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.
Page 6: Installation
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: •...

6. To power the regulator, use a cable the parameters of which are the same or higher than those for the cable insulated with 600V vinyl with a cross-section of 1 mm2 or bigger. 7. Tighten the terminal screws to a torque of 1.0 Nm. 8.
Page 8: Disposing Used Equipment
• All connections must be compatible with the electrical wiring diagram and national or local electrical requirements. • This unit does not contain parts that can be replaced by the user. All service operations except for cleaning, fuse replacement (when disconnected) and function setting should be made by qualified service personnel.
Page 9: Description Of 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.

Advanced Fuel selection The WOOD option is recommended only for boilers with an additional grate when burning wood. In this option, the burner does not work. Only the fan is used which works in a comparable manner to wood-fired boilers. The PELLET option activates all the functions of the regulator and the burner.
Page 23: Burner
ECO mode The ECO mode is recommended during summer. In this option, the burner is turned off when the boiler is heated up and the boiler temperature can decrease to any value (the anti-freeze function is still active). For the ECO mode turned off, the regulator always tries to maintain a minimum temperature in the boiler.
Page 24 must be set to completely ignite this amount of fuel. A too long ignition time will burn the whole amount of fuel and the flame will go out. Burning During the burning phase, the burner can be operated in two modes: with a variable output regulation called PID control, and two-stage control (PID disabled).
Page 25 Output selection The "Output selection" menu is available only for the PID option enabled (see PID). This parameter helps to set the burner operation parameters for each output (minimum, average and maximum). It is possible to choose a particular burner output by selecting one of the following options: •...

fan changes the output to the value fixed in the "Stopping" submenu. After the set time runs out, the fan switches on the maximum output for 1 minute and cleanses the burner of ashes. Fuel burn up time Set an appropriately long time to burn up the heat in the burner. Fan output During the stopping process, the airflow should be small so as not to throw the burned pellet to the ash bin.
Page 27 For underfloor heating it is good to set number 3, for radiator heating - number 7. The full range of characteristics offered by MULTIFUN is presented further. The AUTO operation mode is possible only for configurations with the external sensor. For simple options, the AUTO mode is not displayed.
Page 28 Note: A change in the room temperature (Temperatures/Heating temperature menu) has influence on the weather characteristics that adapts to new requirements. Room sensor - adjustment The controller will automatically correct the heating temperature after detecting differences between the room temperature set value and the sensor reading. The adjustment allows increasing the influence of the sensor on the CH temperature changes (values greater than zero) or decreasing it (negative values).
Page 29: Hw Circuit
HW CIRCUIT HW temperature Setting the HW dispenser temperature is possible in the range from 15 up to 60 C. Moreover, this parameter is accessed from the level of TEMEPRATURES menu and ADVANCED/HW circuit. When the dispenser temperature is lower than the set value by HW hysteresis, the regulator will initiate the dispenser load process. When the temperature is higher than the set temperature plus HW hysteresis, the loading process is completed.
Page 30 Description of activities Select the program number for a chosen day of the week. The user can choose from three default presets and edit two programs. The black bar indicates the time to maintain the desired temperature in the HW dispenser - the HW pump and the circulating pump are operating.
Page 31: Clock
Program no. 5 Operation and service is analogical to Program no. 4. Legionella(ON/OFF) Activation of this function aims at destroying Legionella (bacteria) in the HW dispenser. The process is carried out by heating the dispenser up to 70°C and maintaining this temperature for 2 hours. This function starts automatically every Monday at 1:00 AM.

The regulator is equipped with an SD card slot. In this option it reads basic information about the card: the amount of free space and total card capacity. Note: We are not responsible for any data loss on your memory card. We do not guarantee that the regulator will work with all memory card models on the market.

buffer. Connecting the sensor to the regulator when we turn on the buffer pump and the installation is made based on Figure 4. Hydraulic installation diagram with a heat buffer does not affect the operation of the equipment. However, it is possible to read the measured return temperature. Boiler type Boiler model selection sets the parameter ranges and the default settings in an optimal way for the product.
Page 34: Circuit Control
For the underfloor installation, a value that is safe for this type of heating should be set, usually 55C. The valve will close when the installation reaches the set temperature and when it continues to grow the regulator will switch off the CH pump. For radiator heating, a maximum value needs to be set, i.e. 96C. For this setting, the emergency valve will discharge the heat into the installation and the CH pump will not be blocked in the installation protection function.

1. It is required to connect a room thermostat with a closing contact (e.g. AURATRON). The thermostat should close the measuring line - room sensor input, for the temperature decrease time. NO VOLTAGE MUST BE CONNECTED TO THE REGUALTOR'S MEASURING INPUT.
Page 36: Hw Rundown During Summer
The user needs to set a time for the pump to allow it to pump water through the piping system, so that after turning on the tap hot water appears. Downtime The downtime should be as long as possible, but the water in the pipes cannot cool down too much. The user should not feel uncomfortable when using HW.
Page 37: Operation Modes
1. Lower temperature can be automatically reduced when the calculated value is too high. In this case, the regulator will accept a value (maximum temperature - 5°C) as the lower temperature. 2. If the automatic upper temperature is turned on, the lower temperature principle is set as follows: Tlower_automatic = Tupper_automatic + (Tlower - Tupper) Operation modes The buffer can be loaded only based on buffer sensors temperature, so-called continuous loading.
