2 - V300

CIAT's V300 control is designed for use with system-powered comfort units (AHUs, cassettes, etc.) in 2-tube, 2-tube/2-wire and
4-tube applications using recirculated air

It can be used to follow a time schedule (connected to the V300 zone timer as an option) and operate using a master/slave
function. It controls 230 V thermo valve actuators.

The V300 system comprises a controller integrated in the comfort unit and a user terminal for adjusting the setpoints and
operating modes.

The terminal is available in a wall-mounted wired version (to be connected to the controller by the installer), a flush-mounted
version (assembled and connected in the factory), and a radio-frequency version (terminal + receiver supplied in kit form)

Main functions:

- PI action

- Controlling a 3-speed or HEE fan, automatically or manually.

- Automatic heating/cooling switching with changeover sensor (2-tube application).

- 2 potential-free inputs for window switch, alarm or timer.

- 4 operating modes: Comfort/Economy/Frost protection/Off

Eubac certification

• The V300 controller is Eubac-certified under licence No.215472

• The corresponding CA values are as follows:

Applications: → 2-tube: Heating: 0,1 Cooling: 0,1
→ 2-tube/2-wire: Heating: 0,2 Cooling: 0,1
→ 4-tube: Heating: 0,1 Cooling: 0,1

• Labelling: AA

Note:

- These values are obtained with the CIAT NTC 10k Ω return air temperature sensor at 25°C

- These values can be viewed on the Eubac certification website: http://www.eubaccert.eu

Deadband adjustable by 2 K min. Deadband adjustable by 2 K min.

When exiting the heating or cooling mode, the fan continues to operate for 2 minutes, thereby ensuring post-ventilation of the unit.

The potential electric heater power is modulated by a time-proportional signal using a 4-minute time base.
All calculations take place in the controller. The control terminal is used to adjust the temperature setpoint, switch between
automatic and manual ventilation, switch the unit on or to standby and, if applicable, to measure the room temperature.
The connection between the terminal and the controller is a 4-wire connection (2 shielded twisted pairs) with the shielding
connected to the comfort unit earth. (see pp.10 & 16)
Regulation on the air:
The regulation V300 also allows a functioning on the air (without gate(crack))

- In this case, the use of pumps of condensats on devices equipped with this mode of regulation stays of the responsibility of the

customer and/or the installer in case of dysfunction of this pump (risk of overflowing of the tub(ferry,high school diploma) of the
condensats of in the permanent irrigation of the cold battery(drum kit)).

- For vertical units equippedwith this control principle, the effect of the continuous radiation from the exchanger coil on the sensor

vill not enable the control system to function correcty. It is the customer's responsibility to find a suitablelocation for optimum
positioning of the sensor and satisfactory operation of the units.

10 - MEASURING THE TEMPERATURE

The V300 offers the possibility of controlling the air temperature via a return sensor or a room sensor (P11).
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.

EN - 11 N 12.54 D

20 cm
min.

150 cm

150 cm

The sensor can be chosen using setting P11 (=0: return air 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 d07.

The sensor measurement can be corrected by means of parameter P12 (return sensor) or P13 (room sensor).

11 - CHARACTERISTICS OF THE SENSORS USED BY THE V300

All the sensors used by the V300 (return, changeover) have the same specifications

Resistance Ohms 22 050 17 960 14 690 12 090 10 000 8 313 6 940

12 - MEASURING THE WATER TEMPERATURE

Two-tube heating/cooling comfort units may be fitted with a water temperature sensor (or changeover sensor). It must be
positioned by the installer upline of the 4-way valve (water network end). It is fixed to the pipe using electrician's clips and located
underneath the pipe's thermal insulation.

Sensor

Insulation

Valve motor

3-way valve with
built-in bypass
(often called a
4-way valve)

- Changeover operating algorithm:

• If the changeover sensor measures a water temperature greater than 7°C (P48 adjustable) at room temperature, the water is

deemed to be hot.

• If the changeover sensor measures a water temperature lower than 4°C (P49 adjustable) at room temperature, the water is

deemed to be cold.

• If the changeover sensor measures water temperature between these two values, the water is deemed neutral.

- Changeover operation with water at neutral temperature:

In this scenario, and if the controller requirement is confirmed, the V300 launches a test cycle on the valve 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 V300 keeps the same status

- If this temperature varies and returns to the conditions described above, the V300 re-authorises its control cycle.

NA 12.54 D EN - 12

Warning: 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 P47 = 1, if nothing is connected between terminals S2 and ┴, 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 P47 = 0, the controller waits for the water temperature value from the V300 zone timer in order to start heating or cooling (if it
does not receive a value, it will automatically operate in "heating mode" to ensure safe heating and frost protection, or in "cooling
mode" on 2-tube + 2-wire applications).

13 - RADIO-FREQUENCY TERMINAL

. The radio-frequency terminal can only be used with its radio-frequency receiver.
. The radio-frequency receiver is supplied in kit form and must have been pre-installed on the comfort unit using the support

bracket supplied with the kit

. The terminal functions are identical to those of the wired wall-mounted terminal. This is fixed to the wall in the same way (see

dimensions and drilling instructions for the unit).
. The receiver and the terminal periodically exchange information (setpoints, ventilation speed, etc.)
These exchanges may take longer than with a wire terminal and need a few seconds.

. The radio-frequency terminal operates with 2 LR03 type alkaline batteries (supplied). These batteries should be replaced once

a year (depending on use).
Battery

- 2 LR03/AAA 1.5V alkaline batteries

- Match the +/- polarity

- The batteries supplied are not rechargeable

Warning : there is a risk of explosion if the battery is replaced with the wrong type. Dispose of used batteries in accordance
with the instructions. When replacing batteries, make sure the product is correctly and completely refitted.

IMPORTANT for Switzerland: Annex 4.10 to the norm SR 814.013 is applicable to batteries.

EN

Configuring the terminal with its receiver

. Radio receiver:

Indicator 1 (blue) : - Flashes = receiver not paired rapid flashing = receiver not paired

- On = pairing (or unpairing) in progress slow flashing = pairing (or unpairing) in progress

- Off = receiver paired

Indicator 2 (orange) : - Flashing when information is sent or received regular flashing = loss of communication between the

receiver and the terminal.

Indicator 3 (green) : - Indicates operation in comfort mode (once pairing is complete)

- The receiver key then acts as the unit's On/Off key

- Comfort operation: indicator on; off for all other modes.

. If the terminal is not linked to a receiver, the display shows: "CF 0"
. If the terminal shows "CF 1", it is linked to a receiver:

to access the configuration menu, press and hold the key for 5 seconds.

. When powered up :

- Indicator 1 (blue) on the receiver flashes rapidly

- Set the receiver to configuration mode by pressing and holding its key for 5 seconds: indicator 1 (blue) flashes slowly
. On the terminal :

• Press the key: the display shows "Add": pairing starts (approximately 5 to 8 seconds)

• When the sequence is complete, the terminal display returns to its normal screen (temperature display, etc.).

- Indicator 1 on the terminal goes out

- Indicator 3 on the terminal comes on if comfort mode is active on the terminal (off for all other modes)

- This allows the user to check the communication between the unit and the terminal using the receiver key (which acts
as the On/Off key) via the current mode display.

- The display will then show "CF 1" in the configuration menu

- To delete the links between a terminal and a receiver which are already linked:

- On the terminal: enter configuration mode key for 5 seconds) until the display shows "CF 1"

EN - 13 N 12.54 D

Press the button The display becomes "del"

Deconfiguration is done automatically. The sequence is completed as soon as the display becomes "CF O". From this moment,

the terminal and its receiver are unapplied

In the case or "CF2" appears on the display(posting), it indicates that the désapairage of the terminal was made while the

communication with his(her) receiver was broken.

In this case of figure :

Rest(Support) again on the sideline So as to have the display(posting) " CF 0 " (CF 0 = désapairé terminal).
Désapairer the receiver in a individual way: rest 5s the button Of the receiver. The blue clairvoyant(light) (1 ) quickly flashes.
The receiver is désapairé.

. Using the remote control:

- After 30 seconds without use, the terminal will go to standby (display switches off) to save the batteries. To "wake"
the terminal, press any key. The display "----°C" appears on the screen, flashing for a few seconds, while it synchronises with its

receiver.
. Battery change indicator:

- When the terminal has been woken, if "bAt" appears for a few seconds (rather than flashing "----°C") the terminal

batteries must be replaced.

- In the case or "beats" if fixed speed(look), piles cannot assure(insure) any more the food(supply) of the terminal.

Compulsory change of piles.

14 - MASTER/SLAVE FUNCTION

A master can control up to 15 slaves.
Two wires + shielding lead from the master unit to the first slave. Two wires + shielding lead from the first slave to the second
slave, etc.
Wires do not have to lead out from the last slave. The distance between two controllers must not exceed 30 m (see cable
characteristics on p16)
The master communicates the following information to the slaves:

● Setpoints

● Air temperature

● Water temperature

● Current mode

● Manual ventilation speed

● State of inputs D1 and D2.

It is possible (via P11) to set the slave units on the return air sensor (e.g. open plan offices).

A slave must not have a room unit.

The operation resulting from the combination of the Off, Frost protection, Economy, Comfort, Window open states between the
master and the slave is designed to reduce energy consumption to the minimum.

Starting up a Master/Slave unit:

. The Master and Slave units are detected automatically.

→ The master is the unit at the head of the master/slave bus
→ When the loop is powered up, the master automatically detects the slaves connected downstream of it (see

wiring diagram below)

→ Check the number of slaves connected to the Master via diagnostic d00
→ If the number does not match, check the wiring
→ Set any parameters on the Master (new setpoint, etc.); they will automatically transferred to the connected slaves

(see list pp 7 and 8)

→ Set any parameters on the Slaves (control on return sensor, etc.)

Two scenarios:

● If the setting is entered on the first Slave in the loop, all the slaves located below it will have the same settings.

● If only one slave is affected: temporarily disconnect its bus to separate it during the setting procedure.
→ It is possible to transfer all the parameters (see list pp 5 and 6) from a master to all of its slaves (when replacing a

Slave controller): see p55 = 3

→ If the master/slave connection is broken, all the slaves located downstream of the break will switch to "Standalone"

mode and retain their operating status during the break.

→ The master terminal will then display the symbol; the d07 will provide the information on the "loss of

communication with the slaves": d07 = 1.0.0 (see § Diagnostics p9)

NA 12.54 D EN - 14

. It is possible to diagnose units still being controlled by the terminal and find out via the d00 how many slaves are still connected
by pressing the key.
. The limit for a master/slave loop is 15 slaves max. per master (see schematic diagram with maximum cable length between
master and slave)

. If a slave still has a room terminal, check that P09 = 2 imperative.
It will display the state of this Slave controller + the T° measured by the Master (if room sensor priority) or the T° measured by its

own sensor (if return sensor priority), as the keypad keys are inactive (parameters and diagnostics for this slave are accessible
for diagnostic purposes)

Inputs D1 & D2:

. If Input configured with "Alarm" (condensate pump, motor fault, etc.):
→ If alarm on the master:

The master is powered off and displays and ; the keypad keys are locked.

The slaves on the loop continue to operate in the last state indicated by the Master.
The slaves remain controlled by the V300 Zone timer, if included.

→ If there is an alarm on one of the slaves:

Only the slave concerned is powered off, the other units continue to operate as per the orders from the Master and its room
terminal.
. If the Input is configured to one of the 4 operating modes:

→ If triggered on the master:

The entire Master/Slave loop switches to the mode defined by the input configuration.
Only a lower mode may be set using the wall-mounted terminal (depending on the sleep button configuration)

For window switches: (Frost protection mode):
They must all be connected in series to the Master

→ If triggered on one of the slaves:

Only the slave concerned switches to the mode defined by the input configuration.

Setting the parameters on a Master/Slave loop:

Modifying a parameter on the Master unit will also modify the Slave unit

→ See Parameters table including the list of parameters sent from the Master to its Slaves (pp 7 & 8)
→ Warning: Modifying one parameter directly on a slave in the loop will modify the same parameter on all the slaves

located below it. To modify only the slave concerned, disconnect the bus (via the quick connector) and connect a terminal to carry
out the operation.

15 - PI CONTROL

The control parameters (proportional band, integral time) are preset in the factory. Precise values have been validated in the

laboratory and enable "Comfort" operation in most comfort unit applications. Modifications to these remain the user's responsibility.

Deadband ventilation

In the comfort operating mode, the deadband ventilation is set in the factory as follows:

. Comfort mode (P19): 0 Fan stoppage (if controller with room sensor) or 1: periodic restarts (if controller with return sensor).

It is possible either to cut off the ventilation after 2 mins of post-ventilation (P19 = 0), or have constant low speed ventilation (P19
= 3), or have constant ventilation in the summer and for it to cut out in the winter (P19 = 5), i.e. ventilation on every 30 mins for 1
minute (P19 = 2).

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 (see details of P19 in the parameters table).

Note: For air control (without valves), make sure that P19 is set to 0 to avoid problems with overheating or cooling caused by the
ventilation.

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. Parameter

P54 enables you to set a timer between 1 hr and 12 hrs, or to prohibit any comfort override (P54 = 0). This function can be
disabled (P54 = 13). It is generally used with a zone timer (see corresponding instructions)

Operating mode activated by standby key

Depending on parameter P08, the sleep button can be pressed to switch between the controller's 4 operating modes: Comfort,
Economy, Frost protection and Off.
2-pipe + radiator application or 2-pipe + electric convector application
The control enables one radiator equipped with a 230V thermostatic valve or an electric convector (230V/2000W max) to be

actuated via P21 = 2

EN

In this case, during the heating sequence, the V300 control stops ventilation
of the comfort unit and triggers the connected electric convector or radiator valve in on/off mode.

The electric convector must then be wired directly to the V300 control
via the dedicated output for the electric coil (230V/2000W max) / the 230V thermostatic valve can be actuated either by this same

output or by the free valve output (P25=1)

16 - UNIVERSAL INPUTS

The V300 controller is equipped with two configurable potential free inputs. These two inputs, D1┴ and D2-┴, are supplied 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
This input can be configured using parameters P14 and P16
P14: Action direction of contact, NO or NC
P16: Enables the user to slave controller operation to contact opening or closure, with the possible set-up below:
0: Inactive
1: Frost protection
2: Economy
3: Alarm

4: LS* air purification

5: MS* air purification
6: Off

. Universal input D2

This input can be configured using parameters P15 and P17

P15: Action direction of contact, NO or NC

P17: Enables the user to slave controller operation to contact opening or closure, with the possible set-up below:

0: Inactive
1: Frost protection
2: Economy
3: Alarm

4: LS* air purification

5: MS* air purification
6: Off

. Note D1 and D2:

- Make sure that the two D1 and D2 inputs are always configured differently (to avoid the risk of conflict between identical values

on two separate inputs).

*Note:

- Warning: LS or MS Purification function not compatible with "Air" control (without valves)

17 - CONNECTING THE FRAME CONTACT

Connecting the frame contact

● Parameter P16 or P17

Frame contact to be wired to input D1- ┴ or D2 ┴ depending on your device's configuration (refer to the corresponding wiring
diagram).

Regulator

Window switch

The cable used has a maximum length of 10 m, and minimum section of 0.9 mm². It is recommended to use a twisted and
shielded cable.
Note: the window switch must be insulated from earth. If there is shielding present, it must be connected to the comfort unit earth.

● Direction of window switch

(default)

● If the window is open and the controller has a display terminal, this will display " " instead of the temperature and the keys

will be locked.

Note:

- When the window re-closes, the unit restarts automatically

- The terminal display will return to "normal" after 10 seconds, the time it takes for it to synchronise with the controller

Note: for a Master/Slave loop, the window switches must be connected to the Master unit (all contacts in series, normally
closed).

Maximum: 30 offices (corresponding to Master and/or individual units)

The comfort units (ductable, air handling units or cassettes), which are all independent, are equipped with V300 control.
Each comfort unit has its own comfort temperature sensor.

A centralised timer comprising a zone controller and a wired LCD terminal in an electrical cabinet outside the zone enable remote

centralised management of this loop. A terminal is connected to this controller for adjusting and operating the system.
The timer is integrated in this controller to ensure time management of the Comfort/Economy/Frost protection/Off modes.

. The terminal is used:

→ To set the integrated daily/weekly timer
→ To distribute all the comfort units across 6 self-contained zones
→ To determine, for each zone, the hourly management of the 4 modes (Comfort/Economy/Frost protection/Off)
→ To set, for each zone:

• The heating and cooling Comfort setpoints

• The heating and cooling Economy setpoints

• To override the time slots per zone, or for the entire building.

EN

. The "zone" controller therefore enables management of the entire building for:
→ The locally authorised setpoint shift range
→ Adjustment of the comfort restart time on the local wall-mounted terminal
→ Possible central changeover
→ Advance heating restart based on the outdoor temperature (depending on options)

Refer to manual No.14-13 for all possibilities and settings for the V300 zone timer.
