2 DESCRIPTION
The LPC-2.IR2V is a sensor which consists of the lux sensor for light intensity measurements,
temperature sensor, relative humidity sensor and IR receive/transmit for IR communication.
Measuring light intensity, temperature and relative humidity provides the information needed for
achieving good work conditions. IR transmit feature can be used for remote controller substitution,
for example air conditioning can be controlled from Smarteh main module via LPC-2.IR2V in parallel
with remote controller. On the other hand, IR receive feature can be used for receiving commands
to the main module from Smarteh remote controller, smartphone or other remote controller.
LPC-2.IR2V is controlled and powered from the main module (e.g., LPC-2.MC8, LPC-2.MC9) via
Smarteh bus.

4 OPERATION
LPC-2.IR2V can be in one of two operational modes - normal or error. When LPC-2.IR2V is in normal
mode, module parameters can be read or written via Smarteh IDE software.
4.1 Operational modes
Normal
Communication with the main module is working. Only green “PWR” LED2 is turned on.
Error
In case of communication fault, red “ERR” LED1 will turn on.
4.2 Parameters
If parameter is set to logical “1”, is considered to be active, enabled or set. If parameter has logical
value “0” is considered to be inactive, disabled or cleared.
Parameter can be a command or feedback. When parameter is marked as feedback it means that
LPC-2.IR2V is sending information to the main module. On the other hand, command represents
request from the main module to the LPC-2.IR2V.

Type: WORD
If oIrProtocolSel
is "0":
When LPC-2.IR2V receives an IR command, value of iIrCmdRecNum corresponds to
the number of the IR learned command. Value is set back to 0 after next
communication cycle with main module or after approximately two seconds
regardless communication.
Raw to engineering data: 1 .. 15 IR receive learned command 1 .. IR receive →
learned command 15

Longo programmable controller LPC-2.IR2V
is "1":
When LPC-2.IR2V receives an IR command, value of iIrCmdRecNum corresponds to
the number described below in binary code which includes toggle bit, address code
and data code of the RC-5 protocol. When button is released, value gets to 0 after
next communication cycle with main module or after approximately two seconds
regardless communication.
Raw to engineering data:
In case that oIrProtocolSel is set to 2 .. 6, variable iIrCmdRecNum is not applicable,
because protocols are transmit only.

4.3 IR learn, receive and transmit
LPC-2.IR2V module can be learned to recognize 15 different IR commands. Module enters IR learning
mode as soon as the left pair of DIP switches (S1) are not in position for "No learning - receive only" –
see table 4.
IR learn is demonstrated on the example on how to learn LPC-2.IR2V the IR command "power ON"
from third-party IR remote controller for air conditioning and store it under command 15 in the LPC-
2.IR2V internal memory. IR receive and transmit is demonstrated on the example how to verify
stored IR commands.
IR learn
Set the S1 DIP switches to the setting than corresponds to the number under which IR command will
be stored. In this example, switches must be set to setting "learning mode for command 15". Once
this is done, LPC-2.IR2V is ready to receive the IR command from the remote controller and store it
to internal memory under command 15.
Press the button on the IR remote controller which you want it to be stored under command that is
set with DIP switches on LPC-2.IR2V. In this example, press "power ON" button on the IR remote
controller. Once the button has been pressed, the LPC-2.IR2V stores the IR command to internal
memory, in this example under command 15. LPC-2.IR2V will not store any other command under
command 15, unless S1 DIP switches has been changed to other setting and back to the setting
"learning mode for command 15".
IR receive
Which protocol should be used for IR receive, user can select with IrProtocolSel parameter. To check
if the IR command has been learned and stored correctly IrProtocolSel parameter must be "0".
Set the DIP switches to the setting "No learning - receive only" and than press button "power ON" on
the IR remote controller. If the received IR command corresponds to any of the IR commands stored
in the LPC-2.IR2V internal memory, the command number under which the received IR command has
been stored will be shown in the feedback parameter iIrCmdRecNum. In this example, number 15
should be shown.
If IrProtocolSel is set to "0" and DIP switches to the setting "No learning - receive only" than LPC-
2.IR2V will receive learned IR commands only.
If IrProtocolSel is set to "1" and DIP switches to the setting "No learning - receive only" than LPC-
2.IR2V will receive RC-5 IR protocol only.
Be advised that during IR transmit, IR receive is blocked.
IR transmit
In order to check if the IR command that was stored can also be transmitted correctly, the LPC-
2.IR2V should be used as a substitution of the IR remote controller. On the main module, number 15
should be written to the LPC-2.IR2V command oIrCmdSendNum. This command selects IR command
which is stored under number 15 for transmit. IR transmit is executed once oIrCmdSend is set to
logical “1”. In this example, air conditioning should be turned ON.
Procedure for IR learn can be repeated for 15 different IR commands. DIP switch setting corresponds
to learning mode for one of 15 commands and IR receive only mode – see table 4.
The IR commands may also be learned during manufacturing process - consult with Smarteh.

5.2 Mounting frame selection
Frame, suitable for IR2V module insertion, should be modular one at least 1 gang wide. Be careful to
have corresponding flush-mounting box provided on the place where module will be positioned.
Smarteh has verified following lines to be compatible with LPC-2.IR2V module:
● Bticino – Living, Light
● Gewiss – Playbus, System
● Vimar – Plana, Idea
● Tem
● Master
Frames of other vendors most probably suits as well, but they were not verified by Smarteh. Before
installation verify compatibility of non listed frames.
Module housing has a fin on each side, which can be easily removed with knife cutter or pliers. This
adaptation enables housing to be inserted in various frame formats. With regard to frame used you
may remove fin for housing to fit in.

5.3 Mounting instructions
Figure 4: Housing dimensions
Dimensions in millimetres.
All connections, module attachments and assembling must be done
while module is not connected to the main power supply.
Module should be positioned in the wall inside of the room. Avoid
direct sunlight, positioning near heating/cooling source object or
under high luminance lights for best performance of the on-board
sensors. Junction box and tubes in the wall must be sealed to prevent
airflow. Displayed temperature is adequate to temperature approx. 10
cm below module and 1 cm off the wall. Recommended installation
height is 1.5 m above floor level.
Mounting instructions:
1. Set the correct RS-485 address (S2 switch) for LPC-2.IR2V (table 5).
2. Connect interconnection cable to the connector K1. Max. allowed tensile force is 30 N.
3. Put the LPC-2.IR2V in mounting frames, with ventilation slots positioning downwards.
4. Cover LPC-2.IR2V with cover plate.
LPC-2.IR2V is connected to main module with interconnection cable (e.g. SSK, ICM-7) which must be
ordered together with LPC-2.IR2V. When more modules (e.g. LPC-2.CR1, LPC-2. CH1, LPC-2.DP1,..)
are connected to main module, splitter (e.g. SPL-2) is required (figure figure 2).
NOTE: Signal wires must be installed separately from power and high voltage wires in accordance
with general industry electrical installation standard.
