eUNI3 Weather-based controller for heating ■ control of three central heating (CH) circuits with mixing valves (e.g. radiator and floor heating systems] ■ independent setting of temperature and weather curve for each circuit ■ independent control of each circuit with room thermostat and weekly schedule ■ controls both: main heat source - with its own controller, e.g. gas-fired boiler, and additional heat source -manually operated, e.g. solid fuel boiler, fireplace ■ manual or automatic switching of summer / winter season - possible setting of starting and ending dates of the heating period ■ selection of the circuit operating mode: by turning the pump on and off or by decreasing the temperature with a mixing valve with the pump turned on permanently ■ utilizing the heat generated in the additional heat source (fireplace, solid fuel boiler] ■ output for boiler or additional heating device control ■ communication - possibility to combine several UNI3 and UNI2 controllers in order to operate extended systems ■ possibility to turn off the mixing valve control or to turn off the circuit completely ■ Anti-Stop function - protection of pumps and valves against seizure ■ records of hazardous and alarm events ■ overheating protection for each circuit ■ alarm of allowable temperature excess ■ possibility to turn on the frost protection mode ■ cooperation with floor heating distributors ■ controller interface languages: Polish, English, German, Czech, Russian and Hungarian ■ set of sensors included Controlled device Supply voltage Maximum power consumption Maximum load of outputs Controller outputs Temperature measurement range Temperature control range Temperature control accuracy Temperature reading accuracy Visual signalization Operating temperature Storage temperature Ingress protection rating Color three central heating circuits with pumps and mixing valves 230 V 50 Hz 4 W 100 W (each output) relay, voltage type for pumps, valve actuators and alarm outputs relay, voltage-free type for control of the boiler or other heating device -30°C... +110°C +15°C...+90°C 1°C 1°C backlit LCD, RGB LED +5°C...+40°C 0°C...+45°C IP20 gray, RAL7035 P.H.P.U.
