Switching actuator for heating systems – 2 channels

Energy-saving heat supply, regulated the smart way.  

A lovely start to the day begins with a warm shower. If only the permanent hot water supply didn't cost so much running water or energy through the circulation pump. To ensure that the hot water circulation in the house only runs when it is needed, install the switching actuator for heating systems. That's how you save water and energy. You also benefit from the actuator's other functions!
