The control computer uses this percentage to find the requiredventilation settings in the combi-table. The control computer determines the ventilation % between two positions,and controls the modulating fans using this.Example: Taking ventilation positions from the combi-tableRequired ventilation level: 30%. This value is precisely between positions M3 and M4.The control computer uses the following fans:• Both fans are controlled on for 75% of the set cycle time (midway between M3 and M4). If theventilation level increases further, so will the modulation percentage.• Air inlet control depends on the settings. The control computer can open the air inlets 30% (midwaybetween positions M3 and M4). The inlet position can also be modulated between 21% and 39%.The control computer controls ventilation with fans (exhaust) and air inlets. The control computer takes thepositions from the combi-table. The combination of exhaust and inlet positions creates a certain under pressure inthe house. The required under pressure is in the combi-table. The control computer can influence position of theair inlets and accurately control the pressure. (Optimisation).The control computer can control the fans modulatingly. Modulating means that a control (linear or relay) isactivated only during a part of the total cycle time. Modulating control allows minimum ventilation to be achievedusing, for example, a large fan.Fancom differentiates between the following types of modulating control:• Modulating control with fixed modulation times• Modulating control with optimised modulation times• Modulating control with MicroControl®• Rotating modulationThese types are explained in the next sections. This explanation is also relevant for linear controlled fans.
