Supervision and control
1.1
The program
This air handling unit is managed by its controller. In addition to its control functions, it also monitors and detects any faults with the
air handling unit.
The HMI terminal displays the following data which can be edited at any time:
. values of connected sensors
. unit on/off cycles
. calibration of the sensors
. detection of alarms and log of the last 100
. the password-protected configuration and operating parameters
. device running times and time delays
. management of time programs (4 daily, 4 weekly and 4 yearly programs)
. language selection (French)
The connection with the pLAN network allows the program to use a terminal mounted on the front of the AHU and/or a wallmounted terminal installed in the room to be air conditioned.
IMPORTANT: To avoid any problems, the password must be known only by qualified personnel.
1.2
The HMI terminal
The terminal provided is equipped with a remote LCD display (8 lines x 22 columns) on the outside of the unit, which has 6 keys
(connected with a phone cable, max length 50m). It allows all of the program operations to be carried out. The terminal displays the
unit's operating conditions at any point in time and allows the parameters to be modified; in addition, it can be disconnected from
the main board as its presence is not strictly required.

24VAC
The room terminal and the controller are electrically connected using an AWG20/22 shielded cable (not supplied by CIAT)
comprising two twisted pairs.
The first and last controller must be no more than 500m apart. This network must never run parallel to power cables at a distance
of less than 50 cm. These cables may cross, but perpendicularly. You are requested not to form a loop with the network cable or
the earth braid, and to properly separate the various cable families (control, power, earth and communication bus).
In case of transmission problems, it is vital to connect a 120Ω ¼W electrical resistor between terminals TX+ and TX- of the room
terminal, as indicated in the manual supplied with the room terminal.

Starting up and switching off will take place locally by pressing on the  and  keys on the display.
Remote control is available and carried out by a potential-free contact between terminals 1 and 2 in place of the factory-installed
shunt.
The unit is to be switched on/off by the CMS.
The unit will start up if the 3 running orders are actuated (on the display, on the remote control and via the CMS, depending on the
configuration).
If one of the 3 orders is in "Off" mode, the unit will be stopped.
1.6.2
Safety and insulating damper
The insulating damper is activated by an On/Off servomotor with spring-return.
When the unit is stopped, this damper is normally closed.
When unit start-up is requested, it will open and the controller will wait whilst the servomotor opens, then the unit will be switched
to "On" and the damper held open unit the next request to stop the unit or, if a safety damper is being used, for the appearance of
the antifreeze protection alarm.
SMR
1.6.3
Antifreeze thermostat
The antifreeze thermostat has a manual reset and it is constantly monitored once the controller is switched on.
If an antifreeze alarm is activated, the fresh air damper is closed, the valves on the hot water coil installed in the air handling unit
are opened fully and the fault is signalled.
A frost prevention function is available once the unit is switched off. This consists of leaving the hot water coil valves slightly open
(adjustable value) to maintain pre-heating.
1.6.4
Fire fault
The fire fault contact (option) connected to a PLC input is used to signal the appearance of the fire fault and disables the fans.
12
1.6.5
Fan motors
The motor or motors start when the unit is in "On" mode.
The alarm feedback from the motor(s) is used to check their electronic switching protection. If one or other of these signals is not
received, the unit is stopped and the faults are signalled.
Their rotation speed is controlled using one of the 2 following modes:
1.
to maintain the fans at a constant flow ("Flow rate") in accordance with the setpoint(s) on page w0, based on the
configuration on page p3 of the "Adjustment parameters" menu and the air quality setpoint (option) until the
maximum flow rate limit on page w3 is reached.
2.
to maintain a constant pressure in the supply air duct ("Pressure") in accordance with the setpoint on page w1 and
based on the configuration on page p3 of the "Adjustment parameters" menu.

Filtration
3 different filters can be monitored simultaneously: 1 in the Supply air flow, 1 in the Return air flow and 1 additional filter in either of
the 2 flows.
To check their fouling level, each filter is equipped with a differential pressure sensor which measures its upstream/downstream
pressure drop. This sensor has a measuring range of 0-1250 Pa. In addition to monitoring the fouling level, this sensor also checks
for the presence of an air flow crossing the filter, and therefore the unit, in both directions (Supply and return air). This information
is required for activating the regulation.
For the additional filter, its pressure drop is checked by a pressure switch which will provide information on the saturation level
reached in the controller via a contact.

Temperature control
The regulated temperature may be:
the return air temperature
the room temperature
the supply air temperature
Two temperature control schemes are available:
"Precision" mode, where a low deviation from the reference temperature is requested.
"Energy optimisation" mode, where the key factor is the cost of energy.
"Precision" mode:
In this case, the regulated temperature is the room or return air temperature and the difference between this temperature and the
setpoint enables the setpoint used as the basis for controlling the supply air temperature to be calculated.

 When the temperature drops, the controller will calculate the heat requirement needed to keep this temperature constant.
This gradually adjusts the output of the 2 heating coils (via a 3-way valve for coil 1, via a triac or using 1 or 2 stages in the
case of an electric heater) or a "Mixed" type in heating mode (authorised by the water network temperature sensor for coil 2

Plate recovery
A differential pressure switch is used to check the fouling level on the return side of the heat recovery unit and to manage the frost
protection safety function when the unit is running. This safety function activates the bypass damper.
This damper is also activated if there is a Free cooling request.
1.6.9
Electric heater
In case of a problem on the electric heater (safety thermostats), the electric heater is shut off and the fault is signalled.
Load shedding of the electric heater via the input ID6 is available (function also available through communication with the CMS).

Free cooling
The aim of this function is to make use of fresh outdoor air before starting to use the cooling coil to cool the building's supply air.
This function is only available if there is a mixing box or a plate heat exchanger equipped with a bypass damper.
Free Cooling management is based on actuating the mixing damper servomotor to alter the proportion of fresh air brought into the
building and opening the plate heat exchanger bypass, if present.
To authorise Free cooling, certain conditions must be fulfilled:
The fresh air temperature must be below 17°C.
The fresh air temperature must be below the return (or ambient) air temperature – 3°K
If there is a mixing damper, the percentage of fresh air depends on the cooling request sent by the regulation. A minimum value of
fresh air supply when the unit is stopped is adjustable.
SMR
1.6.11
Humidifier
Humidification of the intake air is managed via a self-contained humidifier equipped with a humidity sensor and authorised to
operate in accordance with the order given by the controller once the unit is running at optimum levels.
A summary of faults will be sent back to the controller via a potential-free (dry) contact so an alarm is displayed.
1.6.12
CO2 air quality
The aim is to regulate the air quality, measured in ppm of CO2, using a duct sensor measuring the return flow, the measurement
range for which is 0 to 2000ppm.
There are two possible actions to manage the air quality, which can be combined:
Either the mixing damper is managed to alter the proportion of fresh air supplied to the building
Or the fan flow rate is varied
In the event that the two actions are selected, the controller will actuate the mixing damper, then alter the fan flow rate.
This management is incompatible with pressure regulation in the supply air duct.

Night cooling
The aim of this function is to use the coolness of fresh air from outdoors during the night within the building, with an option of overventilation, as far as the system will allow.
This function is only available if there is a mixing box or a plate heat exchanger equipped with a bypass damper.
It is activated by a timer or the CMS, whilst the room air or return air temperature is checked against a setpoint.

incorrect connections or a wrong address. The state of the pLAN network can be displayed in real time on this special mask in
order to identify which devices (controller or terminal) are correctly connected and addressed.
Network addresses 1 to 32 are displayed. The small rectangles
represent the terminals and the large rectangles , the
controllers.
If the symbols flash, the pLAN may be unstable or, more likely, two components share the same address.
The example indicates that the network is formed of 1 controller with the address 1 and 1 terminal with the address 17.

Managing a network of controllers
The pLAN network is the name of the physical network that links controllers to remote HMI terminals.
pLAN = personal Local Area Network
The connection of the controllers via the pLAN network allows the datapoints of one controller to be exchanged for another,
following the logic set out by the program, i.e. the direction that these datapoints must follow and that from which they come. As a
consequence, they are not programmed by the user, who must only carry out the electrical connection.
3.1
pLAN electrical connections
Connecting controllers to the pLAN
The electrical connection between the controllers under the pLAN network (RS485) is carried out using an AWG20/22 shielded
cable composed of a twisted pair and a shield. The cards must be connected in parallel using the J11 connector.
The first and last controller must be no more than 500m apart.
3.1.1
40
3.1.2
Connecting a remote screen to the pLAN
A remote user terminal can be connected to each controller on the pLAN network (RS485) using two cards (CIAT code: 7122917)
and one shielded cable consisting of three AWG24 twisted pairs and a shield.
The shielded cable must be no longer than 200m.
41
3.2
Addressing the pLAN
Once the controllers are connected over the pLAN network, the controllers and the terminals must be addressed.
There is a range of 32 possible addresses (binary logic). As a result, a total of 32 controllers and terminals can be connected over
the pLAN network.
The pLAN network will not work if the same address is shared by two components!
The controllers and displays must be addressed as illustrated below:

3.3
Changing the controller address
The controller pLAN address can be changed, when creating a rotation loop, in page pL1 of the Parameters menu, following the
diagram shown above.
3.3.1
Addressing the HMI terminals
The value of the factory-set address is '17'.
In order to be able to configure the terminal's address, it must first be powered via the telephone connector.
To enter configuration mode, press and buttons   and  (even if the terminal is already on) simultaneously for at least five
seconds. The mask of the screen below appears and the pointer flashes at the top left corner:
• to change the terminal's address (display address setting) press the  button once. The pointer will move to the address field
(02).
42
• select the desired value using the   buttons and confirm by pressing the  button. If the value selected is different from that
previously stored in memory, the mask of the screen below will appear and the new value will be stored in the display's permanent
memory.
If the nn field is set to '0', the terminal will use the Point-to-Point Protocol (not the pLAN) to communicate with the controller and the
“I/O Board address: 07” field will disappear as it will not be necessary.
3.3.2
Assigning private and shared terminals
Follow the procedure below if, at this point, it is necessary to change the list of terminals associated with each controller:
• enter configuration mode by pressing the   and  buttons as described in the previous section;
• press enter until the pointer moves to the "I/O board address" field;
• using the   buttons, select the address of the desired controller. The only values selectable will be those of the controllers that
are on the network. If the pLAN network is not working correctly or if no controllers are present, the field cannot be changed and
will display a “—”;
• press the enter button once more. the following mask sequences will be displayed:

• as above, press enter to move the pointer from field to field. Press the   buttons to change the value of the current field. The
P:xx field shows the address of the selected controller. In the example above, controller No. 07 is selected;
• to exit the configuration procedure and store the data, select "YES" in response to “OK?” and confirm with the  button.
In the case of a shared display for a set of units (maximum 31), the terminal must be configured on each unit in "Sh" mode.
The fields in the “Adr” column contain the addresses of the terminals associated with the controller whose address is 07; the
“Priv/Shared” column shows the terminal type.
Warning: HMI terminals do not have a printer output and therefore cannot be configured as “Sp” (shared printer).
If the terminal remains inactive (no buttons pressed) for more than 30 seconds, it will automatically exit configuration mode without
saving any changes made.
43
3.3.3
Checking the pLAN address
The pLAN address is displayed in the top left of the main screen, the pLAN NETWORK pL1 screen in the "Communication" menu
and the Program pr1 screen of the "Versions" menu.
3.4
State of the pLAN
When the system starts up, the pLAN network may encounter a number of problems (card fault and terminal start-up) caused by
incorrect connections or a wrong address. The state of the pLAN network can be displayed in real time on a special mask in order
to identify which devices (controller or terminal) are correctly connected and addressed.
To display this special page, simultaneously press   and  on any other terminal on the network for at least 10 seconds. After
the first 5 seconds, a page is displayed; after 5 more seconds, the next page appears:
NetSTAT
Term : 17
Press Enter to quit
Once on the screen, network addresses 1 to 32 are displayed. The small rectangles represent the terminals and the large
rectangles , the controllers. If symbols appear then disappear, the pLAN may be unstable or, more likely, two components share
the same address. The number after Term indicates the address of the terminal used. The example shows that the network is
made up of 3 controllers with the addresses 1, 2, 25 and 4 terminals with the addresses 3, 4, 15 and 26. Once the page has been
verified, turn off the power, check the connections and addresses, then turn the power back on.
4
Replacing the lithium battery
The lithium battery must be replaced by the customer when the notification alarm appears, approximately 10 years after the unit is
commissioned on site.
Once the replacement has been carried out, do not forget to reset the battery check (mask tp1)
5
Supervision
The controller may be connected to a local or remote supervision PC or to most types of CMS (Modbus, Lonworks, KNX). For the
listed functions to be used, optional cards (Rs485, KNX, LON) or gateways (devices able to interpret various communication
protocols) must be installed
NOTE:
If using a communication bus, the routing and processing of the available data are outside CIAT's scope of supply. They must be
provided by the installer, and require the involvement of an integrator.

The components required for connection to the remote and/or local ModBus supervision system are as follows:
An RS485 serial card (CIAT code: 7119749) connected to each controller.
A standard RS485/USB converter for connection to a PC (not supplied by CIAT). The converter can be connected to any
network RS485 card.
An electrical network using an AWG20/22 shielded cable (not supplied by CIAT) comprising a twisted pair and shielding
with a max length of 1000 m. This network must never run parallel to power cables at a distance of less than 50 cm.
These cables may cross, but perpendicularly. You are requested not to form a loop with the network cable or the earth
braid, and to properly separate the various cable families (control, power, earth and communication bus).
A supervision program installed on a PC (not supplied by CIAT).
An 120Ω ¼W electrical resistor must be connected to the RS485 serial card in last position on the bus, as shown in the connection
diagram.
The format of the data frame, which cannot be modified, is as follows: 8 data bits, 2 stop bits and without parity on 2 words (2
bytes), high-order, low-order.
The data format (16 bits, signed) is standard for Modbus except for analogue data which is in the format "Integer divided by 10"
45
The codes for the Modbus functions used are:
1 or 2: Read n bits
3 or 4: Read multiple registers (16 bits)
5: Write one bit
6: Write one register
8: Read diagnostics counters
11: Read event counter
15: Write n bits
16: Write multiple registers (16 bits)
NB: The JBus addresses are equal to the "Modbus address" - 1
5.3.3

Configuration process
The diagram below illustrates the phases of the "configuration process" required for configuring the card correctly:
XML file
No group
addresses
kSET:
Enter the group
addresses
ETS3 project
XML file
complete

Assign the addresses
to all the modules, and
configure products
other than CAREL
ETS3
Create the links
between the various
datapoints, i.e.,
allocate the group
addresses
.pr4 file
with the
CAREL Plugin
XML file
Download XML file to
the CAREL modules
(table with group
addresses)
ON-line:
Download the configuration
Physical connection to

It is important to remember that the same group address cannot be assigned to more than one Datapoint.
5.5.4
CAREL plugin
As is the case for other manufacturers' devices, the ETS3 data archives must be loaded with a specific description of the device.
CAREL distributes a plugin in the form of a "project database", which assigns the addresses and downloads the table created by
K-Set, i.e., the XML file.
5.5.5
Installing the plugin
The plugin is installed as follows:
. Find the file "Carel_plugin_21.pr4" (the updated version of the plugin is available from ksa.carel.com)
. Import "Carel_plugin_21.pr4" using Files → Import as shown below:
62
. Select Import all
. Using Files → "Open/Manage projects…", open the project named Carel_plugin_V2.1 (or above):
. Open the project using Open, select the device "CAREL Plugin", right-click on the mouse and select Copy:
63
. Open or create the final project for the system and right-click on the mouse to paste the CAREL plugin, once or more
according to the number of CAREL devices to be integrated. The address of each device is automatically incremented. If
necessary, you can manually change the address of a device in Properties.
5.5.6
Assigning the physical address
The physical address of the CAREL KNX card is assigned using the standard procedure.
You must be sure that:
. the Bus wire network is drawn out and connected
. the Bus is energised
. the CAREL card is connected to the KNX network
. the controller is powered on
Use the mouse to select the controller to be configured, right-click to open the "Download" menu, Fig.7.d and Fig.7.e.
Select "Program Individual Address" to activate the configuration procedure and press the button on the card. The green LED on
the card goes out to indicate when the operation is complete. If the card address has already been configured, the message "The
address is already used by another device" is displayed.
64
5.5.7
Downloading the XML file
You must be sure that:
. the Bus wire network is drawn out and connected
. the Bus is energised
. the CAREL card is connected to the KNX network
. the controller is powered on
Use the mouse to select the controller to be configured, right-click to open the "Properties" menu; scroll down the list using the
arrows at the top right until the label "CAREL device configuration" is displayed.
Use "Choose XML file" to open the XML configuration file required.
Click on "Download data" and wait for the "Success" message to be displayed. During this phase indicated by the "Performing
operation" message and the LED on the card flashing green, no other operation may be performed. The download time may vary
according to the size of the XML file and the network traffic; for a maximum size file, this time may be 2 minutes.
In extreme cases, i.e. high traffic and large XML files, the bus may be disconnected and ETS3 will signal an error. In this case,
simply repeat the download.
NB: This procedure is specific for the CAREL card, and is the sole configuration operation permitted by the ETS3 program, in
addition to allocating the address.
