WARNINGS
PRODUCT DESCRIPTION AND APPLICATIONS
— STEP 1 —
• Before proceeding with the installation, make sure the product is suit-
able for its intended use. Pay special attention to the data provided in the
“Technical Characteristics” chapter. NICE disclaims liability for any dam-
age resulting from uses of the product other than those described in this
manual.
• Protect the product’s internal components from contact with water and
other polluting substances. Keep it away from heat sources and do not
expose it to open flames. If any of these conditions occur, stop using it
immediately and call NICE customer service.
• Disconnect the power supply before proceeding with the installation opera-
tions.
• The packaging materials must be disposed of in compliance with the regu-
lations locally in force.
— STEP 2 —
The RC2 receiver, used in combination with the GTX4/GTX4C transmitters,
is suitable for the remote control of single-phase equipment powered by the
mains voltage, with up to 500W power.
The possible commands are On/Off, “Man Present”, Timer 1 and Timer 2.
The receiver operates at a frequency of 433.92 MHz and can memorize up to
30 “GTX4/ GTX4C” transmitters.

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]

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.

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
