Requires Gree proprietary controller for setup

  1. Connect the Gree proprietary wired controller to the FCU PCB

  2. 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

  1. As per the instructions set the sensor to return air for all modes

  2. Set the iZone control setting

  3. Set the required static pressure setting

  4. Cycle the power to the AC unit

  5. Connect a 2 core, twisted pair control cable from the C225 / C325G X / Y to CN1 in the fan coil unit

  • Indoor fan coil unit PCB: Note connector CN1

  • Connector and short cable provided: Insert the connector and short cable (see image below) into the connector CN1. Note the correct polarity for X & Y. Polarity is critical

  • C225 AC unit connector: Connect AC unit cable from fan coil to C225 as indicated

  • Polarity is critical: Make sure it is wired in accordance with these instructions on both the CN1 connector on the fan coil PCB and the C225 cable connector

    • Cable from CN1: Connect

    • Take  the R1 / R2 control wire from the fan coil unit  and connect it to the AC Unit Control Cable on the  C225 / C325P2
