INSTALLATION.

Fit the timer to a cold water tap. The spout of the tap should have a 3/4″ male thread (if not, use an adaptor). Screw the clamp collar of the 3/4″ female fitting onto the tap.  Caution: tighten the collar using hand pressure only. Do not use wrenches or other tools. Connect the watering lines to the respective quick-click or threaded fittings, using the appropriate connectors.
Do not install the water timer inside valve boxes, below ground level, or indoors. Use mains water or have the water filtered. Do not use the water timer with chemicals or liquids other than water. Do not use the water timer with operating pressures lower than 0.5 bar (7.3 psi) or higher than 10 bar (145 psi).
Remember to open the tap and close the timer cover.

FITTING THE BATTERIES.

To insert or replace the batteries, press the lower button down fully and, at the same time, release the front of the timer. Use 2 new, branded 1.5V type AA (LR6) alkaline batteries with an expiry date more than a year away. Insert them into the relevant compartment, respecting the polarity. Replace the batteries within 2 hours of removing them,  otherwise, programming will be lost. Refit the front part of the timer to the back and press, ensuring that the locking tab clicks into place. Important: always replace the batteries at the beginning of each season!
When the batteries are completely flat, the control unit automatically stops its functions and closes the valves. Never replace the batteries during irrigation, otherwise, the water will continue to flow at the end of the cycle.

PROGRAMMING

Selection of watering program. The timer is provided with two lines, A and B, that can be programmed independently.
Press any button once to light up the display and proceed with setting a program. Press button M one or more times to set the irrigation run time (in minutes) until the desired value is shown on display D (e.g. 5 mins). Press button F one or more times to set the irrigation frequency (the interval between successive watering cycles) until the desired value is shown on display E (e.g. 24 hours).
Warning: if the programming entered is set up for the two lines to water at the same time, in order to ensure an adequate flow rate to the system the timer will automatically stagger the time one line opens.

Making changes to the watering program. Repeat the programming procedure as indicated in the “PROGRAMMING – Selection of watering program” section. The new program set in this way will replace the previous one. The line does not have to be turned OFF beforehand.

MANUAL WATERING.

If in the waiting time between one irrigation session and the next, you want to carry out a supplementary session, you can start manual irrigation for 5 minutes. Press the “A- START” and “B-START” buttons simultaneously and hold them for at least 3 seconds; the timer goes into manual mode. To open line A or line B, press the corresponding button: an irrigation session with a run time of 5 minutes that cannot be changed will start. The run time of a manual irrigation session cannot be increased, but its end can be brought forward manually by pressing the A-START or B-START button.
To exit the manual function, make sure that the valves are OFF and then press the A-START and B-START buttons at the same time and hold for at least 3 seconds.

RAIN SENSOR. The timer can be connected to a Rain Sensor, by wire (cod. 90915) or by radio (cod. 90831). When the rainwater in the Rain Sensor exceeds 5 mm, the sensor automatically suspends the irrigation cycle, which then restarts once the water has evaporated.
WIRED RAIN SENSOR. Remove the protective jumper from the rain sensor contacts (no tools are needed). If the Rain Sensor is not going to be used, the jumper must remain in place across the contacts. Fit the connector of the sensor lead. Check that the two-core cable enters the timer by way of the slot provided in the rear of the housing.
