EU-20

Controllers for CH Pumps

Principle of Operation

The EU-20 regulator is intended to control the CH water circulation pump. The potentiometer is used to adjust the set temperature. The regulator’s task is to: switch on the pump if the temperature reaches the set value, and to switch it off if the furnace cools down 2°C below the set value. Such an operation mode prevents the unnecessary operation of the pump which makes it possible to save electricity and extends the pump’s life as well as improves its reliability.

Functions Performed by the Controller:

• CH pump control

Controller’s Equipment:

• CH temperature sensor

• Potentiometer to adjust the set temperature
