CONTROL PANEL
The control panel is composed of : display, function selection keys, general
switch and the hydrometer it is placed in the lower left corner
in front of the unit (see image above).
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.
