1. Heat collection cycle: the heat collection tank and solar water heater carry out heat collection cycle;
2. Backwater control: the constant temperature water tank realizes the backwater circulation according to the difference between the temperature of the return pipe and the temperature of the water tank;
3. Water inlet control: the hot water collection tank is equipped with 5-stage liquid level detection liquid level sensors to realize water inlet control;
4. Water in the constant temperature water tank: The constant temperature water tank is equipped with a 5-stage liquid level detection liquid level sensor, and when there is no high liquid level, water is added.
5. System power distribution: power distribution to 2 external 8KW air energy and 5KW constant pressure water supply pump.
