Model SFCY -Split Non-Pressurized Solar Water Heaters

When the temperature of the heat collector reaches the set value, the controller shall start the circulation pump auto- matically. The circulation pump makes heat-conducting liquid circu- late automatically. The heat-conducting liquid transfers heat to water by the heat exchanger in the water tank. In case the temperature of the collector does not reach the set value, the circulation pump shall be shut automatically. In case the temperature of the water tank does not reach T-max, then start the auxiliary heating device.
