Receiver for home automation
The active antenna, together with one or more relay modules, is the receiving
part of a wireless system intended to be used for temperature regulation.
The device connects with the relay module through a 6-pin data cable and
communicates with the RS485 bus. Every relay module can extend the
communication bus module by means of additional modules and relevant data
Up to a maximum of 10 relay modules can be connected to the same active
The device can be configured to work as a repeater, that is re-transmitting
the radio commands received from one or more wireless devices that have
difficulties in reaching the receiver. In this way, it is possible to solve problems
of transmission distance in difficult environments or to double the distance that
can usually be reached.
Alternatively, the device can be connected to a PC or a home automation
controller instead of a relay module, with which it will communicate through the
RS485 bus. In this way, it is possible to receive all the commands coming from
the radio thermostats to the home automation controller, which will manage
the control outputs of the heat regulation system and a user interface, if any.
The relay modules provide the power supply in direct current through the data
cable. If the device is used as a repeater or receiver connected to a PC, it must
receive the power supply through the two terminals duly shown with 1- and
2+ (Fig. 4).
Working as a repeater
The device is factory configured to operate as an active antenna.
To configure the device as a repeater, remove the JP1 jumper and leave JP2
inserted (as shown with B in Fig. 5). The device works as a repeater and no
longer communicates with the relay modules. In this configuration, 12VDC
power supply must be supplied to terminals 1- and 2+.
Carry out the self-learning procedure of the device’s address, on which you
want to repeat the radio command:
- Turn on the thermostat or other transmitting device and set it up in “test”
mode. (This means that it will continuously transmit an ON command,
followed by an OFF command after 3 seconds).
- Press the “self-learning” key for a second, shown with 4 in Fig. 4. This enables
the self-learning procedure and the LED 1 in Fig. 1 will flash quickly in orange.
The self-learning key can be pressed, even without removing the cover, using
a small screwdriver through the slots on the front, as shown with 4 in Fig. 1.
- As soon as a test radio command is received, the LED remains lit in orange
and will stay lit for 7 seconds. During this time, the device waits for other
test commands. If test commands are received from other radio devices, the
device will save the command received with the highest power. This enables
the learning of the address of the device that is physically the closest.
- Once the time has expired in the previous point, the address learnt will be
saved in a non-volatile memory and the LED will flash in a green-red-green-red
sequence. The procedure ends automatically and the device starts to work as
a repeater.
- To complete the installation of the repeater, the self- learning procedure of
the command address re-transmitted by the repeater must be also carried
out on the receiver. To do this, just leave the transmitting thermostat in the
test mode, whose commands will be repeated by the repeater just configured.
In order for the receiver to learn the commands coming from the repeater
and not from the thermostat, you need to make sure that the repeater has
been positioned (even temporarily) halfway between the receiver and the
thermostat or that the repeater has been positioned closer to the receiver.
Check that the receiver receives the commands repeated by the device. The
output relay should immediately start to enable and disable itself every three
seconds, following the commands given by the transmitter.
Repeat the procedure for every transmitter on which you want to repeat the
command. Up to 50 transmitting addresses can be saved and repeated.
If no address has been learnt in the memory, the LED flashes quickly in green to
indicate an error status as the device will not repeat any command.
Once it has learnt at least one address, the LED remains lit in a fixed green
colour to show that the device works regularly as a repeater.
The LED will light up in orange for a while to show that a command has been
received; whereas it will light up in red for a while to show that a command
has been re-transmitted.
If there is a problem with radio communication during the self-learning, it will
not be able to reach the third point of the procedure, the LED will continue to
flash in orange and the procedure will be interrupted automatically after 30
The procedure can be interrupted also by pressing the self-learning key again.
It is recommended to repeat only the commands of the transmitters that
effectively have a range problem in contributing towards keeping the band as
free as possible.
Deleting a repeated address
There are two possibilities if you want to delete an address that has been
learnt, so that the commands of the corresponding transmitter are not repeated
any more: deleting the last address that has been learnt or deleting all the
To delete the last address, press the self-learning key and keep it pressed
down, the LED flashes quickly in orange and release the key when the LED
turns red. The deletion that has been executed is shown on the LED with a
green-red-green-red sequence.
To delete all the memory press the self-learning key and keep it pressed down
until you see the green-red-green-red sequence on the LED.
Working as a receiver for the PC
The device can be connected to a PC or a home automation controller, with
which it will communicate by means of the RS485 bus. To configure the device
as a receiver, leave the JP1 jumper inserted and remove JP2 (as shown with
C in Fig. 5). The device works as a receiver and no longer communicates with
the relay modules. In this configuration, 12VDC power supply must be supplied
to terminals 1- and 2+.
For further information on the operating mode and the communication protocol,
please contact your local distributor.
The two-colour LED 1 usually remains on in green and fixed to shown that
the device is powered and operational.
Receiver mode for PC
Fixed green: device powered and ready to receive.
Fixed orange (short): a radio command was received and sent to the PC.
Flashing red (fast): serial communication error.
The receiving system consists of at least one active antenna and a relay
The best place to install the device should be decided based on the following
- The antenna was designed within a small enclosure so that it could be easily
installed where the radio signal is the strongest.
Repeater mode
Fixed green: device powered and ready to receive/transmit.
Fixed orange (short): a radio command was received.
Fixed red (short): a radio command was re-transmitted.
Flashing green (fast): no address to be repeated was learnt.
Flashing orange: self-learning of the channels to be repeated.
Active antenna mode
Fixed green: device powered and ready to receive.
Fixed orange (short): a radio command was received and sent to the relay
Fixed red: association mode ongoing in the relay modules.
Flashing red (fast): communication error with relay module.
Any flashing colour (slow): repetition of the most significant error coming
from a relay module of the chain.
The LED may flash continuously to shown that there is an error, for example, in
working as an active antenna. If there is an error in one of the channels of the
connected modules, this is also signalled by the device’s LED.
The statuses shown by the two-colour LED vary according to the operating
It is often the case that the place where the relay module is installed is not a
good position for the antenna.
- The worst case scenario is when the relay module is installed in a metal
frame. The antenna must definitely be positioned completely outside the
metal frame.
- As the radio signals are strongly reduced by metal shielding, the antenna
should be positioned as far away as possible from metal grilles or objects.
- Attention must also be paid to the type of wall on which the antenna is fixed.
It must not be metallic or have an inner metal structure.
- The radio signals within a building are reflected by walls, floors, furniture
and other objects. Therefore it may be the case that some areas of a building
have no reception, while other zones have a very good reception. Even moving
the antenna only by half a meter can cause a considerable improvement in
the reception. Once the position where the antenna will be installed has
been chosen, you need to check the system to make sure that the signals
are received from all the transmitters. Consult the documentation of the
thermostats to carry out this operation. Once the system has been checked
successfully, carry out the final installation of the device.
In order to finally install the device follow these directions:
- Remove the cover using the screwdriver as a lever on the plastic tabs, shown
with 2 in Fig. 1-2, pressing down lightly between the tab and the hole in
the plastic, without pushing down directly on it to avoid it breaking. Fig. 2
shows the cross-section of the plastic enclosure to emphasize how to use the
screwdriver correctly.
- Once the best place for installation has been identified, fix the bottom of
the device onto the wall using two screws and the two holes spaced 60 mm
When working with tools in the vicinity of the screw holes, be careful not to
damage the internal electronic circuits.
- Select the operating mode of the device. (See the “OPERATION” paragraph.)
- Connect the device to the relay module, inserting one end of the connection
cable provided on the data connector and the other end on the connector
- When deciding on a correct position, make sure that the radio signals
transmitted are received correctly by the receiving unit.
- Device installation and electrical connections must be carried out by
qualified personnel and must comply with the laws in force.
- Before making any connections, make sure the mains power is

marked with the label “SIGNAL IN” on the relay module.
- It is not necessary to connect the external power supply when the device is
connected to a relay module as the latter supplies power through the data
- If you only use the device as a repeater or receiver connected to a PC, that
is to say not connected to a relay module, it is necessary to connect an
external power supply to terminals 1 and 2, respecting the polarity. Use a
mains adaptor with direct current output having voltage and output current
as stated in the “Technical data” paragraph.
- Close the device by positioning the cover on the bottom and press down
lightly until the four plastic tabs click.
