7. Changing the Battery
To ensure the Water Timer runs safely, only a 9 V alkali-
A
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

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 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 appears, the battery has
to be changed.
Previously set data is lost when replacing the battery.
A
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.
