for the GENERAL WARNINGS.

Controller with LCD screen for universal installationThe iK controller can be used to set: operating mode (OFF / cooling /

heating / AUTO / FAN), fan speed (Max / Med / Min / AUTO), tempera-

ture set point by electronic thermostat. Combined with the (i)-HB power

board, it manages the main valve (cooling/heating - 2-pipe system) and

additional valve (heating mode - 4-pipe system). Control of ON/OFF

and modulating valves with 0-10V signal or 3-position valves (230 Vac

or 24 V). Management of air temperature and minimum water tempera-

ture probes. Management of Master-Slave local networks with up to 8

LIFE series fan coils.

The user interface can be integrated into centralised Building Manage-

ment Systems (e.g. Climaveneta Idrorelax) compatible with the Modbus

protocol.

The iK controller can also display and configure user operating parame-

ters; moreover, the parameters set on other controllers and/or (i)-HB

LIFE power boards connected to the local network can also be dis-

played and set.

The controller is quick and easy to install, thanks to the two-wire con-

nection and either wall mounting or plug-in assembly on the unit.

The iK interface controls fan speed continuously in AUTO speed mode.

When iK is used with i-LIFE fan coils featuring continuous modulation,

the speed can be set manually based on six preset steps; when used

with a-LIFE and a-LIFE HP fan coils, on the other hand, three manual

speed settings are available.

The iK controller is powered directly by the (i)-HB power board installed

on the side of the fan coil.

To switch the iK interface off, press the ( ) button.

Fan operating mode Fan speed can be set manually on the iK controller, pressing in

correspondence of .

- fan is always working according fan speed set (auto fan speed is not

active).

- the cooling mode valve is always OFF;

- the heating mode valve is always OFF;

Automatic fan speedFan speed is controlled automatically based on the difference between

the set point and the room temperature.

The greater the difference, the faster the fan speed.

Periodical fan operation This function prevents air stratification and helps the air temperature

probe measure the room temperature more accurately. i.e. closer to the

temperature perceived by the user.

This function is active in both cooling and heating mode.

The unit always operates at minimum speed.

Hot Start functionAvailable in heating mode only.

This function starts the fan only if the water is warm enough (T 32C),

to avoid blowing cold air into the room.

This function is not available when the electric heater is installed.

The Hot Start temperature can be set by parameter, see the table of

configurable parameters.

Too Cool functionAvailable in cooling mode.

This function starts the fan only if the water in the coil is cold enough (T

18 C).

The Too Cool temperature can be set by parameter, see the table of

configurable parameters.

Weekly timer operationThe iK controller can operate based on a weekly timer, using four preset

programs and one custom user program.

The set point is managed using two temperature levels (T1, T2, OFF)

over set time intervals.

The iK thermostat used preset temperature levels based on the weekly

timer settings and the operating mode (cooling or heating).

iK controller backlightingThe iK controller has an LCD display backlit by white LEDs.

The screen switches off automatically 20 seconds after the last button is

pressed; after the set inactivity time, screen brightness is reduced auto-

matically.

If the backlighting is off, pressing a button does not activate the associ-

ated function, but rather switches the display back on; pressing the but-

ton again or another button activates the associated function. It is possi-

ble to set backlighting and time of automatic switching off.

Electric heatersThe LIFE fan coils can be fitted with electric heaters with various power

output ratings. The following control logic can be selected:

- 2-pipe unit with control heater = the electric heaters are the only

source of heat;

- 2-pipe unit with supplementary heater = the heaters augment the

heating capacity delivered by the main coil in heating mode.

The electric heaters can only be installed on the production line in place

of the additional coil and only for three-row fan coils.

Heater management is set directly using the dipswitches on the (i)-HB

LIFE power board installed on the side of the fan coil.

Units with the electric heaters on can only operate at the preset maxi-

mum speed.

Building Management System connectionThe iK controller can be integrated into a BMS for centralised manage-

ment and supervision (e.g. Climaveneta Idrorelax) using the Modbus

RTU protocol, after having installed the RS485 kit - interface for cen-

tralised management systems on the (i)-HB LIFE power board fitted on

the side of the fan coil.

Sleep function

The Sleep function is activated by pressing the button for 5 sec-

onds. The controller then behaves as follows:

COOL mode- Fan at minimum speed

- Operating at minimum speed, the unit automatically increases the set

point by 1C at 1 hour intervals for a total of 6 hours.

The fan coil is then automatically switched off.

- The controller remains OFF until the user next selects the desired

operating mode.

- If during the Sleep function the user changes any settings on the key-

pad (set point or fan speed), the controller will operate according to

the new settings made by the user, disabling SLEEP function.

HEAT mode- Fan at minimum speed

- Operating at minimum speed, the unit automatically reduces the set

point by 1C at 1 hour intervals for a total of 6 hours.

The fan coil is then automatically switched off.

- The controller remains OFF until the user selects the desired operat-

ing mode.

- If during the Sleep function the user changes any settings on the key-

pad (set point or fan speed), the controller will operate according to

the new settings made by the user, disabling SLEEP function.

The following preset parameters apply to both the COOL function and

the HEAT function:

- Step: temperature increase / decrease for each unit of time.

DEFAULT = 1C

- change set point t: time after which the set point is changed.

DEFAULT = 1 hour

- end function t: time after which the Sleep function ends.

DEFAULT = 6 hours

The Sleep function parameters cannot be modified by the end user.

MASTER-SLAVE INTEGRATION

The iK controller can manage Master-Slave systems with up to 8 LIFE

fan coils using a simple two-wire connection.

The iK controller can be set as:

- "Global" user interface: the controller acts as the Master and man-

ages operation of all the units. All the fan coils connected to the net-

work will operate in the same mode.

- "Private" user interface: if one unit needs to operate in different condi-

tions from the Master controller, the controller managing this fan coil

can be enabled as a Slave and some operating modes can be set dif-

ferently from the Master.

For this configuration, the address of the controller set as Slave and

the corresponding power board installed on the fan coil must be set

using the dipswitches.

INSTALLATION

The controller must be installed by qualified personnel.

- Before installing the controller, power to the fan coil must be discon-

nected.

- The iK controller kit with LCD screen can be installed either as a plug-

in device (on the unit) or on the wall.

Installing the iK controller on the unit- Remove the casing as illustrated in the fan coil installation manual.

- Run the wiring through the opening on the controller support base.

- Connect the cable (B) to the (i)-HB power board as shown in the

wiring diagram.

- Press the controller lightly to couple it onto the plastic support.

Make the connections as shown in the wiring diagram

Installing the iK controller on the wallThe controller must be installed by qualified personnel. For optimum

room temperature control, the wall-mounted iK controller must be

installed in a position that represents the reference temperature for the

home. For correct installation, remember that the iK wall-mounted elec-

tronic thermostat:

- must be installed on a wall, where possible on the inside, that is not

crossed by hot or cold water pipes;

- must be mounted around 1.5 m from the floor;

- non not be installed near doors or windows, cooking appliances, radi-

ators, fan coils or in general affected by situations that may cause dis-

turbance to the temperature measured.

To fasten the iK controller to the wall, proceed as follows:

- separate the top shell from the bottom shell by pressing the plastic tabs

with a screwdriver, levering it on catches;

- use the bottom shell as a drilling template to mark the holes on the wall;

- drill the holes on the wall;

- run the electrical connections through the opening in the middle of the

bottom shell;

- after having completed the connections, replace the top shell on the

bottom shell.

The iK controller has been designed for assembly in the following types

of flush mounting switch boxes:

- For brick walls, 2- or 3-gang flush mounting boxes, fastening the con-

troller directly to the 2-gang box and using the fastening bracket for

the 3-gang box.

- For light walls (e.g. plasterboard) 1- or 2-gang boxes, fastening the

controller directly to the box and making sure any parts of the flush

mounting box that protrude from the outline of the controller are paint-

ed the same colour as the wall.

The connection cable between the wall-mounted controller and the

fan coil must be continuous; if joints are needed, these must be sol-

dered and suitably protected.

Connection cables must run in separate conduits from the power

cables (230 Vac).

Never connect more than two wires to the same terminal on the wall-

mounted controller.

The controller shown in the drawings is purely indicative and used as

a guide for installation. The unit actually supplied may differ from the

illustrations.

Water and air temperature probes are required for correct operation of

the iK interface for universal installation.

The probes are wired directly to the (i)-HB power board.

Water temperature probe installation- Run the water temperature probe through the holes on the side of the

fan coil.

- If no valves are installed, insert the water temperature probe (black

cable) into the special probe socket on the rows of the main coil (2-

pipe system). If the fan coil has been configured for 4-pipe systems,

install the additional water temperature probe in the socket on the

additional heating coil.

- If on the other hand valves are installed, insert the water temperature

probes in the corresponding sockets, based on the type of system (2-

pipe or 4-pipe).

For correct installation of the water temperature probe, use conduc-

tive paste to improve contact between the probe and the socket and

fasten the probe with a clamp.

Incorrect positioning of the water temperature probe will affect cor-

rect operation of the Hot Start and Too Cool functions.

Disconnection of the water temperature probe disables the Hot Start

and Too Cool functions.

Air temperature probe installation- If the iK controller is installed on the wall, the air temperature probe

inside the controller is used.

The remote air temperature probe does not need to be installed.

- If however the iK controller is installed on the unit, the remote air tem-

perature supplied with the iK controller kit must be used, connecting it

as shown in the wiring diagram. When connected, the air temperature

probe is automatically recognised by the power board.

- To enable the remote air temperature probe, set the dipswitches as fol-

lows:

- iK controller interface: DIP 4 ON

- (i)-HB power board: DIP 4 ON

When positioning the probes, remember that the (i)-HB power

board is located on the side of fan coil, as shown in the figure.

The air/water temperature probes are recognised using plug&play

logic; no parameters need to be set following installation.

ELECTRICAL CONNECTIONS

Make sure that the main system switch is in the OFF position before

performing the electrical connections.

Power to the iK interface is supplied directly by the (i)-HB power board

installed on the side of the fan coil.

A two-wire bus connection is used, no other connections are needed.

Recommended cable BELDEN 9841 AWG24.

Minimum cross-section allowed AWG24 (e.g. BELDEN model 9841

shielded cable). Maximum cross-section allowed AWG20 (e.g. BELDEN

model 9272 shielded cable).

The two-wire bus connection is used for both communication and

power supply to the interfaces.

The expansion kits shown on the connection wiring diagram are

additional boards used in combination with the (i)-HB power board

and have their own terminal block.

Weekly timer operating logic

The weekly timer works based on the following operating logic:

Heating mode

If T < T1 or T2 system control active

If T > T1 or T2 set point reached

Cooling mode

If T < T1 or T2 set point reached

If T > T1 or T2 system control active

The operating temperature levels are activated based on the signal

from the weekly timer program set for the different time intervals:

- Temperature set point T2: levels T1 and T2 on;

- Temperature set point T1: level T1 on;

- OFF: both temperature levels are off;

The temperature levels flash in relation to the current time:

- If the temperature set point is T2, T1 and T2 flash (1.5 s ON / 0.5 s

OFF);

- If the temperature set point is T1, T1 flashes (1.5 s ON / 0.5 s OFF);

- If temperature control is OFF, T1 flashes (0.5 s ON / 1.5 s OFF);

In weekly timer operation, the display shows the operating temperature

set by the current program.

If the iK controller is working in Manual operating mode, the display

shows ; no timer program active.

When using the weekly timer functions, the fan speed is controlled

automatically.

In Master-Slave configuration, only the Master controller can activate

the weekly timer. The operating program is applied to all the units

connected in the local network. If settings are modified on the Slave,

when the next time interval starts, the Master controller applies new

settings defined by the timer to all the units connected in the local

network.

Fan coil connection and address setting procedureTwo types of Master-Slave networks are available:

- Master management: only one Master iK controller (global interface)

is installed in the network, and manages all the units connected in the

same mode.

- Master - Slave management: the network features one Master iK con-

troller (global interface) and a series of Slave iK controllers (private

interface), the latter which change some of the operating parameters

on the unit theyre connected to, independently of the Master con-

troller.

Master management - Only the iK interface installed manages all the units connected in the

same operating mode.

- Connect iK and the (i)-HB power boards as shown in the Master man-

agement wiring diagram.

- Set the address using the dipswitches on iK and (i)-HB with Bus add

= 0, as indicated. All the devices will have same address.

MASTER SLAVE NETWORK INSTALLATION

The iK controller can manage Master-Slave networks with up to 8 Cli-

maveneta i-LIFE/a-LIFE fan coils, using a simple two-wire connection

between the units.

The iK controller installed in a local network can be set as:

- MASTER: operates as the "global" user interface

The controller manages operation of all the units. All the fan coils con-

nected to the network will operate in the same mode.

- SLAVE: operates as a "private" user interface.

If a fan coil needs to operate in different conditions from the Master,

the controller managing this fan coil can be enabled as a Slave and

some operating modes can be set differently from those set on the

Master controller. The controller to be enabled as a Slave, its address

needs to be set using the dipswitches on the i-(HB) power board and

on the iK controller.

Master-Slave networks can connect the following controllers at the

same time: EK(W), iK (controller for universal installation).

The connection and address setting procedures are independent of

the type of interface installed.

In of a local network with Master management, the (i)-HB power

board combined with the RS485 kit - interface for centralised man-

agement systems, is automatically defined as the Master (see the

wiring diagram below).

To connect the fan coil in a local network, proceed as follows:

- LIFE fan coils are integrated into Master-Slave networks using a two-

wire connection.

- Connect the power boards installed on the side of the fan coil in paral-

lel (see the enclosed diagrams).

- Connect the controllers to the power boards with a two-wire connec-

tion (see the enclosed diagrams).

The maximum length of the Master-Slave network is 35 metres of

bus cable (shielded cable).

Shielded twisted pair cable (two wires plus shield). Recommended

cable BELDEN 9841 AWG24.

Minimum cross-section allowed AWG24 (e.g. BELDEN model 9841

shielded cable). Maximum cross-section allowed AWG20 (e.g.

BELDEN model 9272 shielded cable).

Dipswitches for setting the address:

- The iK interface and the (i)-HB power board installed on the fan coil

have a series of dipswitches for setting the address when the unit is

integrated into Master-Slave networks.

- The dipswitches on the controller and on the power board must be set

as shown in the Master management wiring diagram.

16 GB

- The water temperature is controlled by the probes connected directly to the (i)-HB power board corresponding to the Master interface.

Master - Slave management wiring diagram:

Master - Slave management In Master - Slave management, the iK controllers installed can be

enabled as the Master or Slave interface based on the dipswitch set-

ting. In Master - Slave management, one or more Slave iK interfaces

can be connected to the network. These can set the following parame-

ters for the units theyre connected to:

- Master interface

The iK controller enabled as the Master manages all the units con-

nected in the same mode, defining:

Temperature set point

FAN SPEED

- Slave interface

The iK controller establishes the following for the unit its connected to:

Set point (+/- 2 C from the Master)

Local ON/OFF

The Slave interface only manages the fan coil its connected to.

To assign a Slave interface to a fan coil, set the same address using

the dipswitches on the controller and on the power board.

Example. Slave interface address = Slave fan coil address = BUS

Add 8.

Warning, the same Slave address cannot be assigned to more than

one (i)HB board.

BUS Add=0 BUS Add=8

MASTER SLAVE

HOT START and TOO COOL water temperature control

BUS Add=0 BUS Add=0 BUS Add=0 BUS Add=0 BUS Add=0 BUS Add=0 BUS Add=0 BUS Add=8

- In Master - Slave management the settings on the Slave interface

remain active until changes are made on the Master interface.

- The Slave interface can be set with a different set point from the Mas-

ter, with the value representing the deviation (Slave interface set point

= Master set point 2 C).

The maximum deviation of the set point on the Slave controller corre-

sponds to the temperature knob being turned completely clockwise or

anticlockwise.

The settings available directly on the Slave interface do not require

water or air temperature probe readings.

- The air temperature probes on Slave interfaces must be disconnected

from the corresponding (i)-HB power boards. This means the boards

will automatically read the values measured on the global interface.

- The water temperature probes are used to control the hot start and

too cool functions.

GB 17

LOCAL NETWORK PARAMETER MANAGEMENT

Displaying and setting the parametersThe parameter values set on the various devices connected to the two-

wire bus network can be displayed and set on the iK controller.

The iK controller needs to be connected as shown in the wiring dia-

gram.

The available parameters depend on the device:

- iK - controller with LCD screen for universal installation;

- EK - electronic controller for plug-in installation;

- EKW - electronic controller for wall mounting;

- (i)-HB - LIFE power board for fan coils with electronically commutated

or three-speed fans;

The parameters are managed using the iK interface; use the iK con-

troller already connected to the two-wire bus network.

If other interfaces are connected (e.g. EK, EKW), connect the iK

controller used to manage the parameters to any (i)-HB power board

connected into Master-Slave network, refering to the specific bus

address.

The procedure for displaying/setting parameters is divided into four

steps:

Step 1: enter the access password

Step 2: select the node (controller or power board)

Step 3: select the parameter

Step 4: display/set the parameter value

The password is only entered by the technical service centre for

managing specific parameters in the event of malfunctions on the

units connected to the network.

Parameters available to the user can be displayed and/or set without

entering an access password.

Procedure for displaying and modifying set parameters

Parameter values should only be modified if strictly necessary, as there is no procedure for returning to the initial parameter configuration on the

interfaces and power boards by cancelling the changes made.

ITF: Current interface

CVC: (i)-HB power board for fan coils

To display/set user parameters, proceed as follows:

- Press to switch on the iK controller


- Press + to access parameter setting mode (10 s)

- Step 1 accessed

Step 1: enter access password

- Press to go to Step 2

- USr is displayed user access

- Press to return to the Main screen

18 GB

Step 2: select the node

- Select the required interface or power board

When accessing step 2 the default unit selected automatically is the

node corresponding to the current iK interface used to manage the

parameters or the node corresponding to the Master iK controller in

a Master-Slave network.

The node is displayed depending on whether the iK controller address

has been set (see the section MASTER-SLAVE NETWORK INSTALLA-

TION).

- The identifier of the selected node is displayed

- Press or to select a different node

- The nodes are displayed in a circular sequence (It00,,It08,ItAA,

Fc00,, Fc08, FcAA, It00,)

- Interfaces are identified by Itxx (xx = 00 to 08; current interface

address). The identifier ItAA selects all connected interfaces (e.g.

EK, EKW, iK controllers).

- Power boards are identified by Fcxx (xx = 00 to 08; board

address). Each fan coil connected to the local network is fitted with a

power board. The identifier FcAA selects all connected fan coils.

- Nodes not present in the active two-wire bus network are not dis-

played


- Press to return to the Main screen

The weekly timer time intervals represent the layout of nodes con-

nected to the two-wire bus network. Temperature step T2 displays

the active ITF nodes. Step T1 displays the active CVC nodes. The

levels corresponding to the selected nodes flash.

Anonymous nodes (address = 0) identify interfaces and power

boards connected with Master management. A node that is NOT

anonymous (address not 0), either ITF or CVC, represents to a

Slave unit. If all the fan coils are configured as anonymous (address

0) levels T1 and T2 display the hours (00).

Step 3: select the parameterro

- When accessing this step, parameter P01 on the node set in Step 2

is selected automatically.

- Press or to select a different parameter (Prxx where xx =

01 99, representing the parameter number)

- Press to return to Step 2


- When accessing Step 4, Load is displayed (max 5 s) to indicate that

the ITF is receiving the selected parameter; if correctly received, the

ITF goes to Step 4.

- If the selected parameter is not defined for the specific node, nd is

displayed (2 s)

- If the selected node doesnt respond within the set time, Err is dis-

played (2 s)

The request to read a parameter value must be sent to a specific

node address in order to have a unique response:

- If a specific node is selected, the query is sent to that node;

- If ItAA is selected, the parameter value is queried on the current

interface (ITF);

- If FcAA is selected, the parameter value is queried on the Master

CVC.

GB 19

Step 4: display - set parameter value

- Press or to set the parameter value, within the field of allowed

values (see table)

- The temperature setting field shows the selected parameter value

- Press o save the parameter value. SAVE is displayed (max 5 s)

- ITF awaits reception of confirmation that the value has been saved by

the selected node:

- If the selected parameter is not defined for the specific node, nd is

displayed (2 s)

- If the selected node doesnt respond within the set time, Err is dis-

played (2 s)

- Press to return to Step 3 without saving the parameter value.

If when saving a parameter the iK controller displays Err, this

means that the parameter can only be accessed in Installer mode,

after entering the password at the beginning.

If an individual node is selected, the request to save the parameter is

sent to that specific node, which in turn sends confirmation.

If a parameter is modified after having selected ITAA or FCAA, the

changes are applied to all the interfaces (ITF) or power boards

(CVC) connected to the network.

- LOAD indicates that the set parameter value is being loaded.

- DONE confirms that the new settings have been saved.
