User and Technical Manual 5.5 Adjustment The menu Adjustment Climate Natural temperature sensors setup Natural outlet setup At Natural ventilation, the opening of the air inlets is adjusted based on the input from the inside temperature sensors - and possibly a weather station. The livestock house can be divided into areas. Each area can be connected to one or several temperature sensors. - Page 17 User and Technical Manual Example 4: Setup of front display with Natural ventilation It can be advantageous to set up the front display so that it reflects the installation in the house. Air inlet The temperature sensors have a central placement on the display to indicate their placement in the house.

Page 21: Control Parameters
User and Technical Manual Example 6: The limitation of the opening of the air inlets based on wind direction On the windward side of the house the opening of the air inlets is limited based on wind direction. The more often the wind is directly on the house and the stronger it is, the small will the opening of the air inlet be. -
Page 22: Adjust Opening Of The Air Inlets And Air Outlet
User and Technical Manual The menu Control Parameters Reaction time of the air inlets. Integration time 15 mm:ss Longer time: slow reaction. Shorter time: quicker reaction. Example 7: Reduction of minimum ventilation at low outside temperature The reduction increases linearly (from 0 % at 5 °C, 20 % at -2.5 °C to 40 % at -10 °C). At an outside temperature of -2.5 °C, a minimum ventilation of 30 % is thus reduced by 20 %, giving a reduction of 6 %. - Page 23 User and Technical Manual Natural Ventilation...
