Tech ST-20 temperature controller for central heating pump

Temperature controller The Tech ST- 20 is designed to control the circulation pump. Its function is to turn it on when the temperature exceeds the required value and to turn it off when the boiler cools down (due to extinguishing). This prevents the pump from running idle, resulting in energy savings (depending on boiler utilization, savings can reach up to 60%) and extending the pump's service life.
