Regulating modes.

By means of the control board, the panels EEG-T3^S, EE2G-T3^S, EE3G-T3^S may be set to operate for two
different types of system:
- Water pressure booster set systems.

Regulation with constant relative pressure with internal PSET.
The pressure or head is set by means of the control board,
and remains constant, irrespective of the water request.

Regulation with constant relative pressure, with external PSET.
- Heating systems (circulators) with constant differential pressure.

Regulation with constant differential pressure with internal PSET.
This is set by means of the control board.
The head remains constant, irrespective of the water request.
Operation of only one circulator at a time, exchange of the starting order every 24 hours, automatic exchange to
the stopped circulator in the event of blockage of the operating circulator.
Operation of only one circulator at a time (default setting parameter 128).

Regulation with constant differential pressure with external PSET.

10. REFERENCES OF BUTTONS, SIGNALS AND COMPONENTS OF THE PANEL

The panels EEG-T3^S – EE2G-T3^S - EE3G-T3^S must be configured by means of the control board located on
the front of the panel, observing the signals on the display and setting the data with the keys described below.
