7.2.3.2 Static Pressure Control
When set to pressure control, the static pressure (the difference between the interior and
exterior air pressures) controls the inlets opening and closing (the opening position is
determined in the Inlet & Curtain Levels screen). Maintaining the proper pressure enables
air to enter the rooms at the right speed and direction and ensures efficient air exchange.
Note that the Trio adjusts the inlets' opening only if one or more fan is operating.
Set the required pressure, according to the air flow specification. The greater the
difference between the exterior and interior pressures, the greater the air flow.

7.2.3.2.1 Static Pressure in Minimum Ventilation or Extra Ventilation
In minimum/extra ventilation the target pressure is adjusted as a function of the outside
temperature. Trio calculates the pressure target according to a curve between low and high
temperature target pressure set points.
NOTE Static pressure ventilation does not operate in tunnel mode.
The curve is adjusted according to the outside temperature, in order to maintain the
pressure. If the outside temperature is warm, large amounts of slow moving air is allowed
to enter the house (low static pressure). When the outside air is cold, the Vent Master
adjusts the inlets to allow a low volume of fast-moving cold air (high static pressure).
NOTE Version 4.1.6 supports opening the vents at 0% ventilation.
