14) ALARMS ON THE DISPLAY
• ERROR 1
The valve can't find the correct position.
When this signals appears, check whether the camshaft rota-
tes or if it is stationary.
1. If the cam shaft rotates:
- Check whether the magnetic sensor is in the correct posi-
tion or if it is broken (fig. 9, G);
- Check whether the cable or the connector connecting the
timer to the magnetic sensor are connected correctly or if
they are damaged (fig. 9 H, I);
- Make sure the cam shaft is assembled correctly and is not
inclined;
- Check whether the magnets are all inserted in the cam
shaft (fig. 9, E);
2. If the cam shaft does not rotate:
- Check if the cable connecting the motor and the timer is
disconnected or assembled incorrectly (fig.9, A,D,B).
- Make sure the motor is not out of order or hindered in its
movements.
• ERROR 2
This signal indicates that the timer couldn't read all the data
in the program.
To refresh the data, disconnect the power connector from the
timer (fig. 10, A) and re-connect it.
If the error message is resolved, set again the timer by en-
tering the needed parameters (see chapter 5, "SETTING THE
SOFTENER").
If the error persists, disconnect the power connector from
the timer (fig. 10, A) and reset the day and time following the
instructions in paragraph 4.2.

• REPLACE BATTERY
This alarm indicates that the battery must be replaced.
To remove the battery (fig. 9, L), disconnect the power supply
to the softener, remove the back part of the cover, then pull
up the front part of the valve.
Replace the battery (CR1220 3V), put back in place the front
and the back cover. Reconnect the power supply.
Once the battery is replaced, set again time and date (see
paragraph 4.2).
15) PROBLEMS AND SOLUTIONS
Some solutions to fix the problems that might arise are propo-
sed in the following tables.
The most common cause of problems is wrong installation of
the drain pipe as well as the overflow pipe.
We strongly suggest to take particular care when positioning
them during installation.
A clogged drain pipe or a too small drain basin might prevent
salt water sucking from the brine tank, thus causing over-
flowing of water.
Moreover, we suggest to not connect the drain pipe and the
overflow pipe to the same drain basin as, in case of clog-
ging, water might flow back in the overflow pipe causing over-
flowing from the brine tank.
It is advisable to have the salt alarm switched to on when
the softener is in service. This will help to prevent pro-
blems also ensuring proper operations.
