Using It on the Job

1. Safety First: Always isolate power to the Bonaire unit at the main switchboard before starting any work on the controller.
2. Access Old Controller: Carefully unclip or unscrew the existing wall controller from its mounting plate.
3. Disconnect Wiring: Take a photo or make a clear diagram of the existing wiring connections, then safely disconnect the old unit's wires.
4. Install New Controller: Connect the new CT5431029SP controller following your wiring notes, ensuring all terminals are secure and correctly matched.
5. Mount and Test: Secure the new controller to the wall, restore power to the system, and thoroughly test all heating, cooling, and fan functions to ensure proper operation.

Limitations & Safety Notes

• This controller is specifically designed for compatible Bonaire cooling and heating systems only; it will not work with other brands.
• Always ensure the main power supply to the HVAC system is isolated and locked out before attempting any installation or service work.
• Installation should only be performed by a qualified technician or a competent individual with knowledge of electrical wiring, following manufacturer guidelines and Australian electrical standards.
• Check your existing controller's part number or your Bonaire system's manual to confirm compatibility before purchase.

Before you yank off the old controller, snap a quick photo of the wiring. Even if you've done a hundred of these, it's a cheap insurance policy to get the wires back in the right spot first go.
