Specifically, the conversion device 40 and the mobile terminal 30 may communicate with each other via Wifi (Wireless Fidelity), Bluetooth or ZigBee.
An operating method of this system for controlling the ducted air-conditioning system is illustrated below by taking a smart mobile phone for example.
A control instruction for starting the ducted air-conditioning system 10 is input by a user to the mobile terminal 30, particularly, to a software running in the mobile terminal 30. The mobile terminal 30 transmits the control instruction for starting the ducted air-conditioning system 10 to the conversion device 40. The conversion device 40 receives the control instruction for starting the ducted air-conditioning system 10 and converts the control instruction for starting the ducted air-conditioning system 10 into a 24V start control instruction, and then transmits the 24V start control instruction to the ducted air-conditioning system 10. The ducted air-conditioning system 10 is started according to the 24V start control instruction and enters an operating state.
FIG. 2 is a block diagram showing the conversion device according to an embodiment of the present disclosure. As shown in FIG. 2, in one embodiment, the conversion device 40 may comprise: a plurality of first wire terminals 410, a plurality of second wire terminals 420, a monitoring module 430, a wireless communication module 440, a transmission module 450 and a control module 460.
Each first wire terminal 410 is connected with one of wire terminals of the ducted air-conditioning system 10, and each second wire terminal 420 is connected with one of wire terminals of the temperature controller 20. The monitoring module 430 is connected with the plurality of second wire terminals 420 and is configured to monitor a state of each second wire terminal 420 so as to receive the first control instruction. The wireless communication module 440 is configured to receive the second control instruction. The transmission module 450 is connected with the plurality of first wire terminals 410 and is configured to transmit the first control instruction or a third control instruction to the ducted air-conditioning system 10.

In one embodiment, the transmission module 450 is further configured to detect a current operating state of the ducted air-conditioning system 10, and the control module 460 is further configured to control the wireless communication module 440 to transmit a detection result (i.e., the current operating state of the ducted air-conditioning system 10) to the mobile terminal 30.
Specifically, the control module 460 controls the transmission module 450 to transmit the first control instruction to the ducted air-conditioning system 10 when the monitoring module 430 receives the first control instruction from the temperature controller 20, and the ducted air-conditioning system 10 adjusts an operating state thereof according to the first control instruction. The control module 460 controls the wireless communication module 440 to transmit a detection result (i.e., the current operating state of the ducted air-conditioning system 10) to the mobile terminal 30, and the current operating state of the ducted air-conditioning system 10 is displayed on an interface of the software running in the mobile terminal 30.
For example, the user sets a temperature of the ducted air-conditioning system 10 to 22° C. via the temperature controller 20. After the temperature of the ducted air-conditioning system 10 is set to 22° C. according to the control instruction from the temperature controller 20, the control module 460 controls the wireless communication module 440 to transmit the current operating state of the ducted air-conditioning system 10 to the mobile terminal 30, and the information that “the ducted air-conditioning system 10 is currently operating at 22° C.” is displayed on the interface of the software. Once the user obtains the current operating state of the ducted air-conditioning system 10, the user may further control the operating state of the ducted air-conditioning system 10 via the software.
In one embodiment, the conversion device 40 may comprise a power supply module (not shown in FIG. 2) configured to convert a supply voltage (such as 24V) supplied by the ducted air-conditioning system 10 into an operating voltage compatible with the conversion device 40.

The C, R terminals of the ducted air-conditioning system 10 supply power to the conversion device 40, and the C, R terminals of the conversion device 40 supply power to the temperature controller 20.
Specifically, if the monitoring module 430 monitors that there are G, Y/W signals transmitted from the temperature controller 20, the control module 460 receives a monitoring result of the G, Y/W signals from the monitoring module 430 and controls the transmission module 450 to transmit a corresponding control instruction to the ducted air-conditioning system 10, and the ducted air-conditioning system 10 performs a corresponding operation according to the control instruction. Specifically, the conversion device 40 may obtain a fan compressor signal transmitted from the temperature controller 20 via the G wire terminal of the conversion device 40, and a compressor assistant electric heat signal transmitted from the temperature controller 20 via the Y/W wire terminal of the conversion device 40.

The method for controlling the ducted air-conditioning system is illustrated below by taking a smart mobile phone for example.
A control instruction for starting the ducted air-conditioning system is input by a user to the mobile terminal, particularly, to a software running in the mobile terminal. The mobile terminal transmits the control instruction for starting the ducted air-conditioning system to the conversion device. The conversion device receives the control instruction for starting the ducted air-conditioning system and converts the control instruction for starting the ducted air-conditioning system into a 24V start control instruction, and then transmits the 24V start control instruction to the ducted air-conditioning system.

For example, the user sets a temperature of the ducted air-conditioning system to 22° C. via the temperature controller.
