Split networked intelligent temperature controller of central air conditioner

The invention discloses a split networked intelligent temperature controller of a central air conditioner. The temperature controller comprises a control panel and a power supply board which are connected; the control panel comprises a temperature measurement module, a liquid crystal display module and a parameter setting module; and the power supply board comprises a power supply module, a relaycontrol module and an RS485 interface circuit, wherein the power supply module supplies power to the relay control module and the control panel. A single micro control unit (MCU) structure is adoptedin the temperature controller, and the front panel and the rear panel are split in the design; and by adopting the single MCU, the defect that a wiring tube of the traditional temperature controller is not easily connected to centralized (remote) monitoring of the central air conditioner is overcome, the dependency of civil engineering is reduced, the use safety is promoted, the universal applicability of any standard junction box is enhanced, and the networked expansibility of the system is exploited.
