The ventilation level is expressed as a percentage. The control computer uses this percentage to find the required
ventilation 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-table
Required 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 the
ventilation level increases further, so will the modulation percentage.
•
Air inlet control depends on the settings. The control computer can open the air inlets 30% (midway
between 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 the
positions from the combi-table. The combination of exhaust and inlet positions creates a certain under pressure in
the house. The required under pressure is in the combi-table. The control computer can influence position of the
air inlets and accurately control the pressure. (Optimisation).
The control computer can control the fans modulatingly. Modulating means that a control (linear or relay) is
activated only during a part of the total cycle time. Modulating control allows minimum ventilation to be achieved
using, 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 modulation
These types are explained in the next sections. This explanation is also relevant for linear controlled fans.
