Title:
TEMPERATURE CONTROLLER AND HEATING, VENTILATION AND AIR CONDITIONING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/021380
Kind Code:
A1
Abstract:
A temperature controller, comprising a housing (10), a display screen (20), a capacitive proximity sensor and a processor unit (40). The housing (10) is provided with an operation panel (12), and the display screen (20) is arranged in the operation panel (12). The capacitive proximity sensor comprises a detection electrode (30) and a signal conversion circuit (42). The detection electrode (30) is arranged on an inner surface of the operation panel (12), and generates a proximity signal when there is an object approaching the operation panel (12). The signal conversion circuit (42) is arranged in the housing (10) and can convert the proximity signal into a switching signal. The processor unit (40) is connected to the display screen (20), and the processor unit (40) can control a ventilation and air conditioning control system, and the processor unit (40) can, after receiving the switching signal, turn on the display screen (20) so that the display screen carries out display according to preset parameters, and can turn off the display screen (20) after a continuous period of time in which no switching signal is received. The temperature controller can sensitively sense if there is an operation of a person and then automatically turn on a screen.
