7. Changing the Battery / Testing the Battery
A
To ensure the Water Timer runs safely, only a 9 V alkali-
manganese battery (alkaline) type IEC 6LR61 must be used.
If the battery voltage falls below a
certain level
the
Batt
. indicator appears.
It is possible to initiate watering manually
even if the battery capacity is too low
(valve no longer opens), but programmed
watering times, however, are not initiated.
Even if the
battery capacity is too low
to run a program, if the valve is
open it will be closed.
The battery voltage is tested
between the opening and the closing
pulse.
In this way you can test the capability of the battery
at any time.
To do this, press two times the
On / Off-man.
key. If the valve closes and
the
Batt
. indicator does not appear then the battery is functioning. If the
display disappears and only the
Batt.
indicator is visible, the battery has
to be changed.
A
Previously set data is lost when replacing the battery.
Program the Water Timer subsequently again.
For notes on changing the battery see “Inserting the Battery”.
Hint !
Please return the flat battery to a GARDENA dealer or dispose of it
properly at your nearest recycling centre. Only dispose of battery
when
it is flat.
8. 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.
.
To prevent water penetrating the battery compartment the Water
Timer must only be mounted in a perpendicular position with
the sleeve nut pointing upwards.
.
Program the Water Timer with the tap turned off. In this way
you can avoid getting wet when trying out the manual On / Off
function. You can remove the control unit from the housing to
program the Water Timer.
.
The Water Timer must only be used outdoors.
Warning ! The Water Timer must not be used indoors.
