WATER PUMP REGULATOR CONTROLLER CO ST-20 TECH

The ST-20 regulator is designed to control the central heating water circulation pump. Setting the set temperature is done using a potentiometer.

Principle

The ST-20 regulator is designed to control the central heating water circulation pump. Setting the set temperature is done using a potentiometer. The task of the controller is: switching on the pump if the temperature reaches a set value, and turning it off – if the furnace cools down by 2°C below the set value. This mode of operation prevents unnecessary operation of the pump, which saves electricity and prolongs the life of the pump and increases its reliability.

Functions performed by the controller:

• CH pump control

Controller equipment:

• CO temperature sensor
• potentiometer for setting the set temperature
