The Daikin Power and Communication Adaptor
(DPCA) provides an interface between the
Thermostat and Indoor Unit.
To install the DPCA:
1. Position the DPCA in a suitable location away
from water near the Indoor Unit (for example,
the backside cavity of a wall-mounted unit).
2. Connect the DCPA power cables to the
indoor Unit power supply terminals. Ensure
the electrical connections are securely
tightened.
3. Remove the DPCA cover by grasping both
sides and pulling along the length of the
DPCA.
4. Use the Wiring Harness to connect the P2
terminal on the DPCA to the S1 terminal on
the Indoor Unit’s main PCB. Refer to Daikin
system installation manual for information
about accessing the S21 terminal.
