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

immediately, operation with a clogged filter lowers the fan
efficiency and may cause it’s mechanical tearing, which may
lead to damage of heat/cold exchangers that will be culpable to
the customer
Testing filter condition with use of filter operation time:
Normal state – the filter in acceptable condition, time limit is
not exceeded
Alarm state – inacceptable contamination, time limit for system
operation exceeded
Reaction to alarm: the system works on, clogged filter alarm

9. Startup
In order to start the system for the first time one should:
read this manual carefully,
install the controller in its housing,
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
Function Condition for work Description of operation
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).

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.

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.
Oleśnica 2016-02-18
43/45 DTR-4-FUN-AP1-EN-V1
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

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.
