Requires Braemar proprietary controller for setup |
Connect the Braemar proprietary wired controller to the FCU PCB
Enter the service mode parameters
To enter Service Mode, power must be connected to the unit and proprietary wired controller, and the unit must be switched 'OFF' at the wall control. Follow the steps below and refer to the function and parameter setting table
3. As per the instructions set the sensor to return air for all modes
4. Set the iZone control setting
5. Set the required static pressure setting
6. Cycle the power to the AC unit
7. Connect a 2 core, twisted pair control cable from the C225 / C325B X / Y to CN1 in the fan coil unit
