Pressure: Configuration of the values corresponding to the air side of the chosen expansion vessel.
- NOMINAL: Value of the nominal pressure or compressor stop pressure. Press on the box and enter the value of
the desired NOMINAL PRESSURE, between values from MIN 0.5 bar to MAX 5.0 bar. It is validated by
pressing ENTER button. By default the selected NOMINAL value is 1.5 bar.
Adjustment of pressurization values,
- HYSTER.: Pressure difference in BAR below which the compressor starts up until reaches the NOMINAL
pressure value or pressure difference above which the air solenoid valve is activated to expel air from the
expansion vessel until reaching the NOMINAL pressure. Click on the box and enter desired HYSTERESIS
value, between values from MIN 0.1 bar to MAX 1.0 bar. It is validated by pressing ENTER button. By default,
the selected HYSTER value is 0.0 bar.
- ALARM HIGH: Value of the pressure from which the LED on the MAIN screen is activated in red color, not
at all by high pressure. Optionally, RELAY1, RELAY2, RELAY3 can be used as a configuration of this type of
array to enable monitoring. The Screensaver in case of activation, will do in RED FLASHING. Click on the box
and enter the value of the desired ALARM HIGH value, between values 0.5 bar to 5.0 bar. It is validated by
pressing the ENTER button. By default the selected ALARM HIGH value is 5.9 bar.
- ALARM LOW: Value of the pressure from which the LED on the MAIN screen is activated in red color,
giving rise to an alarm due to low pressure. Optionally, RELAY1, RELAY2, RELAY3 can be used as a
configuration of this type of array to enable monitoring. The Screensaver in case of activation, will do in RED
FLASHING. Click on the box and enter the value of the desired ALARM LOW, between value from 0.5 bar to
5.0 bar. It is validated by pressing the ENTER button. By default the selected NOMINAL value is 1.0 bar.
Adjustment of pressurization values,

It must be ensured that the maximum operating pressure of the
expansion vessel indicated on the sticker attached to the tank is
never exceeded.
