Mixing dampers (Recirculation and/or Recirculation 2 dampers)
Control
The analogue output signal (”Recirculation 1” & “Recirculation 2”), control two
dampers in separate sequence (“Recirculation 1” & “Recirculation 2”) for gradual
mixing of outdoor air and recirculated air. In this mode the output signal decreases
with increasing heat demand.
CO2
If Recirculation and CO2 controlled ventilation is activated in combination with mixing
dampers, and the CO2-value rises above the setpoint value, the dampers will let in
more outdoor air. The function is controlled by a PID-controller. Factory settings: P-
band 100ppm and I-time 100 seconds. These values can bee changed under menu
PID-controllers.

It is possible to select whether the compensation (0...10000) should increase or
decrease the fan setpoint. The 0...10000 compensation follows the current control
quantity for the fans.
