THERMOSTAT ADJUSTMENT
The water heater is supplied with the thermostat preset at 70ºC. It will be
necessary to adjust the thermostat temperature setting if another temperature
is required.
When adjusting the thermostat
temperature it is necessary to alter the
thermostat offset. The table outlines the
thermostat temperature and the
corresponding offset. Failure to adjust
the offset will result in incorrect water
temperature.
To adjust the thermostat setting and offset:
1. Press the down button (▼) for five (5) seconds. The current set point value
will be displayed.
2. Press the down button (▼) to decrease the set point or the up button (▲) to
increase the set point.
3. Once the required temperature is selected press and hold the down
button (▼) and the up button (▲) simultaneously. The display will revert to
the current temperature in the water heater.
4. Press and hold the down button (▼) and the up button (▲) simultaneously
for ten (10) seconds, “C0” (offset program) will be displayed. Release the
buttons.
5. Press and hold the down button (▼) and the up button (▲) simultaneously
again. The current setting for “C0” will be displayed. Release the buttons.
6. Press the down button (▼) to decrease the setting or the up button (▲) to
increase the setting according to the table, i.e. if the temperature set in step
three is 60 then the offset value will be 14.
7. Once the required offset is selected press and hold the down button (▼)
and the up button (▲) simultaneously, “C0” will be displayed.
8. Press the down button (▼) once; “EP” (exit program) will be displayed.
9. Press and hold the down button (▼) and the up button (▲) simultaneously;
the current temperature in the water heater will now be displayed and
programming complete.
Note: During the programming process if a button is not pressed for 25
seconds the thermostat will revert to its previous temperature display. It will be
necessary to start again from step 1.
