Controllers for CH Pumps

Controller Description

The EU-427i regulator is intended to control the operation of three pumps. The regulator’s task is to switch the pumps on if the temperature exceeds the threshold activation value, as well as to switch them off when the boiler cools down (due to damping). For the second pump, apart from the activation temperature, the user adjusts the set temperature to which the pump will operate. It is possible to adjust any priorities of the pump’s operation.

Functions Performed by the Controller:

  • Control of three pumps on the basis of temperature measurement or temporarily

  • Anti-stop function

  • Anti-freeze function

  • The possibility to set any pump priorities

  • The possibility to connect a room regulator

Controller’s Equipment:

  • LCD display

  • Three temperature sensors

  • Pulsator knob

  • A casing made from high-quality materials resistant to high and low temperatures
