Keep in mind: make sure that
the zoning box is in its correct
position. (Actuators at the
bottom)
If upon receiving the unit it is determined that one of the outlets will not
be used, take the following actions:
1. Install the unit and wiring required to start with the Wired
Thermostat configuration. The unit should have all dampers open.
2. Configure the Wired Thermostat. Once the thermostat is assigned
to a zone, all other dampers will close except for the zone that is
assigned to the Main Wired Thermostat.
3. At this time, disconnect the motor cable from the outlet that will
not be used.
4. Permanently seal the outlet using the supplied plug and follow the
local installation recommendations.

The adaptor is shipped with the dampers fully open. One
of them includes a cover to be used in case one of the
dampers is not used. If the damper is not used, the contractor
needs to be sure that the cover will stay in place. If all
dampers are used, take the cover off and store it.
Insert a sharp pointed object through the frame holes and
the frame sealing to facilitate the location of the setting holes
used to assemble the zoning box to the indoor unit.
Remove the indoor unit collar. Insert a screw (not fully
tightened) in the bottom corners of the indoor unit as shown
in the following figure:
Sit the zoning box on the screws as shown below, and then
affix the box using the remaining screws.

Keep in mind: to maximize the air
flow for each damper, the best way
to disable dampers is to start
disabling from the ends to the
center, due to the position of the
DZK related to the air handler.
Keep in mind: when one or more
dampers are disabled, it is
recommended to adjust the
Airflow control parameter to avoid
overpressure on the active
dampers and ductwork
Attach each zone’s duct with its assigned damper. Follow
the local recommendations to insulate and seal the
ductwork with the damper. Make a cutout along the duct
to keep the motor outside of the insulation.
Use of the insulated stopper. If a damper is not used in the
installation, proceed as follows:
•Make sure the damper is closed before installing the
insulated stopper. (The damper will close as soon as the first
zone is assigned.)
•Check that the power cable is disconnected for the damper
motor that will not be used.
•Check that the damper remains airtight with the power ON
and the fan running.

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,

beginning with the central damper opening and ending with
damper No. 1 (Closest to the zoning box control board). The
reduced flow in the central dampers will increase the flow of the
dampers at the ends.
•The use of an anemometer verifies that the flow in each grille
is within the installation requirements.
Minimum Air (A-M)
Similarly, the zoning box allows a minimum air opening for each
damper, if needed. By default, the Position a damper is configured
in the full-close position. To adjust minimum air for any damper,
proceed as follows:
•Check that the dampers are wide open. To do so, set the
system to Stop user mode, from the Main Wired Thermostat.
•Perform the setting of the dampers by changing the lever
A-M position beginning with the central damper opening of
the box and ending with damper No. 1. (Closest to the
zoning box control board).
•With the damper open, place the handle A-M in the desired
open position. It has 4 positions (a, b, c and d) where position
“a" is fully closed and is "d" is the fully open.
•The use of an anemometer verifies that the flow in each grille
is within the installation requirements.
