To modify the installation parameters, a display terminal is essential (wall-mounted display terminal, ush-mounted display terminal
or radio remote control terminal).
To enter set-up mode, you need to simultaneously press the standby , ventilation and buttons for 5 seconds, then press
the button twice, and finally the standby button for 5 seconds.
The parameter is selected by pressing the and . buttons. To consult a parameter value, you need to press the standby
button . To validate a parameter modification, press the standby button. To exit set-up mode, press the ventilation button .
If a set-up has been changed and you go back to normal operating mode, the terminal display switches off briefly and then
displays its version number (e.g. 101) for around 5 seconds, while it reconfigures the controller before going back to the normal
display.

Certain problems may be resolved by checking some fundamental points. Check using the list below before requesting servicing.
N.B.:
When the controller is switched on, control will only take effect after a few minutes of system initialisation.
If you have a display terminal, this displays its version number (e.g. 101) for around 5 seconds after switching on.
Upon a mains power cut:
1. when power is restored, the controller restarts automatically in the mode operating before the cut, with:
if Comfort Mode, it restarts in Comfort mode, but it is not store:
- The setpoint override returns to the middle point
- The ventilation speed returns to Auto
2. All information from the KNX bus is lost.
3. Error message: diagnostic d23 saves the last error message. d23 is saved even in case of a power cut.

●Parameter P24
Diagnostics d08, d09
The V3000 offers the possibility of controlling the air temperature via a return sensor or an indoor environment sensor (P24).
If you can choose between the two, it is preferable to opt for the indoor environment sensor, since it provides a better picture of
the room temperature.
The indoor environment sensor is situated inside the user terminal unit. When it is used, particular care must be taken in choosing
the location of the user terminal in the room (do not expose it to sunlight, or place it on top of a device giving off heat - put it on
an inside partition).
The end of the wiring conduit must be heat insulated.
20 cm
mini
150 cm
~ 150 cm
The choice of sensor is made using parameter P24 (=0: return sensor; =1: indoor environment sensor).
If the selected sensor is faulty, the other sensor immediately takes over. A symbol is displayed on the screen and the fault can
also be looked up in the variable of diagnostic d22.
In case of doubt about the origin of the displayed temperature value, the value measured by the return sensor can be read in d09.
The value measured by the indoor environment sensor can be read in d08. If the sensor is absent, the value displayed is equal to 0.0°C.
The sensor measurement can be corrected by means of parameter P25 (return sensor) or P26 (indoor environment sensor).
6 - AIR TEMPERATURE MEASUREMENT
●Parameters P27, P28
Diagnostic d11, d12
The 2-pipe hot/cold fan-coil units may be tted with a water temperature sensor (or changeover sensor). It must be positioned
using a conduit clip by the installer upline of the four-way valve (water piping end). It is fastened to the pipe by means of
electrician's clamps.

Sensor
●Changeover operating algorithm:
- If the changeover sensor measures water temperature greater than 7°C (adjustable in P27) at ambient temperature, the
water is deemed to be hot.
- If the changeover sensor measures water temperature less than 4°C (adjustable in P28) at ambient temperature, the water
is deemed to be cold.
- If the changeover sensor measures water temperature between these 2 values, the water is deemed neutral.
●Changeover operation with water at neutral temperature:
In this scenario, and when there is an established need from the controller, the V3000 launches a test cycle on the valve every 45
mins so as to check the network's available water temperature (valve 100 % opened to authorise water circulation in the terminal
unit coil).
- If this temperature does not vary, the V3000 keeps the same status
- If this temperature varies and returns to the conditions described above, the V3000 re-authorises its control cycle
Important : the changeover sensor measures the surface temperature of the piping. There is an obvious difference between the
actual water temperature and the surface temperature. The water speed will therefore be selected so as to guarantee changeover
switching
.
- For P31 = 1, if nothing is connected between terminals S2 and C, the controller deduces that the water circulating in the coil is
still cold. If there is a bridge between these terminals, the controller deduces that the water is still hot.
- For P31 = 2, the controller waits to receive the water temperature from the central management unit before starting in heating or
cooling mode (if it does not receive a temperature value, it will not start its heating or cooling control sequence and will indicate
alarm E11)

Parameters P40, P41, P47, P48, P49, P50, P51, P52, P62, P67.
●PID setting
The Proportional Integral Derivative control parameters are set in the factory.
The values are:
- Hot Proportional Band: 4 K
- Hot Integration Time: 5 min
- Hot derivative time: 1 min
- Cold Proportional Band: 2 K
- Cold Integration Time: 10 min
- Cold derivative time: 1 min
These values, validated in the laboratory, enable “Comfort” operation in most terminal unit applications.
●Neutral zone ventilation
According to the operating mode, the neutral zone ventilation is set in the factory as follows:
- Comfort mode (P40): 0 Ventilation off (if controller with indoor environment sensor) or 3: periodic restarts (if control with
return sensor)
- Standby mode (P41): 0 Ventilation off
- Economy mode: 0 Ventilation off
- Frost protection mode: 0 Ventilation off
- Neutral zone ventilation is adjustable via P40 and P41, to comfort and standby mode
It is possible either to cut off the ventilation after 2 mins post-ventilation (parameter = 0), or have constant low speed ventilation
(parameter = 1), or have constant ventilation in the summer and cut off in the winter (parameter = 2), i.e. ventilation on every 30
mins for 30 seconds.
If control is applied using the return sensor, it is strongly recommended to have continuous low speed ventilation.
The setting of these parameters is derived from a compromise between control precision, physiological comfort and energy saving.
- When the V3000 is powered up, the deadband ventilation process will be effective as soon as the rst heating or cooling request
is made for a room.
●Minimum ventilation time
In automatic ventilation, the controller automatically engages the ventilation speeds. To limit the number of ventilation speed
changes, there is a stipulated minimum ventilation run time of 2 minutes at each speed.
●Comfort override delay
To control energy consumption, the controller may limit the operating time in comfort mode following a user override. This delay
is not applied when the order to enter comfort mode comes from the central management unit. Parameter P48 enables you to
set a timer between 30 mins and 24 h, or to prohibit any comfort override (P48 = 0). This function may be disabled (P48 = 24.5).
- If P48 = 24: the setpoint overrides are not stored upon return to standby mode. The current fan speed is not memorized and
returns to AUTO.
- If P48 = 24.5: the setpoint overrides are stored in all operating scenarios. The current fan speed is not memorized and returns
to AUTO.
●Operating mode activated by standby button
According to parameter P47, pressing the standby button switches between comfort and frost protection, or between comfort and
economy, or between comfort and standby.
In all cases, the central management unit maintains the option of selecting each of these operating modes.
●Electric heater operation limiting according to outdoor temperature
The controller can limit operation of the electric heater according to the outdoor temperature, once the comfort temperature has
been reached.
To do so, the base outdoor temperature must be defined (P62), the minimum temperature reachable at least 5 times in the course
of a normal winter.
The outdoor temperature information must come from the BMS via the KNX bus.
●Management of heat exchanger coils
Parameter P67 indicates to the controller whether it has at its disposal a hydraulic coil and electric heater, one of the hydraulic
coils only or an electric heater only.
Certain central management units modify this parameter to temporarily prohibit use of certain coils according to external events
(thermodynamic unit switched off, need to limit electrical energy consumption…).
To get a better understanding of what is going on, diagnostic d13 recalls the value of P67 and d12 indicates the current status
following any action by the central management unit. Depending on what is defined in P67 and what the central management
unit requests (see d12), the regulator determines whether it can have hydraulic coils and electric heaters.
Diagnostic d11:
- If the controller is working based on its changeover sensor wired to S2 and C, d11 indicates the temperature read by this sensor.
- If the controller is working based on an On-off contact wired to S2 and C, or based on information from the centralised changeover
- d11 indicates 127°C if D2/C is shunted or centralised changeover = hot water.
- d11 indicates -72°C if D2/C is not shunted or centralised changeover = cold water.
Diagnostic d12:
Certain central management units may temporarily prohibit heating or air conditioning operation.
Diagnostic d12 will tell you the current authorisations.
Frost protection is enabled even if no heating authorisation has been activated by the supervision.
Very important: the sensor should be placed on the water inlet pipe. It must be installed on the pipe before being insulated .

●Universal inputs
The V3000 controller is equipped with 2 congurable potential free inputs. These 2 inputs D1-C and D2-C are delivered from the
factory with a bridge. If you want to connect contacts to the inputs (frame contact for example), the bridges must be removed.
- Universal input D1

●Diagnostic d05, d06
The fresh air function can be carried out in various ways:
- Ambient temperature control with supply air series (all fresh air):
The room temperature measurement must be taken with the sensor of a terminal located in the room.
In Comfort mode, the controller applies PID room control with all fresh air; but if the supply air temperature drops below the supply
air setpoint (set via parameter P09) while the room control is in neutral zone or heating sequence, then the control switches to
supply air control cycle with a proportional algorithm.
In winter, this function prevents the cold shower effect, a source of discomfort, by supplying preheated fresh air even if no heat
gain is required in the room. In cooling mode, the supply air control is locked.
If the hot valve opens fully, or if the frost protection thermostat is triggered (given by P52 = 10), the valve closes and the fan is
switched off immediately.
If the unit has a display terminal, the "Fro" information is displayed when the Frost protection is triggered by the safety thermostat.
An adjustable spanner appears upon the "hot valve 100 % open" safety mechanism being triggered.
- Supply air temperature control (all fresh air):
The V3000 regulates with a Proportional algorithm so that the measured supply air temperature tends towards the setpoints
(P02 or P03).
If the hot valve opens fully, or if the frost protection thermostat (given by P52 = 10), the valve closes and the fan is switched off
immediately.
If the unit has a display terminal, the "Fro" information is displayed upon the Frost protection being triggered by the safety
thermostat. An adjustable spanner appears upon the "cold valve 100 % open" safety mechanism being triggered.
11 - FRESH AIR
Parameters P00 and conguration procedure:
●Diagnostic d01 and d02
The V3000 may perform the master/slave function via 3 different ways:
M aster/slave by hot/cold authorisation (P00 =1 on master, P00 = 2 on slaves). Each controller works according to its own
temperature measurement. A slave can only heat if the master is heating. A slave can only cool if the master is cooling.
This function can take into account local temperature variations inside the same room.
Master/slave by measured T°C mirror effect (P00 = 1 on the master, P00 = 3 on the slaves) The master sends its own
temperature measurement to all slaves. All the devices in the room therefore work with an identical measurement.
Master/slave by actuator position mirror effect (P00 = 1 on the master, P00 = 4 on the slaves), the master sends the position of
its outputs to all the slaves. All the devices in the room therefore work with the same outputs position (valves, electric heater,
fan).
NOTE:
Do not use this configuration when there are units in the same room which are :
- A different size, and
- Equipped with HEE motors (and therefore have different speed thresholds)
- In this case, use the configuration P00=3 on the slaves.
In these 3 cases, the temperature setpoints, and the operating mode are the same on all the devices of the same master/slave
function.
With regards to the ventilation speeds, the first 2 authorise different speeds on the master and corresponding slaves if the
Auto position is selected on the master.
The master/slave function is performed directly, with no need for the presence of a central management unit. It is sufficient to
have a KNX supply and a bus meeting the KNX specifications (see Manual NA 08.51):
- The bus must be fed by a standardised KNX supply.
- Use KNX certified cables
- Wiring diagram (see manual NA 08.34)

EN - 13 EN7515935-00

●Configuration method for Master/Slave operation
The connection bus between the controllers must meet the KNX specifications and be fed by a KNX supply.
This configuration is performed using a wall-mounted display terminal (using 2 display terminals is advised).
Before configuring, all controllers connected to the KNX bus must be switched on (even if they are not affected by the master/
slave).

2 - Case of a Master unit with several slaves:
- 1 master must be associated with 1 slave only
- This must therefore be repeated as many times as there are slaves
- Perform the same operation as in paragraph 1 with the first slave .
- Do the same operation as in paragraph 1 with all other slaves associated with this mastere.
- Starting from the 2nd slave configuration lasts 30 seconds to 1 minute
Note: Allow a maximum of 15 slaves for 1 master unit.
3 - Verify configuration via diagnostics d01 and d02
- d01 relates to the master
- d01 gives the address of the master on the bus, for instance: 1
- d02 relates to the slave
- d02 enables you to check which master is associated with the queried slave. All slaves with their d02 at 1 are associated
with master no.1.

Label
The radio-frequency remote control can only be used with a radio receiver built into the terminal unit.
This remote control enables you to remote control (up to 10 m range) a fan coil unit equipped with a radio-frequency receiver.
This radio-frequency receiver is tted in the factory on the terminal unit. Its design enables it to be put in the room itself, if
necessary.
The features and use of this remote control are the same as for the user display terminal.
The receiver and remote control periodically exchange information (return air temperature value, setpoint value, ventilation
speed…).
These exchanges may take longer than with a wire terminal and need a few seconds.
Batteries: the V3000 system CIAT remote control operates with 2 LR03 alkaline batteries (provided). It is advised that these
batteries are replaced once a year. (depending on the use).
●Configuration of the remote control with its radio-frequency receiver
If the remote control is not associated with its radio receiver (in this case the remote control displays CF1):
- Upon switching on, the radio-frequency receiver LED ashes rapidly.
- If this is not the case, the radio-frequency receiver has already been congured. In this case, refer beforehand to paragraph
“Removing links” below.
- Switch the radio receiver to conguration mode, pressing its button for 3 seconds until the green LED starts ashing more
slowly.
- On the remote control:
- Remove the insulation tab on the batteries to switch it on.
- The display will then be "CF1" (Configuration Menu).
- If "CF1" does not appear, enter the configuration menu, holding the 2 buttons and or 5 seconds.
- "CF1" means that no radio receiver is associated with the remote control.
- Then on the remote control press the button until "Add 1" appears on the screen.
- The rest of the conguration is performed automatically (around 5 seconds).
- When conguration is complete, the remote control display returns to its normal screen (temperature display…).
- The LED on the radio receiver goes out.
Note 1:
The remote control may not return to its normal display, but may return to the "CF" conguration menu:
- If CF2 is displayed, the pairing process has been completed correctly. Allow the remote control to go to standby before
using it.
- If CF1 is displayed, the pairing process has failed; it is therefore necessary to restart the pairing process by clearing any links
created previously (see the paragraph entitled "deleting links between the remote control and the receiver").
Note 2:
* The LED on the radio receiver is lit once it receives an order from its associated remote control.
* Once congured, the button on the radio receiver enables you to start/stop the fan coil unit on which it is tted.
13 - RADIO-FREQUENCY REMOTE CONTROL (SET-UP)
EN7515935-00 EN - 16

In parallel, the symbol displayed on the remote control reacts according to the fan coil unit status. This enables you to check
that the receiver and its remote control have been "coupled".
To remove links between a remote control and a receiver already associated.
Switch the radio receiver to conguration mode, pressing and holding its button for around 10 s, until the LED starts ashing
rapidly. "Decoupling" is executed automatically
Then on the remote control, enter "cong" mode by pressing the ventilation , and standby , buttons simultaneously, until
"CF2" is displayed on the screen.
Press the button until the remote control displays "del".
The rest of deconguration is executed automatically.
When deconguration is complete, the display will return to "CF1".
●Using the radio remote control
After 30 seconds without use, the remote control will go into standby (display switches off) so as to save the batteries.
To "wake" the remote control, press any button.
A horizontal dotted line (-----) ashes on the screen while the remote control synchronises with its receiver (this will take a few
seconds).
●Battery replacement message
If the message "bAt" appears for a few seconds (instead of the ashing dotted line mentioned above) when the remote control is
woken up from standby mode, replace the batteries.
●Master/Slave configuration with the radio-frequency remote control::
1) The KNX bus is present between the Master and Slaves, in this case the configuration procedure is the same as that
described on page 13.
2) No bus is wired between the Master and Slave, in this case it is possible to control up to 8 terminal units with a single remote
control (each terminal unit must be equipped with a radio-frequency receiver).
To configure
- Set P00 to 0 on all the controllers in the master/slave loop (default factory setting).
- Initially, congure the remote control with the 1st radio receiver, as per the procedure described above.
- This radio receiver thereby becomes the "master", and it will indicate to the remote control all information necessary for its
operation.
- Switch receiver no.2 (slave) to "coupling", making it ash slowly using button (hold for around 3 seconds).
- Enter the remote control Conguration menu (button or ) for 6 seconds)
- The display turns to CF2: this means that the master is correctly congured and that you can congure a slave.
- Press : "Add 2"
- The conguration is executed automatically.
- At the end of the conguration: the remote control returns to its normal display and the receiver LED goes off.
- Restart the operation for the other slaves, up to a maximum of 6 terminal units.
Removing links between a remote control and several receivers:
- Start by "decoupling" all the radio receivers by pressing their respective buttons for more than 10 seconds (LED ashing
rapidly). Deconguration is automatic.
- On the remote control enter the conguration menu ( and for 5 seconds) until "CF2" is displayed.
Press , "dEL" appears.
- Wait until the display turns to "CF1"
- All of the receivers and the remote control are "decongured"
