• Check that the correct number and combination of controllers have been installed for the specific model
Infinity. Refer to controller compatibility table below.
• Check controller is turned ON.
• Check there is 12VDC power supply available to the controller from the Ezi-connect terminals.
• If there is 12VDC available from the Ezi Connect but no controller display, check wiring between Ezi-connect
and controller is sound.
• If there is no power from the Ezi-connect terminals, but the hot water functions correctly, replace PCB.
Error Code 12 as soon as hot water tap is turned ON.
• Check 12VDC internal wiring to Ezi-connect terminal is not crushed or shortened.
• Rectify wiring and re-close Ezi-connect cover carefully.
Controller not showing display - (Wireless Controllers)
• Ensure transceiver module is mounted in the correct location, as per wireless controller installation instructions.
• Ensure 2 x AA batteries are in good working order and installed with the correct polarity within the wireless
controller. (Battery polarity details on rear of wireless controller)
• Ensure distance between wireless controller and transceiver does not exceed 50 metres.
• Ensure channel has been allocated to each wireless controller.
• Ensure wireless controller has been programmed to the transceiver correctly, as per wireless controller
