Measuring Fan
Measuring fans measure the air speed inside the rooms. More exactly, the fan is used to precisely
determine the actual conveyed exhaust air volume. This device can be used for:
•
Measuring real time air speed
•
Enable ventilation compensation if the air speed does not meet the calculated minimum ventilation
requirements.
Define a sensor as Measuring Fan. Refer to Mapping Devices, page 48.

M
EASURING REAL TIME AIR SPEED
In this setup, the measuring fan is used to show the real time air speed.
1. Go to System > Devices & Sensor. On the Measuring Fan port:
a. Define the Related Fan as None.
b. Verify that the measuring fan is enabled.
2. Go to System > Control Strategy > Ventilation
.
3. In the Measuring Fan Usage parameter, define the usage as Monitor.
NOTE
The Measuring Fan Maximum Compensation parameter is irrelevant in this setup.

V
ENTILATION
C
OMPENSATION
In this option, the measuring fan is used to ensure that the air volume meets the minimum defined in the
Minimum and Maximum Ventilation, page 100. The Minimum Ventilation function defines the minimum
amount of air that the fans must supply. The Measuring Fan measures the actual amount of air supplied. If
the actual amount is less than the required amount of air, the Measuring Fan increases the speed of a
designated fan to compensate for the difference.
Define a sensor as Measuring Fan. Refer to Mapping Devices, page 48.
