To protect your Water Timer against theft, the GARDENA anti-theft protection 0 (1815 - 00 .791. 00) is available at GARDENA Service.

The bracket on the anti-theft protection is fitted onto the back of the unit. Note that the screw included cannot be loosened once it has been screwed in. The bracket can be used, for example, to attach a chain.

Together with the GARDENA Soil Moisture Sensor (Art. No. 1187) watering is controlled considering the soil moisture.

Assembly

The Soil Moisture Sensor is connected to the connection socket 6 on the back of the control unit (Fig. A).

How it works

If the connected Soil Moisture Sensor indicates there is sufficient moisture then the watering program is either interrupted or not initiated.

Note: Manual watering (function On/Off-man.) is still possible.

11. GARDENA Rain Sensor (Fig. F)

Together with the GARDENA Rain Sensor (Art. No. 1189) watering is controlled considering natural precipitation.

Assembly

The Rain Sensor, as an alternative to the Soil Moisture Sensor, can be connected to the connection socket 6 on the back of the control unit (Fig. A).

How it works

If the connected Rain Sensor indicates an appropriate amount of rain, the watering program is interrupted or not initiated.

Note: Manual watering (function On/Off-man.) is still possible.
