Damper setting
The dampers included in the zoning box have a built-in control
system that allows you to manually set the maximum and minimum
opening of each damper according to the needs of each installation.
Average Flow (REG)
Due to the unique characteristics of each Daikin indoor unit supply
opening with respect to the dampers of the box, the flow
distribution is not identical in each damper. The central dampers
receive more airflow than the others and the damper in the first and
last position receives the least amount of air flow.
This zoning box offers maximum aperture adjustment which
balances the flow of each damper to the needs of the installation.
By default, the dampers are configured with a maximum opening at
Position I
. To adjust the control of the dampers proceed as follows:
•
The damper must be completely closed to mechanically
adjust its flow. To make this adjustment, create demand in all
zones so that the indoor unit runs at maximum capacity.
Then deactivate the zone to be adjusted, and verify that
there is no air supplied to that zone.
•
With the damper closed, place the lever marked REG in the
actuator to the desired open position. There are 4 position (I,
II, III, and IV) with position I being completely open and
position IV having the slightest opening. Perform the setting
of the dampers by changing the lever REG position,
