5. DZK Interface Board
This Interface provides the communication between the DZK zoning
box control board and Daikin Indoor unit, connecting to “P1 P2”.
6. Actuator control outputs
These outputs are used to drive the damper actuators with 12VDC
control for each damper.
7. Alarm input (normally closed)
When this input is open it will stop the Daikin indoor unit and close
all dampers. This input is shipped with a jumper in the connector
that should be left in place unless an alarm input is connected.
8. Protection probe input
This input is used to connect the supply temperature sensor.
9. Heating stages
If the system includes Auxiliary Heat, when required by the heat
demand, these outputs enable the first and second stages of
Auxiliary Heat.
The technical specifications for the 1
st

Stage Aux. Heat relay
are: I
max.
=1 A @ 24V, dry contacts.
If higher power is required for control, use external contactors of
appropriate capabilities.
10. Power supply
Power supply 110/230 VAC line. The Zoning box control board is
protected by a self-resettable fuse. This is an electronic component
that does not require any action other than cycling the power to
perform the reset.
