Pump controller ST-20 TECH, designed to control the central heating water circulation pump. The set temperature is determined using a potentiometer. The controller activates the pump when the temperature reaches the set value and deactivates it if the temperature falls 2°C below it. Advantages: Prevents unnecessary operation of the pump, saves electricity, and extends the pump's lifespan.
