1. General information

The “4-Fun” controller is designed to control the room comfort trough:

- Controlling a 2- or 4-pipe FCU,

- Controlling a chilled beam,

- Controlling floor heating system,

- Controlling lighting,

- Controlling the blinds.

Default factory settings of the “4 Fun” controller are for operation with a 4-pipe FCU

equipped with a 3 speed drive motor (PK1…PK3 or Aout3), heating valve (PK4 or Aout1),

cooling valve (PK5 or Aout2), and the temperature adjustment is facilitated in relation to

the temperature sensor that is built in the HMI controller, as connected to the HMI CON

connector.

The “4-Fun” controller is freely configurable and the configuration of additional functions may be

performed with use of the HMI controller, through the “Service menu/In- and out- functions”.

The “4-Fun” controller may be used as the main, “Master” controller or an auxiliary, additional “Slave”

controller extending the FCU group.

The “4-Fun” controller in the “Master” configuration is the main controller in which all additional

functions can be activated (the sole limit is the number of in/out lines).

The “4-Fun” controller in the “Slave” mode is just an extension of the digital and analogue connectors,

with states that are identical to the states of the digital and analogue outputs of the “Master”

controller.

Each of the “4-Fun” controllers comes equipped with a RS485-1 connector for connection of

primary devices, and a RS485-2 connector to connect the controlled devices.

When configured as a “Master” the RS485-1 connector can be used to connect a BMS system:

Modbus RS485 or BacNet MS-TP (configured with use of HMI).

When configured as a “Slave” the RS485-1 connector is used to connect with the RS485-2

connector of the “Master” device.



The controller is equipped with 5 digital line-ins marked (D1…D5), connecting an input signal of

24VAC/DC switches the input on. Each of those lines can have one of the functions listed below. The

configuration is to be performed with use of HMI controller – “Service menu/Input functions”.

Function Description

Inactive The line is not used

Window

If a 24VAC/DC signal is not given to the digital line-in this means a

window is open and the fan and the FCU and chilled beam valves

halted.

Remote stop If a 24VAC/DC signal is not given to the digital line-in the work mode of

the fan and FCU valves is locked

ECO 24VAC/DC signal given to the digital line-in switches the ECO mode on,

lowering the preset work temperature for FCU

Vent 24VAC/DC signal given to the digital line-in switches the temporary

ventilation (fan speed and time to be set in settings menu) for FCU

Filter

24VAC/DC signal given to the digital line-in displays the FCU filter full

alarm (this alarm can be displayed after exceeding the maximum

operation time for fan)

Compress If a 24VAC/DC signal is not given to the digital line-in within 30 seconds

after the fan starts it displays the error of lack of FCU compression

Light Single 24VAC/DC signal given to the digital line-in switches the state of

the line-out controlling the lighting

Blind Single 24VAC/DC signal given to the digital line-in causes a 1s pulse to

be passed by the line out to the blind controller

Dew If a 24VAC/DC signal is not given to the digital line-in it means that the

chilled beam exceeded the dew point



The controller is equipped with five relay line outs (PK1…PK5) and two on/off 24VDC digital outputs

marked as PWM1, PWM2. These are switched as per controller algorithm. Each of those line outs may

have one of the functions listed below. The configuration is to be performed with use of HMI controller

– “Service menu/Output functions”

The controller is equipped with five input lines for PT1000 resistance sensors marked (P1…P5),

configuration of functions of those lines is to be performed with “Main menu/settings”. The following

functions of sensor line-ins are available for choice:

- main sensor of the FCU

- main sensor of the chilled beam,

- main sensor of the floor heating

- temperature sensor of the feed or return water of the FCU

- temperature sensor of the feed or return water of the chilled beam,

- temperature sensor of the feed or return water of the floor heating.

The controller is equipped with one analog 0-10VDC input marked Ain1, that as of now has no

functions attached.

The controller is equipped with four analog 0-10VDC outputs marked (Aout1…Aout4). Control of the

output as per the algorithm of the controller.

connect wiring as per diagram, guidelines of this manual and the desired input/output scheme

of the contractor,

connect the electricity to the HMI controller,

check the correctness of connection of sensors and executing elements (actuators, etc.),

power up the controller,

with use of the HMI panel choose the function of the controller:

“Master” – main controller, other controllers, BMS (if present), sensors, actuators, fans and

other in/out functions chosen for startup are to be connected to it, as set in Service menu/Input

and output functions,

“Slave” – the controller widens the group of devices with additional FCUs (the FCUs of the

respective group work in parallel mode),

check the correctness of readouts and location of sensors,

check the operation of actuators, always check the free travel, full opening and full closing of

actuators,

check if there are no alarms, remove any,

start the system,

check again for alarms, remove any alarms.

Independent from the factory settings of the controller check the correctness of system

temperature calibration.

Choose temperature settings in such a way, that the system adjusts itself as fast as possible

without oversteering (in order to slow down the system reaction lower the Kp parameter value or/and

increase the Ti parameter value)



9.1 4-FUN controller as a MASTER


Main controller

- type of controller set to

“MASTER” in service

menu

The “4-FUN” controller is design to control

the room comfort through:

- control of a 2 or 4-pipe FCU,

- control of chilled beam,

- control of floor heating,

- control of lighting,

- control of blinds.

These functions are activated automatically,

after activation of respective input/output

functions in service menu.

Controller power supply voltage is 230VAC, recommended cable type 3x1.5mm2, the power line is to

be protected with use of B10 overcurrent circuit breaker.

The HMI panel is to be connected with a shielded-shielded twisted pair cable (that is every pair of

twisted wire is shielded, and the whole is shielded again) of the S-STP or BUS O2YS(St)CY

1x2x0.64/2.6mm type. It is important for the communication signals A,B to be sent through pair of

twisted wires.

Connection of PT1000 sensors – LIYCY shielded cable (in case of variation of sensor readouts connect

the shielding to the “G” connector).



Signals of the digital inputs with LIYY line type of cable.

Connection of 3 speed FCU motor (230VAC), actuators (24VAC, 0-10VDC) and Y1-heating, Y2-cooling

valves.



Connection of actuators (24VAC, on-off) of Y1- heating, Y2 – cooling valves.

Connection of actuators (230VAC, on-off) of Y1- heating, Y2 – cooling valves.



Communication connection of MASTER controllers with the BMS and communication connections

between MASTER and SLAVE controllers (optional ETH adapter can be used for communication with

BMS).

9.2 4-FUN controller as a SLAVE




Widening a group of

parallel-controlled FCUs

- setting the controller

as a “SLAVE” in service

menu

- connection of Master

and Slave controllers as

per diagram

- setting the Modbus

communication

parameters of the SLAVE

controller

- setting the Modbus

addresses in the SLAVE

controllers

- activation of set

number of SLAVE

controllers in the menu

of the MASTER controller

Passing the state of digital outputs :

PK1 – 1st fan speed

PK2 – 2nd fan speed

PK3 – 3rd fan speed

PK4 – heating valve

PK5 – cooling valve

and 0-10VDC analog outputs:

Aout1 – heating valve

Aout2 – cooling valve

Aout3 – fan speed

As per the FCU operating algorithm of the

MASTER controller



10. Modbus RTU Communication

The controller is equipped with Modbus RTU protocol implementation. In order to connect network:

- connect the HMI panel to the 4-FUN controller used as “MASTER”

- enter the HMI menu: COMMUNICATION SETTINGS / RS485 MASTER COM SETTINGS and set the BUS

MODE parameter to “Modbus/ELPbus”

- enter the HMI menu: COMMUNICATION SETTINGS / RS485 MASTER COM SETTINGS and set the MAC

ADDRESS to a freely chosen Modbus address (the individual address of that controller)

- connect the RS-485 bus to the RS485-1 port of the controller bar.

Default communication parameters (can be changed with use of a connected HMI panel):

● transmission speed 9600 bps

● 8 bits of frame

● 1 stop bit

● no parity

All variables are 32-bit Holding Register values. Modbus registers are 16-bit that is why each 32-bit

variable occupies 2 16-bit variables. The readout of variables with use of Modbus 0x03 command,

writing 16 bits of single variable with the 0x06 command, many variables with 0x10 command.

Presentation of variables

Table below lists all variables of the control system. Variables have several numerical representations:

Multistate – the total variable values correspond to the described states

Decimal – 32-bit value of variable treated as a total type with character

Fixed – fixed position type in which the 8 least important bits are for the fraction part, the

remaining 24 bits for the absolute numbers. Thus the accuracy of fixed value is 1/256. In order

to scale the Fixed value to the target (actual) value multiply it by 1/256 = 0.00390625.

11. Bacnet MS-TP communication with the BMS system

The BacNet variables are to be searched for after connecting an operating controller and inputting the

correct settings of the BacNet network (see item 2)



12. Website control

The controller is equipped with an option of controlling through a website. The hardware required for that is an optional Ethernet adapter installed in the location marked on the image below:

In order to connect from a local computer connected directly to the ETH adapter with use of a

cable: Set the below listed values of the TCP4 protocol for the network adapter of the computer:

RJ45 connector

ETH adapter



Then run your Internet browser and type in the default controller address: 192.168.0.8

A window will display for you to type in the default login: admin and password: admin

After typing in the login and password, and confirming with a click of “Login” button the HMI

screen of the controller will be displayed and settings and readout of the full controller menu are possible.



The controller has an Ethernet interface, thus in order to connect the controller wirelessly with the local wireless Network (WiFi) and additional router should be used – configure the

local WiFi network as the access point and then plug the controller to the router. The network settings of the router and controller must match. Ports of the controller are to be redirected

to the external address of the router.



Below schemes of different types of connection:

1. Connecting the controller to LAN through WiFi

Router with port redirection: 80. Thus from the controller: 192.168.0.8:80 to the example outside address of the router: 10.10.10.31. This makes the controller visible in the local WiFi network.

When connecting from within the local network direct access through http://10.10.10.31

2. Direct communication of controller through WiFi router

Router with port redirection: 80. Thus from the controller: 192.168.0.8:80 to the example

outside address of the router: 192.168.0.1. This makes the controller visible in the local WiFi network.

When connecting to the dedicated network controller access is granted at: http://192.168.0.8

http://10.10.10.31/

3. Including the controller in the local WiFi Network and making it available from

outside the network

Redirection on the main router from the WiFi router of the controller: port: 80 from IP: 10.10.10.31 to external IP port: 80 IP: 83.100.100.1

Router with port redirection: 80. Thus from the controller: 192.168.0.8:80 to the example outside address of the router: 10.10.10.31. This makes the controller visible in the local WiFi

network. When connecting from any other Internet location the controller can be accessed at http://83.100.100.1



13. Instructions, advice, recommendations

Automated elements to be connected as per diagram and the following instructions:

230VAC power cables of the YLY type,

24VAC,DC control cables for digital on/off signals of the types LIYY, LIYCY no thinner than

0.5mm2,

24VAC,DC control cables for analog 0-10VDC signals or temperature sensors of the LIYCY type,

for communication of the HMI interface use a shielded-shielded twisted pair cable (that is every

pair of twisted wire is shielded, and the whole is shielded again) of the S-STP or BUS

O2YS(St)CY 1x2x0.64/2.6mm type.

BUS O2YS(St)CY 1x2x0.64/2.6mm type cable for communication with the BMS Modbus RS485

or BacNet MS-TP communication,

in no event shall communication cables be placed together with control and power cables,

construct separate cable ducts for communication cables,

the HMI panel is to be installed within 100m of the controller,

in no event twisted pair cables are to be used for control purposes for on/off, 24V, 230V, 0-

10VDC signals.

“Slave” devices are to be connected in the serial topology of the Modbus RS485 network.

“Master” device and the BMS system can be connected in the serial topology of the Modbus RS485 or

BacNet MS-TP networks, or - with use of additional Eth adapters - through a Modbus TCP/IP or BacNet

IP network.

Failure to observe the above recommendations may result in erroneous operation, serious of electric

shock and void the warranty.

WARNING!!! The controller is 230VAC powered, prior to switching on the power supply make

sure the controller is in a casing that prevents touching the controller and secure the

powering cable with use of overcurrent protection, as per applicable standards. Only a

qualified and properly trained technician may perform the actions listed above. Failure to

observe the above recommendations may result in electric shock.

As we constantly develop our devices content of this manual may slightly differ from the actually

available functions and the controller or panel may differ insignificantly from their actual appearance.
