iZone C325D2 Daikin Air-Conditioner Interface Module
The iZone C325D2 is a communication interface designed to connect an iZone C225 control system with compatible Daikin ducted and VRV air-conditioning systems. It enables integrated control of the air conditioner through the iZone touchscreen, zone sensors and app when a Smart Hub is installed.

Connection Requirements
Connects to the Daikin indoor unit’s P1/P2 terminals
P1/P2 polarity is not critical for the standard interface connection
Requires shielded, two-core twisted-pair cable
Communication cable is not supplied by iZone
Connects directly to the iZone C225 CPU module
Important Compatibility Information
Some older Daikin systems, particularly selected R410A models, require the earlier C325D module and will not operate with the C325D2. For systems of 20 kW or larger, the Daikin controller must be used to commission and test-run the system before connecting iZone.
Always confirm the complete indoor and outdoor model numbers before ordering.
