9.2.3.2.1
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.
The curve is adjusted according to the outside temperature, 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.

Static Pressure Main Screen
1. Go to Climate > Static Pressure.
2. Define:
o
Band: The static pressure level below or above which the controller must close or open
the inlets to minimize or maximize the ventilation. Range: 0 – 20 Pascal.
o
Pressure Targets: Set the required pressure level for the cold and warm outside
temperatures.
o
Outside Temperatures: Set the temperatures at which the inlets open or close. (This
parameter requires an outside temperature sensor).
o
Pressure Alarm: Set the low and high pressures, at which an alarm is transmitted.
