Power module
If loads of more than 15 A are required, expan-
sion is possible using power modules.
The power module is intended to be used with
underfloor heating.
Power modules can be connected to the live
cable and load cable, see relevant sections.
The power module has a built-in two-pole
ground fault circuit interrupter (GFCI).
The power module is for flush mounting in a
wall socket.
Product programme
FLE30-120/240GA (USG-4000)
Power module without sensor (FLS1260)
Warning
To avoid electric shock, disconnect
the heating system power supply at
the main panel before performing
installation and maintenance work
on the power module. Keep the
power module air vents clean and free from
obstruction. This power module is an electrical
device and must be installed in compliance with
national and/or local electrical codes. Instal-
lation must be performed by qualified personnel
where required by law.
The power module is designed for resistive load
only. The resistive load must not exceed 15 A
(1800 W at 120 Vac / 3120 W at 208 Vac / 3600
W at 240 Vac).
Warning
Do not loosen the terminal screws
further than the mechanical stop.
Otherwise this will damage the termi-
nal (fig. 2).
Mounting of the power module
Maximum distance between thermostat and
power modules is 80 ft (25 m.)
Use field wiring cable, recommended min. 20
AWG.
1. Use a screwdriver to release the catch and
remove the front cover (fig. 1).
2. Connect A to C and B to D (fig. 3).
3. Mount the power module in the wall socket.
4. Carefully replace the front cover by first
positioning its upper edge and then clicking
it into place.
Line cable
Delivers power from the service panel (breaker
panel or fuse box) to the power module.
This cable must only be connected to the power
module's line terminals, marked L1 and L2.
1. Connect power cable to terminals 2 and 3
on the back of the power module (fig. 2).
Load cable
Delivers power from the power module to the
heating cable.
This cable must only be connected to the power
module's load terminals, marked load 15 A.
1. Connect heating cable to terminals 1 and 4
on the back of the power module (fig. 2).
2. The detachable cover on the back of the
power module (fig.1) is designed to prevent
uninsulated ground wires from dropping
onto the terminals after installation has been
completed.
Checking the GFCI
It is important that the GFCI is checked for cor-
rect installation and function upon installation
and monthly thereafter.
To check the GFCI:
Press the "TEST" button.
The test is successful if the red LED on the
right of the power module flashes once every
two seconds. If this does not occur, check the
installation.
Press the "Standby/Reset" button to reset the
GFCI.
The red LED will stop flashing and the display
returns to its normal appearance. If the test
fails, repeat the test. If it continues to fail, ask
an electrician to check the installation.
If, during normal operation, the GFCI trips
without the "TEST" button being pressed, there
could be a ground fault! To check whether it is a
ground fault or nuisance tripping, press "Stand-
by/Reset". If this causes the red LED to stop
flashing and stay off, it was nuisance tripping
and the system is operating correctly. If this
does not occur, there is a ground fault! In case
of a ground fault, it is important to have the
installation checked by a qualified electrician
according to local and national regulations.
The red LED on the right of the power module
can indicate four different GFCI states:
1. LED off – NORMAL state.
2. LED flashing slowly (once every two sec-
onds) – TRIGGERED state. Try pressing the
"Standby/Reset" button to reset the GFCI.
3. LED flashing quickly (five flashes per sec-
ond) – ERROR state. Try switching the pow-
er module off and then back on again. If the
power module re-enters the ERROR state,
either the wiring is wrong (a GN exists) or
the unit is defective and must be replaced.
4. LED lit constantly – Internal microprocessor
malfunction or abnormal fault in hardware!
Try switching the power module off and
then back on again. If the LED is still con-
stantly lit, the GFCI is defective and the
power module must be replaced.
Note: The LED lights up briefly without flashing-
during every power-up.

Module de puissance
Si des charges de plus de 15 A sont requises,
une extension est possible en utilisant des
modules de puissance.
Le module de puissance est conçu pour être
utilisé avec des planchers chauffants.
Des modules de puissance peuvent être rac-
cordés au câble d'alimentation et au câble de
charge, voir les sections pertinentes.
Le module de puissance possède un disjonc-
teur différentiel de fuite à la terre intégré à deux
pôles (DDFT).
Le module de puissance est prévu pour un
montage encastré dans une prise murale.

Avertissement
Pour éviter l'électrocution, coupez
l'alimentation du système de chauf-
fage au panneau principal avant de
faire l'installation et l'entretien du
module de puissance. Maintenez les
évents du module de puissance propres et
libres d'obstruction. Ce module de puissance
est un appareil électrique et doit être installé
conformément aux codes électriques nationaux
et/ou locaux. L'installation doit être effectuée
par du personnel qualifié quand la loi l'exige.
Le module de puissance est conçu pour une
charge résistive uniquement. La charge résistive
ne doit pas excéder 15 A (1800 W à 120 VCA /
3120 W à 208 VCA / 3600 W à 240 VCA).
Avertissement
Ne pas desserrer les vis de bornes
au-delà de l'arrêt mécanique. Autre-
ment, cela pourrait endommager la
borne (fig. 2).
Montage du module de puissance

ture et retirez le couvercle frontal (fig.1).
2. Raccorder A à C et B à D (fig. 3).
3. Montez le module de puissance dans le
boîtier mural.
4. Remettez soigneusement en place le cou-
vercle frontal en mettant d'abord en posi-
tion son bord supérieur puis en le cliquant
en place.
