EU-27i

The EU-27i regulator is intended to control the operation of the CH circulation pump as well as an additional pump (DHW or floor). The regulator’s task is to switch the CH pump on if the temperature exceeds the threshold activation value and to switch the pump off when the boiler cools down (as a result of damping).

Controllers for CH Pumps

Principle of Operation

The EU-27i regulator is intended to control the operation of the CH circulation pump as well as an additional pump (DHW or floor). The regulator’s task is to switch the CH pump on if the temperature exceeds the threshold activation value and to switch the pump off when the boiler cools down (as a result of damping). For the second pump, apart from the activation temperature, the user adjusts the set temperature to which the pump will operate.

Functions Performed by the Controller:

  • CH pump control

  • Control of an additional DHW or floor pump

  • Anti-stop function

  • Anti-freeze function

Controller’s Equipment:

  • LCD display

  • CH temperature sensor

  • Temperature sensor of the additional pump

  • Pulsator knob

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