Example (not to be used): either you have the micro-switch 2, 7 and 8
placed on OFF, or you have broken the connections 2, 7 and 8 on the
control panel using the template and the coding tool.

You now have a series of "0" and "1" which is the code to be program-
med on the keypad.
Warning: the code "0000000000" is not allowed.

NB: if programming is correct, the red light indicator comes on for 5 s.
NB: while programming, if you press an unauthorised key, or if you
leave more than 7 seconds between entries or if you do not press the
"0" and "1" keys at the same time, the red light indicator flashes and the
programming is incorrect. In this case wait for it to stop flashing before
starting the operation again.
5.6 Checking
G You can check the programming of the installation radio code as
follows:
❍ place the control panel in the test mode near you.
❍ press the test button on the detector for 3 seconds: the red light
indicator will come on (the detector front panel has been removed):
- if the installation radio code is correct, the control panel responds with
a series of audible signals or vocal messages and a light indicator
flashes on the front panel,
- if the installation radio code is incorrect, the control panel responds
with a low-pitched signal and no light indicator comes on.
5.7 Fixing and testing the radio link

G Fold the front panel over the base and clip it on using the locking
pins.
Fit the set screw.

G Press the test button on the detector: if the tested control panel
responds with a series of audible signals and the indicator flashes on
the front panel, then the radio link is OK.

❍ The probe detects a minimum water level of 2 mm by immersion of
its metal flooding contacts.
It can be placed either vertically or horizontally on the ground, as requi-
red, to detect a minimum level of 2 mm.
The vertical position makes it easier to detect higher water levels
(probe raised up from the ground).
Just fix the metal plate supplied and flatten the probe up against it (the
probe will be held in place by its magnet).
❍ Mark on the skirting board (vertical fixing) or on the ground (horizon-
tal fixing) the point where the metal plate is fixed according to the selec-
ted detection height.
If the probe is vertical, the metal plate fixing hole must be placed high
up.
❍ To detect 2 mm water levels, the bottom of the plate must be fixed 1
to 2 cm from the ground.
❍ To detect water levels in excess of 2 mm, you must raise the metal
plate to the required height.
❍ Use the screw and dowel supplied to fix the metal plate.

G The plug and socket unit is placed upstream from the device (e.g.
aquarium) whose power supply it monitors. In the event of a power cut,
the probe responds either after a cut of more than 18 min or a cut of
more than 5 hours, according to your choice. You can choose the dura-
tion by means of a switch placed under the pin part of the plug and soc-
ket unit.
Once you have chosen the duration

❍ The minimum temperature probe measures the surrounding tempe-
rature. We recommend that you place it at least 1.50 meter above the
ground (fixed to an inside wall or placed on a shelf) in a room without
drafts.
The probe must be fixed near the heat source for no-freeze heating
