Where to Use Your GARDENA Programming Unit

Intended use

This Programming Unit is part of a watering system and is designed for easy programming of Control Units 1250 in com-bination with Irrigation Valve 1251. These provide the possibility to set up fully automatic, cordless watering systems, which can be designed to cater for varying water requirements of different plant areas and ensure the func-tioning of the system in case of insufficient water supply.
Compliance with the enclosed operating instructions provided by the manufacturer is a prerequisite for proper use of the Program-ming Unit.

Please note

The Programming Unit may only be used for programming the Control Units for GARDENA Irrigation Valves.

For Your Safety

Caution:

Only alkaline batteries of the type 9 V IEC 6LR61 should be used to attain the maximum running time of 1 year. We recommend e.g. the manufacturers Varta and Energizer. To prevent data transfer errors, the battery must be replaced in good time.

LCD display:
It can occur that the LCD display blanks if the outside temperature is very high or very low. This has no effect whatsoever on the retention of data and the correct transmission of data. The LCD display will return when the temperature range is back to the normal operating range.
Programming Unit:
The Programming Unit is splash waterproof. However, protect the unit from jets of water and do not leave it within the watering range.
Control Unit:
The Control Unit is connected to the Irrigation Valve and is splash-proof when the cover is closed. Ensure that the cover is always closed when the Control Unit is positioned near the area to be watered.
Wintering:
Store the Control Unit away from frost at the beginning of the frosty period or remove the battery.

Battery status display

The display includes a symbol to indicate the charge condition of the batteries in the Programming Unit and the Control Unit.
Battery condition in the Programming Unit:
If the voltage falls below a certain level, the symbol Batt. int. will blink until the battery is replaced. If the battery is not replaced after the first blinking of symbol Batt. int. it is possible to switch from the energy-saving to operating mode (approx. 40 times) on the Programming Unit.

Battery condition in the Control Unit: If the battery capacity is exhausted while the Control Unit is connected, then the symbol Batt. ext. will start to blink as soon as data has been transferred (Read) and continues blinking until the Control Unit is disconnected from the Programming Unit. The battery of the Control Units must be changed. If the battery is not replaced and the Control Unit is connected to an Irrigation Valve, no watering programs will be executed. Manual watering using the ON/OFF key of the Control Unit is no longer possible.

Automatic energy-saving stand-by mode

If left idle for 2 minutes, the Programming Unit switches to stand-by mode and blanks the display. The image returns after any key is touched. The main level is shown (time and weekday).

Putting into Operation
