Central air conditioning fan coil controller

The invention relates to a central air conditioning fan coil control technology, in particular to a wireless communication-based central air conditioning fan coil controller. The controller comprises five parts, namely a control module, a sensor module, a key module, a liquid crystal display module and a control output module, wherein a control program is stored in the control module for running a control strategy and the control module is communicated with an upper computer through a network controller; the sensor module acquires ambient temperature information; the key module receives a key operating instruction of a user; the liquid crystal display module displays a running state, a running mode and ambient environment of the central air conditioning fan coil controller; and the control output module is used for controlling the running of a central air conditioning fan coil. The central air conditioning fan coil controller is applicable to energy-saving reconstruction of a large-sized building; the central air conditioning fan coil can be adjusted according to the ambient temperature to reduce running energy consumption of an air conditioning system; and since a wireless communication technology is adopted, a large amount of wiring can be saved to reduce the manufacturing cost of the system.
