Introduction
The following instruction manual was written for all users who will connect, install, operate and conduct routine
maintenance of Multifun control system regulators. The instruction manual includes descriptions of installation,
wiring, functions and operating procedures. It should be kept near the workplace area while operating the
regulator. The information contained therein must be always followed.
Warning
Should any fault occur or accessories are missing, please contact your local dealer or sales office at RECALART
ELECTRONIC.
MULTIFUN CONTROL SYSTEM regulators are designed for mounting in control cabinets or similar installations in
a way that prevents their contact with electrical cable thimbles.
Do not remove the regulator from the housing. Your hand or other conductive body must not be found in the
housing. This could result in a serious injury or death due to electrical shock.
To avoid damage to the connected equipment or the MULTIFUN CONTROL SYSTEM regulators, prior to using the
device take any safety measures necessary, such as installing a fuse, overheat protection device, etc. Should an
accident caused by using the product without observing these safety measures occur, the warranty will be void.
The power switch in the external circuit of the regulator turns off power. The switch needs to be installed on the
device in a position that allows for ease of use. There should be a message that the switch turns off power.
Use a switch which meets IEC947 standards.
The device does not have a built-in fuse therefore a fuse must be installed in the power circuit when connected
to a phase terminal. The fuse should be placed between the power switch and the device and mounted on the
"L" side of the phase terminal.
Fuse rated values/characteristics: 250 VAC 6.3A quick.
Use only a fuse complying with IEC 127 standards.
Voltage/current values of load to connect to the output terminal and the alarm terminal should be placed
within the range of the rated values. Otherwise, the temperature will increase and reduce the regulator's life
causing problems in the operation of the device.
Voltage/current other than specified in the input specifications should not be attached to the input terminal.
This may shorten the instrument's life and cause operation problems. For the voltage or current input, the input
terminal should be connected to a device that meets IEC1010 requirements.
The device may have vent holes to carry off heat. Metal elements or other that can damage the device or cause
fire must not get inside the holes.
The vent hole must not be blocked nor contaminated. A temperature increase or insulation failure may shorten
the instrument's life or damage it. Moreover, these situations may be a direct cause of a fire.
Information about spaces that separate the regulators in the control cabinet in are described in chapter en.
"Internal dimensions and a panel cut-out" of the service documentation.

6
It should be noted that repeated tolerance tests for voltage, disturbance, surge, etc., may deteriorate the
instrument's operation.
Changes made to the device or its improper use is prohibited.
INSTALLATION
The regulator should not be used in the following places:
• In environments including flammable gas, corrosive gas, oil mist or particles that can deteriorate the electrical
insulation.
• In an atmosphere at a temperature below 0°C or above 55°C and relative humidity above 90%RH or below the
dew point.
•In an environment with high vibration or shock levels.
• In locations exposed to high electromagnetic interference.
• In areas exposed to direct sunlight.
• In an environment at a height of over 2000 meters above sea level
• Outdoors.
The aforementioned places can cause malfunctions, fire or damage to the device.

Description of the device
The Multifun control system regulator is a modern multiprocessor control system for heating
devices. The basic version of the system consists of a control panel and a main run-time
module. These devices are connected via a LAN cable and an RJ45 type connector. Additional
modules can also be connected using this cable. Data transfer is carried out in RS485
standard. A modified MODBUS protocol ensures a correct data exchange.
The main run-time module
For the basic operation of the device, boiler sensors need to be connected to the run-
time module without which the boiler will not work properly:
• Boiler feed temperature sensor [BOILER FEED]
• Feeder temperature sensor [FEEDER]
• Flame sensor [PHOTODETECTOR]
To successfully run other functions of the controller, appropriate sensors must be connected
to the run-time module:
• Fan hall generator* - recommended when using a fan with a revolution number sensor.
• Hot water temperature sensor [HW] - when water heating.
• Central Heating temperature sensor [CH] - to control the mixing valve
• Return temperature sensor of the heating medium [Boiler Return] - protection against cold
water returning to the boiler. The sensor is necessary to work with the mixing valve or the
circulating pump
• External temperature sensor [External] - required if the weather function is active
• Room 1 temperature sensor [Room1] -

days. By using the menu visible on the right-hand side of the screen, it is possible to hide unnecessary charts.
This increases legibility of information on the screen. After selecting the data range, the controller calculates the
average value for the data. It is possible to compare two different time periods (e.g. boiler room operation on a
Monday and on a Tuesday) to analyze the influence of control settings on fuel consumption. The controller
shows total fuel consumption in a given period and average burning per hour. Moreover, data (work history)
can be saved to an SD card and analyzed on a PC.
SUMMER/WINTER modes
Select the operating mode. This option chooses the operating mode though it is possible to choose the AUTO
mode (more on SUMMER/WINTER/AUTO).
Manual mode
The manual control mode is used to check devices and sensors connected to the regulator.
Manual control
This allows forcing operation of particular devices. The knob is used to select a device. The operation state of a
device is made by pressing the knob. The knob can be also used to set fan power.
The v31.09 software version (and higher) include information about the number of revolutions per minute if the
Hall generator is working and connected. This information is shown on the rpm symbol. Sample screens:
