iZone C325B Braemar Air-Conditioner Interface Module
The iZone C325B is an air-conditioning interface module designed to integrate compatible Braemar single-phase inverter ducted systems with an iZone climate-control and zoning system.
Connected to the iZone C225 CPU, the C325B enables centralised control of the Braemar air conditioner through a compatible iZone wall controller. When the system includes an iZone Smart Hub, users can also control the air conditioner locally or remotely through the iZone Home app.

Important Installation Information
The Braemar proprietary wall controller is required during initial setup.
The indoor unit must be configured to use the return-air sensor in all modes.
The iZone control setting must be enabled within the Braemar service settings.
Zone, master and RF sensors cannot be selected as the controlling sensor for the air-conditioning unit.
Connect the C325B to the indoor unit’s CN1 terminal using shielded two-core twisted-pair cable.
The supplied short connector cable must be extended to suit the installation.
X/Y communication polarity is critical.
The indoor fan static-pressure setting must be configured to suit the installed duct system.
