5, EUROSTER UNI2 EUROSTER UNI2 – INSTRUCTION MANUAL 5 controller. Settings for CH1 heating circuit and identical ones for CH2 circuit  turning the circuit on/off This item enables to turn off the unused circuit.  Mixer  turning the mixer on/off This option enables to turn the mixer control off if it is not used in the CH circuit. In such case the (current and preset) temperatures are not displayed for the particular circuit. When operating with turned off mixer the functions responsible for controlling the temperature and the continuous operation f…

6, EUROSTER UNI2 EUROSTER UNI2 – INSTRUCTION MANUAL 6  frost protection, anti-frost temperature The anti-frost algorithm is activated when the temperature of the particular circuit sensor drops below the preset level. In such case both the boiler and the pump are activated. The schedule settings do not affect the operation of this protection. CAUTION! The protection is disabled by default.  sensor correction CH1 or CH2 circuit sensor correction allows to correct temperature reading errors, such as the ones resulting from improper contact between the…

7, EUROSTER UNI2 – INSTRUCTION MANUAL 7 Settings for DHW circulation circuit  turning the circuit on/off This item enables to switch off the circulation circuit if it is not used.  Control  temperature-based control of circulation Circulation may operate according to time or temperature parameters. In case of temperature-based control, the circulation pump is running until the temperature of the circulation t…

Incorrect installation and improper use may lead to a serious hazard to a user or other persons and result in material damage! Prior to mounting or dismantling and maintenance of the controller, make sure that it is de-energized!  Dangerous voltages, hazardous to life, may be present on the controller and its cables, ther…

10, EUROSTER UNI2 – INSTRUCTION MANUAL 10 The connection diagram is shown below. 4.2.Maintenance Before each and every heating season, the controller must be cleaned of any dust and dirt, the cables must be checked for tight fixing. If necessary, wipe it carefully with a soft cloth. Do not use solvents and aggressive detergents since they may damage the surface of the housing and the display. Avoid contact with water or other liquids. 4.3. Communication 4.3.1. RS-485 connection UNI2 con…

11, EUROSTER UNI2 – INSTRUCTION MANUAL 11 4.3.2. Address allocation After connecting a twisted pair, activate the communication and select the addresses of controllers in all connected controllers. Each of the controllers must be provided with a different address. It is advised to write down the addresses in a visible place in a boiler room, which will facilitate the configuration process. 4.3.3. Boiler control The communication feature enables to control the boiler with the use of one controller output. T…
