The possible flow rate and totalized volume units are the following:
Flow rate:
There are 9 combinations made from 3 volume units and 3 time units.
Totalized volume:
There are 3 possible volume units, l (litres), m3 (cubic meters), ga (gallons)
Note: 1ga = 3.785 litres.
With the working units chosen, by pressing the two push buttons PROG, we go to the loop
current programming.
