Using analogical hydrometer.
The analogical hydrometer control panel has a dial with unit of measure in a
bar, from 0 to 6 bar. The water pressure in the heating system is indicated by
the index of the black arrow.
The optimum pressure for the system is between 1 and 1.5 bar.
More than 1.5 bar you can have a maximum pressure of 2 bar (maximum
expansion of the system during the rise in temperature). More than 2 bar
pressure the system is not in the range of operation, and mechanical safety
valve (preset to 3 bar) can start to lose water.
The minimum operating pressure is 0.8 bar (+/- 0.2 bar). The differential
positive or negative tolerance is due to the operation of the water pressure
switch with fixed setting.
