 /h are achieved conformingto DIN guidelines (see diagrams on the right). In its standard setting the valve closes completely for air temperatureslower than –4 °C. A minimum air intake is ensured by the built-in 4 mm wide distance clip. The initial setting of the valve can be changed manually by rotatingthe centre core. One full rotation equals a gap of 4 mm (see blue marked areas in diagram). Fully automatic to demand aircontrol. The number of required intake elements is to be defined according to DIN 1946, Pt. 6 in dependance to the apartmentsize and wind force (see table above).
