Installation staff of the heating system can realize the configuration of the waterway mapping relationship between the temperature control industrial and agricultural equipment and the water collecting and distributing device 1 by configuring the configuration unit 41.
Suppose that the heating system comprises 1 water dividing and collecting device 1, m electric valves 3 and n temperature controllers 22, wherein m and n are positive integers, and n is less than or equal to m. The n temperature controllers 22 are in communication connection with the control circuit board 4 of the water collecting and distributing device 1, and the control circuit board 4 of the water collecting and distributing device 1 is electrically connected with each electric valve 3.
The basic functions of the temperature controller 22 include setting room temperature and detecting actual temperature; the basic functions of the control circuit board 4 of the water collecting and distributing device 1 comprise driving an electric valve 3, wherein the electric valve 3 can be an open-close type or an opening type electric valve 3; the temperature controller 22 can transmit and output the control signal of the electric valve 3 calculated according to the set room temperature and the detected actual temperature in the room through the temperature controller 22 or the control circuit board 4 of the water collecting and distributing device 1.
