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 insufficient 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 flow 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
70
º
C.
If the inlet temperature exceeds the set point,
the “SUN” symbol on the display indicates that
the heating power is switched off.
