3. The LED1 display at bottom right hand side of water heater will display 1E.
4. Use the MIN button to change the left digit (0→1etc.) in the display to the
required maintenance code identified from the maintenance information
table on page 13.
5. Use the MAX button to change the right digit (E→F etc.) in the display to the required
maintenance code identified from the maintenance information table on page 13.
6. The maintenance code and the value of that code will alternate on the LED display.
7. If required, the maintenance information can be locked and will be unable to be modified
by turning dip switch 2 to the ON (up) position on the DIP1 set of dip switches whilst dip
switch 1 is also in the ON (up) position.
8. Switch all DIP1 dip switches to the OFF (down) position to return to normal operation.
With Remote Controller (a remote may only be used to assist during servicing):
1. Fit remote controller.
2. Restore power supply and ensure the remote controller is turned off.
3. Press the temperature increase and decrease buttons simultaneously for 3 seconds until
an audible beep is heard.
4. Use the temperature decrease button to change the left digit (0→1etc.) in the remote
controller display to the required maintenance code identified from the maintenance table
on page 13.
5. Use the temperature increase button to change the right digit (E→F etc.) in the remote

6. The maintenance code and the value of that code will alternate on the LED display of the
Remote Controller.
7. Press the on/off button twice on the remote controller to cancel maintenance information.
To turn the unit on while in Maintenance Mode, quickly press the ON/OFF button once. The
temperature will default to 50

C but will not display so maintenance information can be
displayed. If a hot tap is opened, the unit will operate and the “Y” maintenance information
can be viewed in real time (flow rate in litres per minute, flame rod status etc).
Clearing the Fault History
1) Turn the unit OFF. Remove the front cover. Locate the dip switches on the control board.
2) Make sure all the dip switches are in the OFF (down) position.
3) On the DIP1 set of switches, switch dip switch 1 ON (up) and OFF (down) again.
4) Within 5 seconds of turning the dip switch off, press and hold the MIN (SW1) or MAX
(SW2) button. The LED display will flash „CL‟. Once flashing ceases the fault history has
been cleared and the MIN or MAX button can be released.
5) Verify clearing of fault history by entering Maintenance Mode and check the code at
location 1E; it should read -- (no record).
