VENT CONTROLLING APPARATUS

摘要

A vent controlling apparatus 10 comprising an actuator 14, 18 adapted to open and close a vent, means for converting energy 16, such as solar power or wind power, to provide power for the actuator, and control means operative to control the actuator in response to a wirelessly transmitted control signal. The actuator may be a chain actuator wherein the chain can only flex in one direction such that it does not buckle. The converting energy may be a solar panel or photovoltaic cell pivotally or detachably mounted for optimum positioning. Wireless transmission by a remote transmitter (51) of one or more control signals may be used to remotely control the operation of the actuator to open or close a vent. A remote transmitter may be adapted to transmit an open or close command without user input to thereby automate the opening and closing operation. Automated operation of the vent may be dependent upon an environmental condition. The device may have a standby mode in which the control means operates in a reduced power mode.
