Connect to HVAC System: Wire the controller interface module to the Daikin outdoor unit and indoor fan coils.
Power Connection: Connect to dedicated 24VAC power supply.
Communication Wiring: Run shielded communication cables between controller, thermostats, and interface module.

WARNING! All electrical connections must comply with local codes. Disconnect power before installation.

First-Time Setup

Power on the system; follow on-screen initialization wizard.

System Initialization: Press and hold SETUP for 5 seconds to enter installation mode.
Zone Configuration: Assign each thermostat to a specific zone (1-8).
Set Date/Time: Configure current date and time for accurate scheduling.
Temperature Calibration: Calibrate each zone thermostat if needed.
Connect to Wi-Fi (Optional): Enter network credentials for remote access.
Test Operation: Run system test to verify all zones respond correctly.

CAUTION! Default system password is 0000. Change this during initial setup for security.
