Split Pressurized System

When the temperature of the heat collector reaches the set value , the controller shall start the circulation pump automatically. The circulation  pump  makes  heat-conducting  liquid  circulate automatically. The heat—conducting liquid transfers heat to water by the heat exchanger in the water tank. In case the temperature of the circulation pump does not reach the set value. the circulation pump shall be working automatically. In case the temperature of the water tank does not reach Tmax .then start then electrical heater.
