The device is designed to control motor actuators of mixed valves, in accordance with the water temperature directed to the heating system. It can be used also to keep the temperature in buffers or water tanks heated by a boiler by means of a mixed valve.


Technical data:
  • The heating water assignation is able to be adjusted in one of the following ways: independently (manually by the controller), by means of outdoor temperature or room thermo regulator
  • Suitable room thermo regulator are contatct or analogue ones, as the analogue output can be 0(4) – 20 mA or 0 – 10V
  • Suitable motor actuators are two way or proportional ones with a control signal of 0 – 10V
  • The following limitations are to be fixed concerning the heating water:
    • Minimum temperature;
    • Maximum temperature;
    • Minimum return water temperature
  • Pump operation:
    • if the heating water is within the fixed range for the minimum and maximum temperature
    • operation by force in case the heating water temperature is less than 10 °С
    • provide an overheating function of the circuit in case the heating water temperature exceeds its assigned level with 10 °С
    • stops the circulation pump in case the temperature of the heating water is less than its minimum assigned level for period of 1 hour. After that the controller goes into test mode in which it starts the circulation pump for 5 minutes every 15 minutes. This mode continues until the heating water exceeds the assignation about its minimum temperature.
  • Equipped with three temperature sensors Pt-1000.
  • Warranty terms: 24months
