DESCRIPTION
LPC-2.DP1 control panel (CP) is used for room temperature regulation for systems with Fan speed
control (Fan-coil...)..
Panel is equipped with temperature and light intensity sensor and four touch buttons (TB).
To increase, decrease temperature set point warmer, cooler TB should be pressed respectively.
Temperature SP is represented with right LCD bar-graph. While CP is in heating mode (temperature
SP is higher than actual room temperature), LCD SP bar is red and while in cooling mode
(temperature SP is lower than actual room temperature), LCD SP bar is blue. If actual temperature
is in SP +/- Dead band range, LCD SP bar is white.
With fan TB speed I, speed II, speed III, AUTO or OFF modes of operation can be selected.
Fan mode is represented with left blue LCD bar-graph.
With ECO (economy), OFF and ERR (error) signs on LCD, CP status is represented.
Color back ground LCD picture is possible to change by using Smarteh LCD Composer software.
Light intensity sensor controls LCD intensity.
It is possible to display actual temperature value (0.5 °C resolution) and temperature set point. The
real time clock ( :MM) can also be displayed. Enabling can be done by main module enable
commands.
All parameters are accessible on panel's communication port. When panel is connected to the LPC-2
main module parameters can be viewed and modified with LPC Manager application.
LPC-2.DP1 parameters and functions allows adaptation to desired system and regulation diagram.
Panel is able to regulate 2 or 4-pipe systems, depending on 4/2 pipe parameter.

3 OPERATION
Basic setting can be entered with panel Touch Buttons (TB).
Modes of operation and parameters can be set via LPC Manager software, some of them can be also
activated through special sequence TB pressing.
It is advised to press touch-buttons respectively with finger not faster than 1 press per second.
Press should be done with whole finger tip. Brief pressing could not activate the action, because of
protection against the noise and other influence.
3. Operational modes
LCD Display “stand-by mode”
The display is normally in this mode, if no TB is pressed in last ~5 seconds.
LED intensity is in correlation with Light intensity measurement (more light - brighter, less light -
darker).
Actual room temperature (0.5 °C resolution) is shown on the screen if enabled.
LCD Display “SET mode”
First press on any TB will activate the display to “set mode” and LCD intensity will be put to
maximum. No action regarding the pressed TB is done. Further pressings on any TB will make the
change(bar-graphs) regarding the pressed TB.
Actual temperature set-point (regarding the right bar-graph) is shown on the screen if enabled.
Display will return to “stand-by mode” if touch buttons are not pressed for a while (~5 seconds).
Changing operation modes
Request for switching between CP normal and economic operating mode is done with lower left and
right TB pressed simultaneously :
switch to economic mode
Request for switching between CP on and off operating mode is done with upper left and right TB
pressed simultaneously :
CP switched off
Confirmation of above requested modes is done by main module by changing the appropriate
command bit (normal/economic, system on/off).
Normal
This is default mode for DP1 module. The control algorithm is executing regarding the parameters.
Economy
If set, controller will start cooling when room temperature will raise above max. temperature set-
point (SP) and stop when temperature will drop 1 °C below max. temp. SP. On the other hand, when
room temperature fall's below min. temp. SP controller will start heating and stop when
temperature will raise 1 °C above min. temp. SP.
In economic mode “ECO” sign appear on LCD.
Off
In this mode panel sends command to switch off all devices: hot valve, cold valve, fan. Temperature
LCD bar becomes white and “OFF” sign appear on LCD.
CP can be turned off using fan TB or System On/Off command. In this case cool, heat and fan
commands are switched off. Cool and heat commands are also switched off when temperature

Longo programmable controller LPC-2.DP1
measured by the panel is inside temperature dead band values (default dead band is 0.5 °C).
Error
In case of CP internal on communication fault, “ERR” sign appear on LCD.
Set
When any of four buttons is pressed more than certain time, “SET” sign appear on LCD and buttons
functioning is enabled. After “SET” sign is off, push buttons functions are disabled.
3.2 Functions
PI controller
Output variable range is 0 to 10000 (0..100%) in heating and/or cooling mode respectively .
Values are used for analog/digital (0..100% / I.,II.,III. speed ) output reference for the fan speed
and/or the output for the heat/cool actuator (0..100% / On-Off valve).
The dynamics of PI calculation is defined by P& I parameters.
Example:
If proportional – P parameter (default = 25) is set to 1 and difference between measured
temperature and temperature set point is changed to +1 °C, the PI output value will change from
example 5000 to 5100. On the other hand if the difference is changed to -1 °C, PI output value will
change from example 5000 to 4900.
If integral – I parameter (default = 5) is set to 1 and difference between measured temperature and
temperature set point is +1 °C, the PI output value will increase every second by 1. On the other
hand if the difference is -1 °C, the PI output value will decrease every second by 1.
2/4 pipe system selection
While 4-pipe (factory default) system active, controller will activate hot water actuator when
heating is required and cool water actuator when cooling is required.
In case 2-pipe system is active, hot water actuator will be operated regardless whether heating or
cooling is needed. Mode of operation (closing, opening) is dependent on Winter/Summer parameter.
Example:
System selected is 2-pipe , summer mode active and SP is lower than room temperature. CP will
start cooling with activating heat valve. In 2-pipe system cool valve is always inactive.
Frost protection
Function activates heat command when room temperature measured by the panel drops below 7 °C.
This function has priority over all control panel integrated functions.
Window open
Panel will operate in special mode if opened window and opened balcony door are detected. This
function is enabled by enabling parameters Balcony door En. or Window En. When this function is
active and one of parameters Window or Balcony Door commands is active, fan will stop and valves
for heating and cooling will close (delay of 1 minute is add with Balcony door command).

3.3 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 status, command or both. When parameter is marked as status this means that
module is sending information to controller. On the other hand, command represents request from
main module to module.
Communication: Normal state is “1”. If off, there is communication error or no communication
established.
Normal/Economic: When set Economic mode is enabled. Default value is “0” therefore normal mode
is selected.
Local/Remote: When “0”, Local mode is selected. In this mode CP uses set point set by TB.
In remote mode, “1”, CP uses set point received from other devices ( MI, Touch Panel, OT1,
..) through communication channel.
Heat valve: When valve is opened “1” is reported, while “0” stands for closed valve
Cool valve: When valve is opened “1” is reported, while “0” stands for closed valve
System On/Off: If parameter is set to “0” CP functions are executing in normal mode. If set to “1”
Fan speed and all valves are OFF (closed).
Winter/Summer: Used only for two-pipe system to change calculation for ot valve and Fan speed;
Winter – heating (“0”) to Summer – cooling (“1”)
4/2 pipe: Four-pipe system manages hot and cold water pipes simultaneously. Two-pipe system
manages only one pair of pipes (one valve, pump). Operation in two-pipe system is therefore
dependent on Winter/Summer (Change-over) parameter.
“0” = Four pipe system
“1” = Two pipe system
Fan speed I.: When this parameter is “1”, actual fan speed is I.
Fan speed II.: When this parameter is “1”, actual fan speed is II.
Fan speed III.: When this parameter is “1”, actual fan speed is III.
Fan speed mode : This parameter determines fan speed adjustment mode:
“0”: Manual
“1”: Auto
Balcony door En.: When switch for detecting opened balcony door is connected to the system, this
function should be enabled (“1”).
Balcony door switch: Parameter reports whether door are closed or opened
“1”: closed
“0”: opened
Window En.: When switch for detecting opened window is connected to the system, this function
should be enabled (“1”).
Window switch: Parameter reports whether window is closed or opened
“1”: closed
“0”: opened
Max. temp.: denotes max. SP temp. which is scaled to top of LCD temperature bar
Min. temp.: denotes min. SP temp. which is scaled to bottom of LCD temperature bar
P regulation par.: Proportional parameter for PI calculation algorithm on CP
5

Longo programmable controller LPC-2.DP1
I regulation par.: Integral parameter for PI calculation algorithm on CP
PI Dead band: Value of change for PI loop output.
Fan reference: denotes fan speed value requested by panel
Temp. SP: This value is taken into PI calculation algorithm
Room temp.: Room temperature measured by CP panel.
Auxiliary room temp.: Room temperature value from other sensor is taken into PI calculation as
room temperature instead of temp. value measured by CP panel.
Absolute PI out: Result of PI calculation algorithm used for fan speed and valve opening
Light intensity: Actual light intensity measured by sensor on CP
Min. light intensity: When Light intensity is lower than this parameter, LCD bar graph on CP turns
off
Remote temp. SP: When Local/Remote parameter is active this parameter is taken into PI
calculation algorithm as SP.
Fan mode set: Fan mode on CP panel can be remotely changed by main module.
[0,1,2,3,4=Off,I.,II.,III.,auto]. The change is made by setting the Fan Remote Cmd. command
bit.
Remote Fan mode inc: When this command changes to active, Fan mode on CP panel will be changed
in increment-rotate way [->Off,I.,II.,III.,auto,->].
SP up: When this command changes to active, CP will increment SP for 1/10 of scale. It acts like
pressing on Warmer TB on CP.
SP down: When this command changes to active, CP will decrement SP for 1/10 of SP range. It acts
like pressing on Cooler TB on CP.
Real Time clock: Real time clock ( :MM) value by main module for display on CP panel. Displaying
is enabled with RTC Enable command bit.
Fan DB Off: If this command is active, the Fan speed inside dead-band goes to Off. Otherwise it
remains in low speed.
Temp. display Enable: If this command is active, displaying of actual Room temperature on the CP
panel is enabled.
TB pressed: This parameter indicates that any of TB is pressed.
