The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
The embodiment of the invention provides a kind of controller of air-conditioner, Fig. 1 is the schematic diagram according to the controller of the embodiment of the invention, as shown in Figure 1, the controller of this embodiment comprises air conditioner room unit control mainboard and air-conditioner outdoor unit control mainboard, particularly, the indoor set mainboard can be connected with DRED equipment by RJ45 netting twine socket, and the signal output part of DRED is connected to the voltage sampling circuit of indoor set mainboard, and the signal controlling end of DRED is connected with the 12V power supply of indoor set mainboard; The indoor set mainboard is connected connection and carries out communication connection respectively and be electrically connected with electric lead with the off-premises station mainboard.Wherein, DRED equipment is connected as shown in Figure 2 with the indoor set mainboard interface, the DRED device interior by 3 relays form, the light current of relay+12V control signal takes from indoor set mainboard+12V power supply, further, DRED equipment is connected to the DRED mode signal sample circuit of indoor set mainboard by the indoor set mainboard interface, the physical circuit figure of sample circuit as shown in Figure 3, the action principle of each device is listed below in the circuit:
