44 Chapter 5 Functional description Manual Corrigo Ventilation, revision R
When used with 2-speed fans they will start using reduced speed when the CO
2
value rises above
control value one and switch to normal speed when the CO
2
value reaches control value two. The
fans will stop when the CO
2
value falls 160 ppm below control value one.
If demand controlled ventilation is activated in combination with mixing dampers, and the CO
2
-
value rises above the setpoint value, the dampers will let in more outdoor air. The function is
controlled by a PI-controller. See section 5.1.3 Heat exchanger types.
The function has a settable minimum running time.
