8. Close cover and let snap lock
9. Plug the mains plug of the 24 V (AC) power sup-
ply unit into a mains socket.
After this it is necessary to set the date and time
(see 4. OPERATION Setting the date and
time).
Master Channel:
To connect the master valve:
The master channel M is activated, as soon as
a valve is activated.
You can connect a central valve upstream of the
other valves to act as a master valve.
Connecting the valves [ Fig. I3 ]:
The example shows the connection of 2 valves
Art. 1278 in the Valve Box Art. 1255 to the
Watering Controller 4030 / 6030. As the output
of the Watering Controller is 24 V AC (alternating
current) for switching the valves, it is does not
matter which of the two cables of a valve is
inserted into C.
Labelling the valves:
!
Label the valves (1 – 6), so that the channels
(CHANNELS 1, CHANNELS 2, ...) of the
Watering Controller can be clearly assigned
to the valves.
Connecting the valves to the Valve Box:
" Connect one cable of the valve V1 to the cable
terminal 1 of the valve box.
§
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).
$
Connect one cable of the valve V2 to the cable
terminal 2 of the valve box.
% 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:
& 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.
/
Connect the cable terminal of channel 1
CHANNELS 1 to the cable terminal 1 of the
valve box.
(
Connect the cable terminal of channel 2
CHANNELS 2 to the cable terminal 2 of the
valve box.
Other channels can be connected similarly
to CHANNELS 1 and CHANNELS 2.
Cable cross­section 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 dis-
tance of 30 m, the cross section is 0.5 mm
0.75 mm for a distance of 45 m. No more than
2
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. Up to 6 valves
2
can be connected using this cable. The connec-
tion cable can be connected so that it is water-
tight using the cable clip Art. 1282.
Wall-mounting the Watering Controller
[ Fig. I4 ]:
The two screws (not supplied) for attaching the
Watering Controller have to be screwed into place
80 mm apart and the screw head diameter must
not exceed 8 mm.
