cold water taken directly from the water mains line
.
Changing the water temperature (i.e. by acting on
the thermometer), will automatically also change the
dispensing time.
Setting a dispensing time of less than .5 seconds
will only allow for selection of cold water, or of water
at maximum temperature.

This time is compared with the subsequent dispen-
sing cycles to check whether there are any irregular
dispensing cycles.
