Service menu 1: Ventilation mode
1. Select the function "Ventilation mode" in the service menu, confirm by pressing "OK"
2. Select the ventilation mode: Monozone / CAV or Multizone / VAV
3. Confirm by pressing the "RETURN" key and return to the service menu
Service menu
Ventilation mode: Monozone / CAV
= Operate the ventilation unit in the constant airflow mode
Manual:
If it is necessary to operate the ventilation unit with a defined flow rate, then the manual operating mode
"Monozone / CAV" is recommended. The desired flow rate is set on the main menu by pressing the flowra-
te value.
1. "Monozone" = activated unit mode
2. Confirm by pressing the "RETURN" key and return to the service menu
Ventilation mode Monozone
Automatic:
In case of connected and activated sensors in "Service menu 10", the ventilation unit can also be opened
in Automatic mode. Press the "M" key. The unit changes to Automatic mode which is indicated with an "A".
Depending on the connected and activated sensors, it is also possible to enter a "limit value (ppm)" for the
respective sensors. When the limit value is reached, the ventilation unit will operate at the max. power avai-
lable. The ventilation unit therefore increases or decreases the flow rate capacity before reaching the limit
value depending on the target/limit value comparison.
Pressing the „A" symbol again switches the unit back to the "manual" ventilation mode („M" symbol).
Ventilation mode Monozone
Ventilation mode: Multizone / VAV
= Operate the ventilation unit in the constant pressure mode
Some ventilation applications require the use of the ventilation unit in constant pressure mode ("Multizone"
/"VAV"). The „constant pressure" operating mode is typically selected if the ventilation unit is to ventilate
different zones/units (Multizone) with variable flow rate requirements.
1. Enter "Multizone" / "VAV" mode by pressing the "Monozone" key.
2. The current "Flow rate value (m
set "Constant pressure (Pa)". The desired constant pressure value can be increased or decreased by pres-
sing the +/- key. The minimum constant pressure value is limited to 20 Pa.
Ventilation mode Multizone
Note: Constant pressure means static pressure in the duct network. In case of changes in pressure
in the duct network (e.g. by opening and closing shutters), the set constant pressure (target value)
is achieved by regulating the airflow rate (reduction or increase of the ventilator speed).
