English
The thermostat is an electronic on/of
stat for temperature contr
NTC sensor located either externally or inter
nally within the thermostat.
The thermostat is for flush mounting in a wall
socket. A baseplate for external wall mounting
is available.

WARNING – Important Safety Instructions.
Disconnect the power supply before carrying
out any installation or maintenance work on this
control unit and associated components. This
control unit and associated components should
only be installed by a competent person (i.e. a
qualified electrician). Electrical installation must
be in accordance with appr
regulations.
MOUNTING OF SENSOR
The floor sensor contains a safety extra-low
voltage (SEL
as close to the floor surface as necessary with-
out having to take account of the risk of shock
should the sensor cable become damaged. The
two wires fr
must be additionally insulated, e.g. shrink flex.

lation from coming into contact with the
terminal block for the floor sensor
restrained using cable ties.
It is recommended that the cable and sensor be
placed in a non-conductive installation pipe em-
bedded in the floor (fig. 3). The end of the pipe
must be sealed and the pipe placed as high as
possible in the concrete layer
sensor can be embedded directly in the floor
The sensor cable must be led through a sepa-
rate pipe or segregated fr
The floor sensor must be centred between the
heating cable.
The sensor cable may be extended up to 7 m
by means of a separate two-core cable. T
vacant wires in a multi-cor
example, to supply current to the floor heating
cable must not be used. The switching peaks
of such current supply lines may cr
ference signals that pr
function. If a shielded cable is used, the shield
must not be connected to earth (PE). The two-
core cable must be placed in a separate pipe or
segregated fr
MOUNTING OF THERMOST

the floor in such a way as to allow free air cir
lation around it. Draughts and dir
other heat sources must be avoided (fig. 4). No

power slide button on the cover and the
power switch pin are down.
DO NOT open the thermostat by releasing the
four fixing clips on the back.

importantes. Desconecte la fuente de alimen-
tación eléctrica antes de realizar cualquier
instalación o trabajo de mantenimiento en esta
unidad de control y componentes r
dos. Solamente una persona competente (por
ejemplo, un electricista cualificado) deberá
instalar esta unidad de control y componentes
relacionados. La instalación eléctrica debe r
zarse de acuerdo con las dir
apropiadas.
MONT
El sensor de piso contiene un circuito de segu-
ridad de voltaje extra bajo (SEL
inglés), que le permite ser colocado tan cerca
de la superficie del piso como sea necesario
sin tener que tomar en cuenta riesgo alguno de
electrocución si el cable del sensor se dañase.
Además, es preciso aislar con material termo-
encogible (p.ej. Shrink Flex) los dos alambres
que van del sensor a la caja de montaje.
Para impedir que los cables sueltos de la
instalación fija entren en contacto con el bloque
de terminales para el sensor de piso, será nece-
sario sujetar dichos cables con amarras.
Se recomienda colocar el cable y el sensor en
un tubo de instalación no conductivo incrustado
en el piso (fig. 3). Es preciso sellar el extr
del tubo y colocarlo en la posición más alta
posible en la capa de hormigón. De manera
alternativa, el sensor se puede incrustar direc-
tamente en el piso. Es preciso que el cable del
sensor se pase a través de un tubo separado
