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
A connector and short cable has been provided with the C325B but will need to be extended

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 a shielded, 2 core, twisted pair cable to the connector and short cable provided
