Euroster UNI3 - programmable controller for 3 heating circuits

Product detailed description

• possibility of independent setting of temperature and weather curve for each circuit
• enables independent control of each circuit together with a room thermostat and a weekly schedule
• controls - main heat source with its own controller e.g. gas boiler and auxiliary heat source - manually operated - e.g. solid fuel boiler, stove
• manual or automatic switching of summer / winter season - possibility to set the start and end date of the heating period
• selection of operating mode of the circuit by switching on and off the pump, or by reducing the temperature via a mixing valve with a permanently switched on pump
• utilization of heat generated in the auxiliary heat source (stove, solid fuel boiler)
• output for boiler, or control of auxiliary heating device
• communication - possibility of combining several UNI3 and UNI2 control units for the purpose of controlling auxiliary systems
• possibility to switch off the control of the mixing valve, or to completely switch off the circuit
• anti-stop function - protection of pumps and valves against short-circuit
• records of dangerous and alarm events
• overheat protection for each circuit
• signal at each exceedance of the permitted temperature
• possibility to activate the anti-freeze function
• cooperation with underfloor heating distributors
• interface languages of the controller: Czech, English, German, Polish, Russian, Hungarian
