Boundary conditions for commissioning

Please ensure that the following conditions are met:
− Central ventilation unit set to constant volume and calculated total air volume.
For this purpose, follow the information in the operating instructions from the manufacturer of your ventila-
tion system . The ventilation level of the ventilation unit must not be changed during commissioning .
− Pipe network ready:
Ensure that the ventilation pipe network in the building is fully installed, all inspection openings are closed and the
duct network meets the hygiene and cleanliness requirements.
A contaminated duct network can lead to ventilation component malfunctions!
− The MZB is connected to the mains power supply. The MZB requires an external power supply.
− All valves are mounted and completely open.
− Ventilation calculations prepared for the connected utilisation unit and building.
− All ventilation components are freely accessible.
− Laptop with free USB A port and USB cable (A to B) and installed MultiZone software package.
A laptop/tablet with USB A output or corresponding adapter is required for the commissioning.
A USB A to B cable is also required (recommended length min. 2m, depends on installation situation).

Adjustment (measurement+adjustment)

1. Check in advance that all boundary conditions for commissioning are met.
2. Set the volume flows in the different levels (see 2.2. Ventilation).
3. Select the desired ventilation level for adjustment (see 2.2 Ventilation).
4. Wait until the system has stabilised before beginning the measurement.
Helios recommends waiting at least 15 minutes . The adjustment should take place at nominal volume flow .
5. Measure and add up the volume flows of all supply and extract air valves in the selected operating level.
6. Calculate the difference from the measured volume flows to the entered setpoints (setpoint-actual = difference).
7. Enter the values (positive or negative) for supply and extract air below the measured level under "Adjust".
8. Wait until the system has stabilised and repeat the measurement. (in case of further deviation, add the deviation
value to the set value, allow to stabilise and repeat measurement, if necessary).
9. Then set the respective calculated air volumes at the valves.

Errors

On the one hand, the error status of the MZB is displayed via the control elements with error indication on the display
(BET) or via flash codes LED (BE). The individual error codes can be found in the operating instructions for your cont-
rol panel.
On the other hand, the error status can also be retrieved using the configuration software under current valu-
es.
