7. Changing 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
during the opening pulse.
In this way you
can
test the capability of the battery at any time.
To do this, simply
press the
On / Off-man.
key. If the valve opens and the
Batt
. indicator does
not appear then the battery does not have 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”.
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.
.
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.
