10. Additional features
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 this will be indicated by
“MAX” on the display.
Reducing the fl ow rate will enable the required temperature to be delivered.
Operation with solar systems
The appliance is suitable for use with solar heating systems providing appropriate
controls are in place to ensure that the temperature of the water entering the unit
does not exceed 70ºC.
If the inlet temperature exceeds the set point, the “SUN” symbol on the display indi-
cates that the heating power is switched off.
