Where to Use Your GARDENA Watering Controller

Proper use
The watering controller is suitable for indoor and outdoor use.
This Watering Controller is part of a garden irrigation system.
Recommended accessories: the watering valve (24 V) Art. 1278, the valve boxes Art. 1254 / 1255 and the connection cable Art. 1280 and the cable clips Art. 1282.

These products allow you to set up fully automatic irrigation systems, which can be designed to cater for varying water requirements of different plant areas and ensure that  the entire system functions correctly in case of insufficient water supply.
Compliance with the operating instructions provided by GARDENA is a prerequisite for proper use of the Watering Controller.

Please note
The Watering Controller must only be used for controlling 24 V (AC) valves.

Safety Instructions

Watering Controller:
The Watering Controller must only be operated with the 24-V (AC) power supply unit provided.

• Protect the 24-V (AC) power supply unit from moisture when connected.
  The Watering Controller (without power supply unit) is splash proof.
  → Avoid, however, spraying the Watering Controller directly with water.
  To prevent loss of data if a power failure occurs, only use a 9 V alkaline battery IEC 6LR61 to buffer data. We recommend using batteries manufactured by Duracell and  Energizer (do not use rechargeable batteries).

Putting into Operation

Connecting your Watering Controller:

Before programming your Watering Controller, install a 9-V battery to prevent loss of data if a power failure occurs.

1. Raise cover 1 and pull downwards.

2. Insert the cable of the power supply unit into the 24VAC terminals and screw tight.
   The wiring diagram is located inside the cover 1.

3. Insert cables for the valves (e. g. 7-wire GARDENA connection cable Art. 1280 for up to 6 valves) in the clips with the numbers and C and screw tight. (see also  “Connect valves” ).

4. If necessary, insert the sensor cable (e. g. GARDENA moisture sensor Art. 1187 ) in the sensor connection 3.

5. If you intend to use the master channel (e. g. Art. 1273), insert the cable for the master channel into the terminals labelled M and C (Pump) and screw tight. (see “Master  Channel” ).

6. Insert battery into the battery compartment 2.
   Observe correct polarity.

7. Push cover on to the connection box.

8. Plug the mains plug of the 24 V (AC) power supply unit into
   a 230 V mains socket.
   After this it is necessary to choose between a 24 hour or 12 hour display and the time must be set (see 5. Operation “Setting the time” ).

Connect extension module:

The GARDENA extension modules Art. 1277 with 2 channels are available as an optional extra. Up to 4 expansion modules can be connected and in this way 12 channels  can be controlled via the base unit.

1. Break off bar 4 from the watering controller (or already connected expansion module).

2. Insert connection links 8 into the watering controller (or an expansion module already connected) and push the expansion module on.

3. Secure expansion module via the clamps 9.

4. Connect the expansion module cable 5 using the connector 6 (if connecting another expansion module, connect the expansion modules using the expansion module  connector
   The expansion modules are detected immediately by the watering controller when connected.

5. Push on cover of watering controller and the expansion module.

Master Channel:
The master channel is a channel that can be operated at the same time as other channels. This is important, for example, if you want to use a pump to supply your irrigation  system with water and if the pump should always be activated each time an irrigation valve is activated. The master channel closes 20 seconds before the end of the program  so that the system is not under pressure.
The pump can be operated, for example, using the GARDENA Pump Control Art. 1273 that is connected to the master channel.

Connecting valves:
Example: with 2 valve boxes V3 (Art. 1255)

Labelling the valves:

1. Label the valves (1 – 6), so that the channels (1 – 4) of the Watering Controller and the channels (5 and 6) of the expansion module can be clearly assigned to the valves.
   Connecting the valves to the Valve Box:

2. Connect one cable of the valve V1 to the cable terminal 1 of the valve box.

3. Connect the other cable of the valve V1 to a cable terminal C of the valve box (All 4 cable terminals C are interconnected and equivalent to one another).

4. Connect one cable of the valve V2 to the cable terminal 2 of the valve box.

5. Connect the other cable of the valve V2 to a cable terminal C of the valve box.
   Other valves can be connected similarly to V1 and V2.
   Connecting the Watering Controller to the Valve Box:

6. Connect a cable terminal C of the Watering Controller to a cable terminal C of the valve box. Both cable clips C are connected to each other and equivalent.

7. Connect the cable terminal of channel 1 to the cable terminal 1 of the valve box.

8. Connect the cable terminal of channel 2 to the cable terminal 2 of the valve box.
   Other channels can be connected similarly to the channels 1 and 2.

Cable cross-section of the connection cable:
The maximum permissible distance between the Watering Controller and the valve depends on the cross-section of the connection cable. For a distance of 30 m, the cross  section is 0.5 mm2 and 0.75 mm2 for a distance of 45 m. No more than 3 valves must be in operation at the same time.
The GARDENA connection cable Art. 1280 is 0.5 mm in size and is 15 m long. The connection cable can be connected so that it is watertight using the cable clip Art. 1282. 2

Mounting wall bracket:

V If using the expansion module 2040:
Hold the drilling template supplied against the wall and mark the holes with a pen.

1. Screw the mounting plate 8 for the watering controller (and, if applicable, the mountings for the expansion modules) to the wall.
2. Hook the watering controller (with expansion module, if applicable) from above into the mounting plate 8 so that its back is against the mounting plate (and into the  mountings for the expansion modules if applicable).
