ST-19 controller for central heating pump

Controllers for central heating pumps with anti-stop function

The presented regulator ST-19 with anti-stop function is intended for controlling the central heating water circuit pump. The desired temperature is set using a potentiometer. The task of the regulator is: to switch the pump on if the temperature reaches the preset value and off if the cooker cools down by 2°C below the preset 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.

The St-19 controller also has an additional anti-stop function, which prevents the circulation pump from stagnating during the off-season (the pump switches on every approx. 10 days for 1 minute).
