Balancing of a damper-optimised DCV system consists of the following steps:
- Control that all the DCV units,room sensors/ room regulators etc. have supply voltage and no polarity error.
- Program the actual maximum and minimum airflow rates values (Vmax and Vmin) on each DCV damper and set the dampers to automatic mode.
- If the DCV units do not give the expected response, check the polarity on the supply voltage.
- Complete the VAV control form. The completed control form should be included in the documentation of the ventilation system.
