1 PRESENTATION
This thermostat is a receiver that incorporates a
relay with exterior antenna. The receiver is linked
to a transmitter (thermostat) by means of a
communications protocol for remote control.
The
key perrnits configuration of the receiver
or temporary suspension of automatic operation
(Override).
The status of the output relay, as well as the
proper operation of the transmission can be seen
on the upper part of the receiver.
The red light
indicates the contact condition
of the boiler connection.
Lit = "ON"; Out = "OFF".
The yellow light
indicates reception of the
radio transmission.
The green light
"OK"
indicates correct transmitter
operation.

3 INSTALLATION
3. 1 Location
The receiver must be placed high up.
The antenna of the receiver must be kept away
from other conductors (electricity cables, metal
surfaces).
3.2 Fitting
1. Examine the place where you are going to install
the receiver.
2.lf you are using the adhesive tape on the rear,
carefully remove all dust from the surface where
you are putting the receiver and then press
hard.
3.lf you are using the clips, fit them as shown in
the diagram below:
4.Mark the position of the holes on the Wall. Use
a 4 mm diam. drill.
5.Switch off the power supply and connect the
apparatus (para. 4).
3.3 Fitting the antenna
lnsert the cable in the rigid plastic protector for
the antenna and then insert the protector in the
hale until it stops and remains fixed.
4 CONNECTION
4.1 Electrical connections
Before doing anything, switch off the electricity
supply.
Of the wires in the receiver, 2 should be connected
to the live and neutral of the electricity supply
and 2 to the connection for the boiler ambient
thermostat, as shown:
Receiver wire: (Max. 0.75 mm
2
)
BLUE = NEUTRAL
BROWN = LIVE
2 x BLACK = BOILER AMBIENT THERMOSTAT
Usually the connection for the boiler ambient
thermostat carries a jumper which should be removed
before connecting the two corresponding wires.
In the boiler remove the
jumper and connect the
two black wires across
the terminals of the two
corresponding contacts.
5 STARTING UP
Radio waves are propagated in the same way as
light, in straight lines. lndoors the waves are reflected
and weakened by obstacles in their path.
5.1 Configuration / Reconfiguration
Each receiver has its own corresponding transmitter.
This mode of configuration permits the pairing of
the receiver with a transmitter (so there is no
conflict with neighbouring installations).
The procedure is explained in the instructions for
the transmitter.
5.2 Checking the transmission
Use the test mode to check the configuration of
the system and the quality of transmission. (See
transmitter instruction)
5.3 Reception problems
lf the green
"OK"
light flashes, it means that the
receiver has received no information for more
than an hour (and has left the relay open).
Therefore, a communication problem exists
between the transmitter and the receiver.
