8. Operation
Reset to factory setting
To return to factory settings:
• Press and hold the setup key
, the display now counts backwards
from “10” to “00” in second intervals.
• The appliance is reset at value “00”
Note:
To cancel the reset process, release the setup key
before the count-
down reaches “00”.
Energy saving
Set the required hot water temperature on the appliance.
If the water is too hot reduce the temperature on the appliance instead of
mixing with cold water.
Adding cold water wastes valuable energy that has been used producing
excessively hot water.
Also, any cold water added is not controlled by the electronic circuitry
meaning that precise temperature control can no longer be guaranteed
when supplying more than one outlet.
Power limit
If the maximum power available from the appliance is insuffi cient to heat
the volume of hot water being drawn off to the required temperature, the
control valve automatically reduces the fl ow rate so that the set tempera-
ture is reached.
Operating with solar systems
When operating with solar systems, the appliance should be used with
a thermostatic mixing vavle or a tempering valve to ensure that the inlet
temperature does not exceed 70 °C.
If the inlet temperature exceeds 70 °C, the display screen will show
