D. Installation - Flap
D.1.2.6 Conditionings
Path: Home> Installation> Climate> Flap> Conditionings
Normal heating functioning can be influenced by some block condition.
The intervention of those blocks is visualized in Zoom on Flap and in Climate blocks (par. F.1).
D.1.2.6.1 Increase pressure
Path: Home> Installation> Climate> Flap> Conditionings> Increase pressure
By this conditioning the flap working pressure can be conditioned to the outdoor temperature.
This function is very important, as it allows the flap opening to be decreased during winter conditions
so that cold air is pushed upward.
If the outdoor temperature drops below this setting the Air pressure
set will be increased (as set at D.1.2.1).
The amount the Air pressure set is increased for every 1° the
outdoor temperature drops below the Outdoor temp. set value.
Maximum increase of the Air pressure set.

Above 10.0° of outdoor temperature (Outdoor temp. set) the flap working depression will be 20 Pa, at

For every 1° decrease of outdoor temperature when
the Block is activated (Outdoor temp. set),
the Pressure set of the Flaps is increased until a
maximum value set in Max. press. increase.
This function is very important, as it allows the flap
opening to be decreased during winter.
