Abstract
The utility model relates to a temperature controller for a solar water heater, in particular to a solar intelligent thermal controller which combines solar energy heating and electrical heating, achieves the automatic switch therebetween and effectively prevents insufficient and excess electrical heating. The solar intelligent thermal controller consists of a PLC controller, a solar collector, a heat storage water tank and a circulating water pump; when the thermal controller is in use, the solar collector starts to work after being filled with water; the PLC controller collects water temperature signals in the solar collector and the heat storage water tank through temperature sensors respectively mounted therein; and the temperature value is converted into voltage value through signal conversion and compared in a control circuit. When the temperature difference of the solar collector and the heat storage water tank reaches the preset value, the circulating water pump is started to lead hot water into the heat storage water tank, and cold water enters the solar collector; and when the temperature difference is smaller than the given value, the start signal of the controller disappears, and the circulating water pump stops working.
