INSTALLATION
— STEP 3 —
To connect the RC2 receiver, the nor-
mal power cable to the equipment to
be controlled must be “interrupted”
(Fig. 1).
WARNING: Electrical systems
must be set up by qualified and
experienced personnel in compli-
ance with current legislation. As
the cable clamps do not provide
protection against pulling and the
removable cable cap can be separated, the RC2 container must be
positioned where it is inaccessible to the general public. Said contain-
er does not guarantee protection against access to those parts of the
system which are live. If the RC2 receiver is installed outdoors, keep
in mind that the cable holders are waterproof only for round cables
with a diameter of 6.5 to 8.5 mm.
01. Make sure there is no voltage anywhere in the electrical circuits.
02. Cut the power cable to the equipment to be controlled.
03. Open the RC2 enclosure and remove the “cable holding cap” (Fig. 2).
04. Strip the sheath off the two ends of the cable approx. 3 cm, then strip
the single conductors approx. 5 mm.
05. Thread the two cables through the holes in the cable holding “cap”
(Fig. 3).
06. Pull the board out a few centimetres (Fig. 4).
07. Connect the conductors to the terminals (Fig. 5).
08. Fold the conductors (Fig. 6).
09. Push the board back inside the enclosure, making sure that the
stripped sections of cable are not exposed, then slide the “cap” along
the cables until the enclosure is closed tight.
10. The RC2 receiver does not require mounting, it can be positioned

directly in the dedicated compartment. To avoid any risk of water infil-
trations, we recommend positioning it with the cables facing down
(Fig. 7).
WARNING: The enclosure must not be perforated for any reason.

Power Supply
Use terminals 4-5-6 for the main power supply to the receiver (ground, phase,
neutral), as shown in figure alongside “Electrical Connections”.
Connection to the Equipment to Be Controlled
The equipment to be controlled (Max 500W) must be connected to terminals
1-2; No. 3 is the ground terminal.
WARNING
Terminal 6 (Neutral) is directly connected to terminal 1 of the equip-
ment to be controlled, which is therefore not completely isolated from
the power supply line.
Carefully follow all the connection instructions. If you have any doubts do
NOT make experiments but refer to the relevant technical specifications.
Improper connection may cause serious damage to the receiver.

MEMORIZATION OF RADIO TRANSMITTERS
— STEP 5 —
A memorization procedure must be executed in order to enable the transmit-
ter to control the receiver.
WARNING:
• All the memorization sequences described in this chapter are timed, there-
fore they must be performed within the set time limits.
• All the receivers that are within the range of the transmitter can be memo-
rized via radio; it is therefore expedient to power only the receiver involved
in the operation.
You can check whether any transmitters have been previously memorized in
the receiver; this is done by counting the number of beeps emitted when the
receiver is switched on.
Checking the memorized transmitters
3 short beeps Some transmitters are already memorised
2 long beeps Empty memory (no memorized transmitters)
Two different procedures can be followed to memorize the transmitters:
– Mode I: simplified memorization (the transmitter keys are automatically
configured by the RC2 receiver).
– Mode II: advanced memorization (each single transmitter key can be con-
figured for a specific command).

EN
6 – English
Mode I (simplified memorization)
In this mode the functions of the transmitter keys are pre-set. The keys are
associated by pairs: keys 1 and 2 can perform the On-Off commands from
an RC2 receiver, whereas keys 3 and 4 can perform the On-Off commands
from a different RC2 receiver, as shown in the example below.
When the memory is empty (no memorized transmitters) you can proceed to
program the first transmitter in Mode I as shown in table [A].
WARNING: if you press key 1 or 2, this pair of keys will be memorized,
whereas if you press key 3 or 4, this latter pair of keys will be memorized.
Table [A] Memorizing the first transmitter
in Mode I Example
1Power the receiver: you will hear two long
beeps
2Within 5 seconds, press one of the keys
in the desired pair (pair 1-2 or 3-4) on the
transmitter and hold it down 5s
3Release the key when you hear the first of
the 3 beeps confirming the memorization
If the receiver has already memorized one or more transmitters, when it is
switched on you will hear 3 short beeps. In this case you will not be able to
proceed as described above, but will have to switch to the memorization mode
described in Table [B]

EN
English – 7
Example of memorization in Mode I
Key 1 On on RC2 no. 1
Key 2 Off on RC2 no. 1
Key 3 On on RC2 no. 2
Key 4 Off on RC2 no. 2
Even if one or more transmitters have already been memorized in Mode I, ad-
ditional transmitters can be memorized in Mode I, as described in Table [B].
Table [B] Memorizing additional transmitters
in Mode I Example
1Press and hold down one of the keys in
the desired pair (1-2 or 3-4) on the new
transmitter to be memorized (New TX) until
you hear a beep (after approx. 5 seconds),
then release the key
New TX
5s
2Slowly press one of the keys in the
desired pair on a previously memorized
transmitter (old TX)
Old TX
3Once again, press and release the key
on the new transmitter you pressed
according to step 1
New TX
The 3 final beeps signal that the new transmitter has been correctly memorized.
If the memory is full (30 transmitters), 6 beeps will signal that the memory is not
capable of memorizing any additional transmitters.

EN
8 – English
Mode II (advanced memorization)
In this mode, each of the 4 available commands can be associated to a trans-
mitter key, as shown in Table [C].
Table [C] Commands available for memorization Mode II
N° Command Description
1 On-Off The first command switches on the unit, the
next one switches it off, and so on
2Man Present When the key is pressed the relay contact
closes. When the key is released the relay
contact opens
3Timer 1
The contact remains closed for a length of time
ranging from 1 sec to 9 hours (programmable
as shown in Table [G])
4Timer 2 The contact remains closed for a length of time
ranging from 1 sec to 9 hours (programmable as
shown
in Table [G])
In this mode, the memorization procedure is performed separately for each
single transmitter key; this means that 2 keys on the same transmitter can be
memorized for two commands to the same receiver, or to command different
receivers as illustrated in the example below:
Example of memorization in Mode II
Key 1 On-Off on RC2
no. 1
Key 2 Timer1 on RC2
no. 2
Key 3 Timer2 on RC2
no. 3
Key 4 Man Present on
RC2 no. 3

To memorize the transmitters in Mode II, refer to Tables [D] and [E].
Table [D] Memorizing the first transmitter
in Mode II
Example
1As soon as the receiver is powered you
will hear 2 long beeps
2Within 5 seconds, press the desired
key on the transmitter to be memorized
and hold it down until al 3 beeps have
sounded, then release the key
3Within 3 seconds, press the same key
on the transmitter as many times as the
number corresponding to the desired
command: 1 = On-Off; 2 = Man Present;
3 = Timer1; 4 = Timer2
X1...X4
4After approx. 3 seconds you will hear a
number of beeps corresponding to the
selected command X1...X4
5Within 2 seconds, press and release the
same key to confirm the programming
The 3 final beeps signal that the new transmitter has been correctly memorized.
During step 4, if you do not hear the number of beeps corresponding to the
desired function, wait 10 seconds before abandoning the procedure, then try
again.

Memorizing a new transmitter like a previously memorized transmitter
It is possible to memorize a new transmitter so that it operates exactly like a
previously memorized one. If the old transmitter was memorized in Mode I,
the new one will also operate in Mode I and a single memorization stage will
be required. If the key on the old transmitter was memorized in Mode II, also
the key on the new transmitter will be memorized in Mode II and will perform
the same function. If you wish to memorize more than one key you will have
to perform a memorization procedure for each key.

Programming the Timers
The RC2 receiver features two independent timers (Timer1 and Timer2) for
automatic relay deactivation after a set time delay.
The deactivation time can be brought forward, compared to the timer setting,
by maintaining the “timer” command active for more than 3 seconds or by
giving an “Off” command.
The factory or default settings for the two timers are 1 minute (Timer1) and 10
minutes (Timer2) respectively.
The time settings can be programmed separately for each of the two timers,
from a minimum of 1 second to a maximum of 9 hours. Once the timer has
been programmed, every command associated with it will activate the relay
for the set time interval.
In order to program the timers you need to have a transmitter memorized for
timer control, then follow the steps in the table [G].
Table [G] Programming the Timers Example
1Press and hold down the transmitter
key associated with control of the timer
you wish to program. The relay will be
activated (On)
“Relay ON”
2Hold the key down, after approx.
3 seconds the relay will be deactivated
(Off) 3s “Relay OFF”
3Hold down the same key for approx. 10
seconds, until the relay is activated again
(On). The time measuring stage starts at
this point. Release the key
10s “Relay ON”

EN
English – 13
4When the time you wish to set has
elapsed, press the key associated with
control of the timer. The relay will be
deactivated (Off) and the measured time
will be memorized
“Relay OFF”
3 long beeps will signal that the time has been programmed successfully;
the following 1 or 2 short beeps indicate whether timer1 or timer2 has been
programmed.
Clearing the Receiver Memory
There may be cases when the RC2 receiver memory has to be cleared.
The memory can be cleared using:
– non-memorised transmitters or those which have been memorised for
“Timer” commands starting from point A.
– A previously memorized transmitter, starting from step N. 1
The following items may be erased:
– Transmitters only, proceeding up to step 4
– All the data (transmitters and timers), completing the procedure up to
step 5.
Table [H] Clearing the Memory Example
➨A With the receiver not
powered, remove the
jumper from the board
(after clearing the
memory, the jumper must
be reinstalled).
B Power the receiver and wait for the initial
beeps

EN

➨1 • With the transmitter in mode I or
not memorized:
Press and hold down key 2 or key 4 on a
transmitter previously memorized in mode
I until you hear a beep (after approx. 5
seconds), then release it.
• With the transmitter in mode II (On/
Off or timer only):
For On/Off with open relay (Off), press the
key to activate it (On), release the key,
press it again and hold it down until you
hear a beep (after approx. 5 seconds),
then release the key.
For timer with open relay (Off), press the
key to activate the relay (On), hold down
the key until the relay is deactivated (Off)
and you hear a beep (after approx. 5
seconds), then release the key
