The recommended process for Balancing the system is:
1.  On page “1/2 Balancing (PI)”, check the Minimum, Maximum Cooling, Maximum Heating and Reheat airflow setpoints are correctly config-

ured for the zone.

2.  Check airflow sensor is correctly calibrated at zero:
• On page “2/2 Balancing (PI)”, set Damper Override to Close.
• Wait for measured “Airflow level” to stabilize and confirm the value is less than the desired Minimum Airflow. If not, confirm damper is 

closed and the airflow sensor is auto-calibrated at zero. 

3.  Before setting the Minimum and Maximum Cooling airflow, make sure that when fully open, the airflow is at least 40-60 CFM higher than 

the planned Maximum Cooling airflow. Otherwise, the control will be erratic. 

 

Minimum and Maximum Cooling Airflow

When damper is fully open, the airflow must be at least 40-60 CFM higher than the planned Maximum Cooling airflow. Failure to follow these instruc

-

tions can result in erratic airflow control depending on the system design.

4.  Calibrate sensor at Minimum airflow:
• On page “2/2 Balancing (PI)”, set the Damper Override to Minimum Flow. The displayed Airflow Setpoint will use the value of Minimum 

Airflow.

• Wait for the Room Controller measured “Airflow level” to stabilize.
• Take a reading of the actual airflow using a calibrated balometer.
• Enter the actual airflow as the “Balometer” value on “2/2 Balancing (PI)”. The Controller will calculate and display a new Minimum Flow 

Offset.

• Wait for the measured “Airflow level” to stabilize again. The Airflow level should now match the Airflow setpoint. Repeat if necessary. 

5.  Calibrate sensor at Maximum Cooling airflow:
• On page “2/2 Balancing (PI)”, set the Damper Override to Maximum Cooling. The displayed Airflow Setpoint will use the value of Maximum 

Cooling Airflow.

• Wait for the Room Controller measured “Airflow level” to stabilize.
• Take reading of actual airflow using a calibrated balometer.
• Enter the actual airflow as the “Balometer” value on “2/2 Balancing (PI)”.
• The Room Controller will calculate and display a new Maximum Flow Offset.
• Wait for the measured “Airflow level” to stabilize again. Airflow level should now match the Airflow setpoint. Repeat if necessary. 

6.  On page “2/2 Balancing”, revert the Damper Override to None allowing the system to return to normal operation.
