A CO sensor is used to control the air handling unit inde-

The unit can be set to run with a reduced basic air volume
(min.) for basic ventilation.
If the CO level in the room exceeds the programmed lower
2
limit (A), the CO sensor will increase the air flow. If CO
2
continue to rise, the air flow will be increased linearly up
to the maximum volume (max.) at the upper CO
and above.
Between the CO level upper and lower limits, the air flow
2
is increased and reduced fully automatically between basic
and maximum air flow.
If the CO level falls to the programmed lower limit (A) or
2
below, the unit will run with the standard air flow again.
To use this function, the timer flow or the default flow has
to be reduced. See "Timers" on page 17 or "Default flow"
on page 19.

If the unit is completely controlled by the CO
start with a little more than the standard air flow (min. +x)
when the CO level exceeds the programmed lower limit

plus 10 % (A + +10%).
If CO levels continue to rise, the air flow will be increased
2
linearly up to the maximum air flow (max.) at the upper CO
limit (B) and above.
Between the CO level upper and lower limits, the air flow is
2
increased and reduced fully automatically between standard
and maximum air flow.
If the CO level falls below the programmed lower limit (A),

the unit will stop again.
To use this function, the CO
as a start parameter using the "Startup guide", Airlinq User
Tool or Airlinq Service Tool.
Factory settings:
Lower limit A: 500 ppm (Min CO
Upper limit B: 900 ppm (Max CO
min: 30% (Min air flow)
max: 100% (Max air flow).

Settings can be made using the control panel menu points
"Default air flow" (see page 19) and "Startup guide" (see
page 20), Airlinq User Tool or Airlinq Service Tool.
