DESCRIPTION
______________________________________________
The conventional inputs module, depending on the status of the two dedicated inputs, sends radio
controls to the RF SYSTEM series actuators, such as:
• 3A output modules,
• 16A output modules,
• motor control modules.
Green signal

LED
Channel 1 input (white
wires)
The module is provided with a green signal LED (A). The two inputs (B-C) are dedicated to the
connection of contacts, without potential, of control appliances (buttons, switches, sensors, etc.). The
module is powered at 230 V.
A rotary switch (D) is used to select the operating mode, valid for both input channels.

CONFIGUR TION
________________________________________________
All that is required to make the association with an output module is to close the input contact of the
channel to be combined after having set the output module to learn configuration.
The input channels can be associated independently to distinct actuators, except in the case when
COMBINED INPUTS is to be used. In this case both channels must always be associated to each
output module.
Each association can be made independently of the operating mode selected at that time.
OPER TING
______________________________________________________
The module's operating mode is determined by the position of the rotary switch.
Combined inputs mode
The combined inputs mode (switch in position 0) is used to connect the module to a pair of
monostable buttons or an interlocked double button, which must operate in combination.
By connecting the contacts of an interlocked double button to the inputs, it is possible to:
• in combination with a 3A or 16A output module, configured for BISTABLE operation, for example
to control lights, switching on the lights (ON) by pressing the button connected to channel 1 and
switching off the lights by pressing the button connected to channel 2;
• in combination with a motor control output module, controlling the raising of a roller blind by
pressing the button connected to channel 1 and its lowering by pressing the button connected to
channel 2. The roller blind is stopped by pressing either of the two buttons when it is in motion.
In combined inputs mode, combinations are possible with actuators configured for MONOSTABLE
operation (ON when the channel contact is closed and OFF when it is opened) and TIMED (ON when
the channel contact is closed and automatic off when the set time has elapsed).
Status mode
The status mode (switch in position 1) is used for connecting the module to the NA contacts for
automatically controlled device. For example, by connecting one input to the contact (NA) of a clock,
it is possible to:
• in combination with a 3A or 16A output module, configured for BISTABLE operation, start/stop the
watering of a garden depending on the status of the contact (closed/open).
For example, by connecting the other input to the contact (NA) of a twilight sensor, it is possible to:
• in combination with a motor control module, control the raising/lowering of a sun blind
depending on the status of the contact (ON/OFF).
In status mode the module periodically (10 minutes) retransmits the command even if there are no
status changes to the input contact. Repetitions of messages are ignored by the motor control actuator.
Combinations with actuators configured other than as described above are not possible in status mode.

Inversion mode
The inversion mode (switch in position 2) is used to connect the module to NA contacts to generate
cyclic ON-OFF commands. For example, by connecting a button (NA) to an input, it is possible to:
• in combination with a 3A or 16A output module, configured for BISTABLE operation, activate and
disactivate charges, cyclically, each time the button is pressed.
By connecting another button to the second input, it is possible to manage a further group of charges
in the same way. Combinations with actuators configured other than as described above are not
possible in inversion mode.
ON mode
The ON mode (switch in position 3) is used to connect the module to NA contacts and to generate the
ON command only. For example, by connecting one input to the contact (NA) of a gas sensor, it is
possible to:
• in combination with a 3A or 16A output module, configured for BISTABLE operation, command
the closing of an NA solenoid valve after the sensor has cut in.
For example, by connecting the second input to a button (NA), it is possible to:
• in combination with a 3A or 16A output module, configured for TIMED operation, for managing
staircase lights, for example, to switch on the lights (ON) by pressing the button. The lights are
switched off (OFF) automatically when the time set on the actuator has elapsed.
Combinations with motor control actuators (e.g. for raising a roller blind when the channel is closed)
are possible in ON mode.
OFF mode
The OFF mode (switch in position 4) is used to connect the module to NA contacts and to generate
the OFF command only. For example, by connecting one input to the contact (NA) of a water sensor,
it is possible to:
• in combination with a 3A or 16A output module, configured for BISTABLE operation, command
the opening of an NC solenoid valve after the sensor has cut in.
Combinations with motor control actuators (e.g. for lowering a roller blind when the channel is closed)
are possible in OFF mode.

A blink of the green LED signals that a command has been transmitted.
INST LL TION
______________________________________________
The conventional input modules have inset installation, using the special System series supports.
The protection level can be maintained, even for installations other than inset (e.g. in junction boxes,
inside devices, etc.) by using the terminal cover.
Attention: the conductors of the two input channels are live when the output module is
powered up.
