Water volume notes:
The water volume function is designed to warn, by a beeping sound, that a certain
volume of water has been delivered from the water heater. It does not stop either the
flow of or the heating of water.
The Kitchen controller does not require priority nor to be on in order to set the water
volume function.
The water volume function can be set whilst a hot tap is open.
The water volume alarm will only sound from the kitchen controller.
The factory preset water volume is 180 litres.
To turn off the water volume function before the alarm sounds, press the water volume
button twice.
The water volume is measured as the water flows through the water heater. Therefore if
more than one hot tap is open, the alarm will respond to the total water volume drawn
from all taps and the expected water volume from the first tap will be decreased.
If the hot tap is closed before the set water volume flows through the water heater and
the water volume button is left on, then the alarm will sound when the remaining water
volume is consumed during a later operation. To prevent the alarm from sounding,
press the water volume button twice to turn it off.
