Introduction
Our thanks for the confidence shown in purchasing this product. Please
read this instruction manual carefully before programming the device, and
keep it handy for future reference: each section will provide all the neces-
sary information on how to perform the single steps correctly.
This device has been designed and manufactured exclusively for the pro-
gramming of watering time by adults with experience and knowledge. Any
use other than that described in this manual is considered improper: the
manufacturer acknowledges no liability for damages arising from improper
use, which will also void the guarantee.

Reminders
1. Use only two AAA (LR03)1.5V Alkaline new batteries, with an expiry date
exceeding one year. Follow the instructions of the battery manufacturer.
Do not power the water timer with sources other than those specified.
2. Replace the batteries at the beginning of each season.
3. During winter and/or when not in use, always remove the batteries and
store the water timer in a dry place at a temperature no lower than 3 °C.
4. Periodically, check the integrity of the seals fitted to the transparent cov-
er and to the cap of the battery housing.
5. Periodically, check that the electrical connections of the battery are firm
and secure.
6. Do not let water freeze inside the product. At the end of each season,
it is recommended that the manual valve upstream is closed and the
system is drained using the manual opening of the control module.
7. Make certain that children and animals cannot play with the water timer
or any of its parts.
8. It is good policy — when the water timer is put into operation for the
first time — to make certain that the programmes run correctly.
9. Avoid harsh tugging of hoses and fittings connected to the water timer.
10. Do not use the water timer with operating pressures lower than 0.2 bar
(2.9 psi) or higher than 12 bar (174 psi).
11. Do not fit the water timer inside buildings.
12. Do not use the water timer with chemicals or liquids other than water.
13. Do not submerge the timer in water or other liquids.
14. Do not let the housing and the internal parts of the water timer come
into contact with chemical agents (e.g. aggressive detergents, chlorine,
fertilizers, etc.).
15. When not programming, keep the cover of the valve box closed to
protect it from atmospheric agents and moisture.

General specifications
The water timer allows you to easily set the time, watering run time and
date of four watering lines.
The programming of the water timer allows you to satisfy the requirements
of different plants according to their species and environment.
The water timer is powered by two AAA (LR03) 1.5V Alkaline batteries that
must be replaced at the start of each season and are sufficient, for at least,
the entire watering season.
• 3/4” threaded male water intake connector
• 3/4” threaded male line connector
• Power supply: 2 AAA (LR03) 1.5V Alkaline batteries
• Programmable lines: 4
• Watering frequency:
two watering programmes, Aand B, which ope-
rate independently from each other on one or more of the 4 lines .
• Manual function pre-set at 5 minutes, for system testing and mainte-
nance which does not alter the chosen programmes.
• Rain sensor connection (Rain Sensor RF - optional)
• Flow rate for each individual valve:
0.2 bar 4,5 l/min
1 bar 16 l/min
2 bar 22 l/min
2.5 bar 25 l/min
3 bar 27 l/min
4 bar 31 l/min

In order to operate the water timer requires two AAA (LR03)1.5V Alkaline
batteries that must be replaced with two new charged batteries at the start
of each season and are sufficient for, at least the entire irrigation.
To install or replace the battery, proceed as follows (
fig.2 ):
• Unscrew the two screws on the valve box cover (
1
), remove them (
2
)
and remove the cover (
3
).
• Unscrew the plastic cover on the water timer (
4
) and lift it up (
5
).
• Take out the water time (
6
) .
• Unscrew the battery compartment plug (
7
), take out the bat-
tery-holder (
8
), and if present, remove the drained batteries.
• Fit the new batteries in the holder, observing the correct polarity (
9
)
• Replace the battery-holder into its housing (10) and screw down the
plug checking that the seal is correctly placed in its seat (11).
• Insert the water timer into its seat (
12
), screw the cover back on (
13
),
close the valve box with its cover (
14
) and secure it using the designated
screws (
15
) (
16
)
Notes:
• Only use new AAA (LR03)1,5V Alkaline batteries , with an expiry date
exceeding one year and that have never been used.
• Replace the batteries at the beginning of each season.

Installation
The valve box is to be installed outside, buried at ground level or resting on
the surface, ensuring that the cover opening is free so that the valve inside
the box can be programmed easily.
If installed below ground, do not place it in areas which are frequently wal-
ked over or passed over by mechanical means (eg. ride-on lawn mowers).
fig.3C
fig.3Bfig.3A

EN
64
Installation
If installing below ground, use a spade to make a hole of a sufficient size
to hold the valve box and tracks where the 4 watering line pipes will pass.
Place an even layer of shingle on the base of the hole and position the
valve box ensuring that it is stable and level (
fig.4 ).
If installing above ground, rest the valve box on a stable and level surface,
ensuring that the pipes coming from the 4 watering lines do not obstruct
the passage of people or cause any risk of injury.
Once the valve box has been positioned, make the hydraulic connections as
indicated on the following pages: depending on individual requirements, it
is possible to connect the valve box with pipes of different diameters using
the specific fittings (not supplied). See solutions

Installation
Open the transparent cover of the water timer
and carry out a functional test by activating ma-
nual watering (please refer to section test/manu-
al watering on page 92 ): if the test has a posi-
tive outcome, close the cover.
The control module is fully watertight
and will function even when under
water at a depth of up to one metre
(ingress protection IP 68).
To obtain product water tightness, the transparent cover must be scre-
wed down completely with the seal well positioned in its seat ( fig.5
part
1
).

• Do not use the water timer with chemicals or liquids
other than water.
• Do not use the water timer with operating pressures
lower than 0.2 bar (2.9 psi) or higher than 12 bar
(174 psi).
• Size the system on the basis of the flow rate of each
individual valve

Also close the valve box cover fig.6
and, if installed below ground, fill the
hole with soil making sure that the
valve box cover is left free for inspec-
tion and programming activities.
