If the settings are changed, please note these on this sheet for future reference. These will be needed if a PCB
replacement is required and a manual data transfer is needed.

Parameter setting notes
• 2: Values in Menu 2 cannot be adjusted.
• 4: Menu 4 OFF water ow rate
The temperature of the outgoing hot water is monitored by a built-in sensor. If the temperature of the outgoing hot
water rises more than 3 °C (default, or 6 °C if 4b) above the selected temperature shown on the digital monitor or the
preset limit when water controllers are tted, the burner will automatically go out.
• 6: Menu 6 Remote controller safe program
Factory default is ON. If a controller has been continuously connected for more than six hours, the PCB
automatically defaults to controller only mode, making the assumption that the water heater will always be connected
to and operated by a controller. This means if a controller is disconnected, the inbuilt safe program will only allow the
unit to deliver a maximum temperature of 42 °C. If this safe program is not needed, change menu 6 from A (ON) to b
(OFF).
• 7: OHS for solar applications
N/A for New Zealand models, this is for Australian models only that have di󰀨erent temperature settings. Please
remember that the A-Series and the EF26 are not suitable and will not be warranted for solar applications.
• 8: Prevention of condensation on the manifold (EF26 only)
If exhaust gases go back into the combustion chamber, condensation on the manifold nozzle causes error 11. To
prevent this, the post-fan time (fan revolution after combustion) can be controlled as follows.
