Most solenoids work from 9 to 12 Vdc, but there are
some cases when solenoids must be powered with a hig-
her voltage. In these cases, we can do as follows:
Once this operation is carried out, the screen shows the
controller status.
Another characteristic of this controller is that it discon-
nects its screen in order to save energy. If we want to
program it again, we must press any key for a few se-
conds until it activates again.
To turn it off again, we will key in at the ‘’STATUS
SCREEN’’:
When validating, the screen will turn off, but the contro-
ller will be fully operational.
NOTE
The specific operation of this kind of controller
and the fact that the low power consumption of
all its functions is a priority, make inadvisable ins-
tallations that require an active input since this
means multiplying the power consumption and
therefore reducing its autonomy.
NOTE
Due to the fact that the highest power consump-
tion occurs when the screen is on, after learning
how to operate the controller during the first
programming, we recommend to swap the two
batteries so that the battery in best condition is
available for the electronics.

VERY IMPORTANT
Battery controllers switch the screen off to save
power consumption when no key has been touched
for a minute.
To switch on the screen again… Keep a key pres-
sed for a few seconds.
Electric connection to backwash valves
The connection to backwash valves is done through so-
lenoids. Current intensity must not exceed 1,6 Amp for
the total of solenoids connected simultaneously to the
output ports.
We must bear in mind that the internal transformer gives
a maximum intensity of 40VA, so we will take into con-
sideration the maximum power consumption, depending
on the number of solenoids and relays working simulta-
neously in the worst case scenario.
The Filtmaster filter cleaning controller can be connec-
ted either to continuous consumption solenoids or to
latch solenoids.
The connection is the same for 12 Vdc controllers, ta-
king into account the power supply polarity and the po-
larity of solenoids.
