Master and slave modules
The base modules are called slave modules and a base
module with control equipment is called a Master.
A Master can control a maximum of 7 slave modules.
The control equipment is supplied in factory-mounted
condition or can be ordered separately for upgrading a
slave module to Master.
The slave modules receive control voltage from the Master
for regulating air dampers and valve actuators.
Pressure measurements and calculations required for
regulating the airflow in the room take place in the
Master.
The Master presupposes that all the modules in the room
act in exactly the same way and have exactly the same
C-factor, commissioning pressure and accordingly also the
same airflow.
In order for the Parasol VAV system to operate in the best
way, the following is recommended:
• Constant pressurisation in the zone
• Symmetric arrangement of the modules (so that the
commissioning pressure will be as equal as possible in
every module)
• The modules in the room should all be the same size
• All the modules should have the same nozzle configu-
ration (C-factor)
Recommended arrangement
If the modules in the room have different commissioning
pressures, it is advisable to locate the Master where the
commissioning pressure is somewhere halfway between
the lowest and the highest commissioning pressure in the
room; see Example 1.
The Master registers and adjusts the airflow. When the
commissioning pressure differs substantially between the
modules, it is important to consider the location of the
Master in order to obtain an airflow in the room that is as
correct as possible.

Example 1
In this example, we want 175 l/s (630 m3/h) in the room when there is max. occupancy. The Master is located between
the lowest and highest commissioning pressure in the room.

5, Slave Parasol VAV 1200 HF H-H-H-H 60 Pa 32.4 116,6
Sum: 174.7 l/s 628,9 m3/h
The sum of the actual airflow will thus be 174.7 l/s (628,9 m3/h)which means that the difference between the required
airflow and the actual airflow will be minimal.
Example 2
Example 2 shows the same system and commissioning pressure in the modules in the room but now the Master is
installed at a different location, consequently the difference between the required airflow and the actual airflow is
greater, compared with Example 1.
In this example, we want 175 l/s (630 m3/h)in the room when there is max. occupancy. The Master is located by the
highest commissioning pressure in the room.
Module number Model Nozzle configuration Pressure The module's airflow

5, Slave Parasol VAV 1200 HF H-H-H-H 60 Pa 30.3 109,1
Sum: 163.4 l/s 588,2 m3/h
The sum of the actual airflow will thus be 163.4 l/s (588,2 m3/h) which means that the difference between the required
airflow and the actual airflow is about 7%.

To calculate the airflows

k= C-factor
pi= (q/k)2[Pa]
q = k × √pi [l/s]
Short sides (1+3)
Fetch the C-factor for the sides (1+3) from the table.
Measure commissioning pressure pifor the sides (1+3).
Then calculate the airflow for the sides (1+3) using the
formula:
k (1+3) × √(pi(1+3) => q (1+3)
Long sides (2+4)
Fetch the C-factor for the sides (2+4) from the table.
Measure commissioning pressure pifor the sides (2+4).
The calculate the airflow for the sides (2+4) using the
formula:
k (2+4) × √(pi(2+4) => q (2+4)
Total airflow
The total airflow of the module is the sum of the short
and long sides:
qtot = q (1+3) + q (2+4)
N.B! pi(1+3) ≠pi(2+4)
NOTE: The commissioning pressure is different for
the short sides (1+3) and the long sides (2+4).

Conductor W4.1 VAV,
Commissioning/Checking the airflows
This information is a summary of the most important
points in connection with commissioning, checking the
airflows and adjustments.
For more detailed information see also Conductor
Technical Manual and Parasol VAV Product Datasheet at
swegon.com.
• Use CONTROL Zone dampers or equivalent dampers for
the best operation and constant pressurisation in the
zone.
• Check that all the products/constituent units are ener-
gised.
• Check that Conductor W4.1 VAV is set to Parasol VAV.
- Appl. parameter
- P_1964
- Value = 3
• Check that the Modbus address is correct if Super WISE
or another BMS is used.
- The Modbus address is unique for each room.
• For a correct Modbus addressing in the SuperWISE, the
room numbering is done in steps of 4.
Example
The master product in room no 1 shall have Modbus ID 4
The master product in room no 2 shall have Modbus ID 8
The master product in room no 3 shall have Modbus ID 12
• Check the pressure sensor's address
- SA1 = 3
- SA2 = 6
-EA = 4 (optional: extra pressure sensor if the extract
air damper is controlled from Conductor)
To set the C-factors and airflows
The Conductor W4.1 VAV calculates how the air damper
should either open or close in order to obtain the required
airflow. The Conductor W4.1 VAV calculates the airflow
in the air duct on the basis of the C-factor (resistance) and
the pressure in each air duct.
The C-factor SA1 and SA2 respectively are the sum of
C-factor of SA1: long sides (side 2 + 4) and SA2: short
sides (side 1 + 3) for all the modules (Master and slave
modules) connected to a Conductor W4.1 VAV.
• Check and adjust, if required, the C-factors and airflows
• Ensure that the C-factors of the SA1 and SA2 and the
required airflows are correct:
- RE Settings
- C-factor SA1 = Enter the total C-factor for the long
sides.
- Norm SA1 = Enter room's required airflow for occu-
pancy.
- Boost SA1 = Enter the maximum airflow for the
room.
- C-factor SA2 = Enter the total C-factor for the short
sides.
- Boost, SA2, does not have to be changed since the
setting for SA1 is used even here.

Vacancy flow
Conductor W4.1 VAV can also manage extract airflows.
Enter the vacancy flow as a percentage of the occupancy
flow (Norm SA1).
• Check and adjust the vacancy flow in menu P_1938.
To check the performance of the actuators
• Check that the valve actuators for chilled water and
heated water are operating correctly.
- Settings - Commissioning – Water
- Activate and open the valve actuators with Cool
valve - Open or Heat valve – Open.
- Check after 2 - 3 minutes the actuator's indicator
which should now be in the raised position above
the enclosure which indicates that the actuator is in
the open position.
Commissioning and checking the airflows
Before you begin commissioning, ensure the following:
• The air handling unit has been started up
• The fire dampers, if required, are fully open
• The zone damper is in full operation
• Open the air damper of all the modules:
- Settings - Commissioning – Water
-Air – Max.Occ – On
The modules will now adjust themselves to product the
airflow that has been entered in Boost SA1.
• Check that the max. flow has been reached.
- Adjust the pressure setpoint of the zone dampers
upwards using the TUNE Control hand-held termi-
nal until the correct airflow has been obtained. If
the max. flow has still not been obtained, you can
close another/other zone damper(s).
The module (reference module) with the greatest devia-
tion from the design max. flow can be found by measur-
ing the max. flow of all the modules in the zone.

• Set the minimum flow on a number of modules or use
the zone damper for setting the minimum flow so that
the ventilation system responds to the simultaneous
load.
• Adjust the pressure setpoint of the air handling unit
so that the zone damper of the reference zone is 85
– 90% open. (Managed by the SuperWISE if one is
used).
• Reset all the settings and set the Conductor W4.1 VAV
back to the normal operation setting.
• Check the measured max. and min. flows using the
room unit or via the Super WISE if one is used.

• Restore the pressure setpoints on all the zone dampers.
