Euroster UNI3
Euroster UNI3
Weather-compensated control unit for independent control of heating systems with 2 heat sources and 3 heating circuits with mixing valves. Equipped with anti stop pump protection system.

Euroster UNI3 is a universal weather controller for independent control of heating installations with 2 heat sources and 3 heating circuits with mixing valves (e.g. radiator and floor heating). Advanced control algorithms ensure trouble-free operation of the installation, and the graphic display and multifunction knob - intuitive and friendly operation of the controller. Euroster UNI3 has a number of useful functions and an anti-stall anti-stop pump system that prevents seizing of the unused pump impeller. After the end of the heating season, the system automatically starts the pump every two weeks for 30 seconds (for the system to work after the season, the controller should be left turned on).

Benefits
  • Control of three heating circuits with mixing valves (e.g. radiator and floor heating)
  • Independent setting of temperature and weather curve for each circuit
  • Independent control of each circuit with a room regulator and a weekly schedule
  • Supports a basic heat source - with its own controller (e.g. gas boiler) and an additional - manually started (e.g. solid fuel boiler)
  • Manual or automatic changeover of summer-winter seasons - the option of setting start and end dates for the heating season
  • Choice of circuit operation method: by switching the pump on and off or by lowering the temperature with a mixer when the pump is always on
  • The use of heat generated in an additional heat source (fireplace, solid-fuel furnace)
  • Output to control the boiler or additional heating device
  • Communication - the ability to combine several UNI3 and UNI2 controllers to support extensive installations
  • Possibility to turn off mixer control or turn off the circuit completely
  • Anti-Stop function - protection of pumps and valves against stagnation
  • Register of dangerous and alarm events
  • Protection against overheating of each circuit
  • Alarm for exceeding the permissible temperature
  • Possibility of activating the anti-freezing mode
  • Cooperation with floor heating distributors
  • Controller support in Polish, English, German, Czech, Russian and Hungarian
  • A set of sensors included
