Low pressure switch (2).
The low pressure switch is connected to the inlet pipe in the gas train control unit. If the gas pressure is
too low, the power supply to the control unit is interrupted. The dehumidifier is then switched off
automatically, and a low gas pressure alarm is shown on the display of the burner control. The low
pressure switch has a range of 2,5 to 50 mbar. The standard setting is 5 mbar.
High pressure switch (1).
The high pressure switch is connected to the inlet pipe in the gas train control unit. If the gas pressure is
too high, the power supply to the control unit is interrupted. The dehumidifier is then switched off
automatically, and a high gas pressure alarm is shown on the display of the burner control. The high
pressure switch has a range of 30 to 150 mbar. The standard setting is 30 mbar.
Gas control valve module (V3).
This modulating regeneration air gas heating system includes a control valve installed in the gas line, on
the gas train line, and the gas burner. This makes it possible to vary the gas fl ow and burner capacity
during operation. The control valve is connected to an electric actuator that is controlled by the program
module by means of a 3-point signal, proportionally.
