MAESTRO is connected
to a classic electrical
installation.
All of the outlets are
dry contacts which
are normally open
(NO) and can interrupt
up to 230 V-10 A
(above this, add a
contactor).
The 3-position interrupters
are kept.
The filtration interrupter
makes it possible to rinse
the filter using the FORCED
OPERATION/STOP positions.
If used with MAESTRO, use
position CLOCK.
The lighting interrupter
remains in STOP position.

MAESTRO needs to obtain information on filtration; a parallel connection is
made on the filtration contactor coil at the A1 and A2 terminals. 230 V is
present when the filtration runs.
