Fix the timer to a wall in a covered location, sheltered from weather and splashing water; ambient temperature
between 0 and 50 °C. Do not install the timer outdoors or in underground valve box.
Before connecting the timer to the electrical power supply, install the 9V backup battery, which will ensure that the clock
setting and programme data will not get lost in case of a mains power failure. Open the snap-t cover of the battery pocket.
Pull out the cable (and the old battery, in case of a replacement). Connect or replace the battery. Reposition the cable and
the battery in the pocket and close the cover. If the back-up battery is missing or at, the message “ ” appears.

The Master Valve (main valve) is an optional safety valve, installed upstream of the line valves; it is opened auto-
matically so that the system is only powered while watering operations are in progress.
1
Pass the required electrical cables through the protective pipe. The recommended cross-section for all
cables is 1.5 mm
2
with a length of less than 350 m: above this limit, the cross-section needs to be increased.
2 Connect the cables to the relative valves (including the Master Valve if used).
3 Join the individual wires coming from any valve terminal with a wire from the water timer (common for the
valves).
4
Remove the cable protection cover by unscrewing the self-tapping screws and make the connections to the
water timer terminal board by inserting and tightening the ends which will have been stripped by 5-6 mm;
- the common wire coming from the valves to the terminal C,
-
the wire coming from the second terminal of each line valve to terminals from 1 to 4 (6 if there are 6 lines),
- the wire coming from the second terminal of the Master Valve (if used) to the terminal MV.
If a control pump is used, connect the two terminals A1 and A2 of the relay coil to the terminals MV and C
respectively, and complete the connections.
The solenoid valves and relay used must operate at 24 VAC - if a pump is used, this must only be connected
via a relay which will operate a contactor.
The Master Valve is used as an alternative to the pump relay and vice versa.
5 Attach the water timer to the bracket.
6 Insert the stripped ends (stripped by at least 5-6 mm) of the transformer cable into the two terminals AC.
7 Attach and secure the cover using the two 2.9x13 self-tapping screws.
8 Plug the transformer into the power socket.
Only use the transformer supplied with the water timer.
