11. Battery
11.1 Status indicator
If the battery capacity falls below a certain level, a warning signal sounds
every 15 seconds. The programs you have set are not run. The water flow
cannot be opened manually. If a valve is open, however, it will be closed.
11.2 Changing the battery
If the battery capacity is too low (the warning signal beeps every
15 seconds), you must change the battery. To do this, the water timer
must be removed from the tap.
Important : Changing the battery deletes the data you have set.
To change the battery :
1. Insert the battery in the battery compartment
2. Set the Run Time control knob
3. Reset the watering data as described in "Setting the watering data".
3
If the Run Time knob
is not turned to Reset, 5 seconds after the
battery was inserted the current Run Time
shall be accepted. This is confirmed by a double beep.
Note : The time the battery was changed is taken to be the starting time.
To ensure that the water timer works properly we recommend that you
insert a new battery at the beginning of every gardening season, or at
the latest after a year.
Important ! Please dispose of used batteries properly at the appropriate
communal waste disposal site. Only dispose of batteries when flat.
12. Notes on Safety and Operation
The minimum water output to ensure that the Water Computer
.
functions correctly is 20 - 30 l / h.
For example, at least 10 x 2-litre Drip Heads are required to
control the Micro-Drip-System.
The Water Timer must be stored in a dry place away from frost
.
before the frosty season begins.
The max. temperature for the water flow is 40 °C.
.
The minimum operating pressure is 1 bar, the maximum opera-
.
ting pressure is 12 bar.

For functional safety reasons, only use a 9 V alkali-manganese
.
battery.
The water timer beeps at intervals to indicate that the battery
.
capacity is too low until the battery is flat. When the water timer
is beeping the valve is no longer opened. To ensure that the water
timer works properly a battery with low capacity must be exchan-
ged.
We recommend fitting the water timer with a new battery at the
.
beginning of every gardening season or at the latest after a year.
The functional safety of the water timer depends on the capability
.
of the battery. The water timer will only run for approx. 1 year if
the new alkali-manganese battery has a nominal voltage of at least
9 V. Check the battery before you buy it.
To prevent water penetrating the battery compartment, the Water
.
Timer may only be installed in a perpendicular position with the
sleeve nut pointing upwards.
The control unit must be attached to the Water Timer during
.
operation.
Warning ! Only use the water timer outdoors.
.
The water timer is not approved for indoor use.
Check the filter in the sleeve nut
.
sary.
Avoid tensile strain. Do not pull the hose connected to the Water
.
Timer.
Only use clear fresh water.
