BALANCING
Pressure Dependent
Pressure Dependent
Before starting to Balance the system, check if the following parameters are correctly configured in the Configuration menu:
• VAV Box Type
• Actuator Type
• Floating Actuator Time
Air Flow Balancing settings can be found on the Balancing page of the Setup menu.
The recommended process for Balancing the system is:
1. On page “Balancing (PD)”, set the approximate damper positions for Minimum, Maximum Cooling, Maximum Heating, Reheat, and
Damper Override.
2. For each position, repeat the following process:
• Set the Damper Override to the desired position (Minimum, Maximum Cooling, Maximum Heating or Maximum Reheat).
• Allow time for damper to reach defined position.
• Take reading of actual air flow using a calibrated Balometer.
• Compare actual airflow to desired airflow and adjust the Damper Position accordingly by adjusting the % value of the position options on
the Balancing (PD) page (see next page).
• Repeat until measured airflow at the damper position matches the desired airflow.
3. On page “Balancing (PD)”, revert the Damper Override to None to allow the system to return to normal operation.
