Reset to factory setting
To reset to factory settings press
the up arrow and down arrow
function keys simultaneously.
The display will count backwards
from ‘10’ to ‘00’ in one second
intervals.
The appliance is reset when the counter reaches ‘00’.
Releasing the function keys earlier will cancel the process.
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.
Note! Adding cold water wastes the energy used to heat it up.
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 DEX heater is insufficient to heat the
volume of hot water being drawn off to the required temperature, this will be
indicated by the LCD decimal point on the display.
Reducing the flow rate will enable the required temperature to be delivered
indicated by the decimal point remaining solid.
Operation with solar systems
Type DEX
(
excluding DEX12*
) are 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°C.
If the inlet temperature exceeds the set point,
the flashing decimal point on the display indicates that the heating power is
switched off.
*Note! DEX12 has a maximum inlet temperature of 25°C.
