9.2 Characteristics and interpretation of the wiring diagram references.
The control panel is self-protected and protects the electropump against overloads, short circuits and
overtemperatures, with manual reset. It comes complete with terminals for connecting the motor P1 and the control
floats.
Complete with terminals to allow the use of an alarm float and with terminals (without potential) for remote feeding of
an acoustic or luminous alarm. Provided with a button for manual or automatic operation of the electropump.
The internal transformer is supplied complete with a self-resetting protection against overloads or
short circuits, which manually cuts out the supply voltage for 3 minutes.

Selector for MANUAL - 0 - AUTOMATIC operation of each electropump where:
�� MANUAL
= electropump P1 is manually controlled by the operator as long as the impulse
is maintained
�� AUTOMATIC = electropump P1 is controlled directly by the floats or thermostats and zone
valves .
Automatic magnetothermal switch, for protection of the P1 motor supply line against overloads and short
circuits, with manual reset.
Set on QM1 the current indicated on the motor data plate.
Supply line insulating switch with door locking handle which may be padlocked.
Connection terminals for the water minimum/maximum level control float.
Contact characteristics: 24V a.c. 37mA
Connection terminals for the minimum level (A - Stop level) maximum level (B - start level) control floats.
Contact characteristics: 24V a.c. 37mA
