Abstract

The invention is directed to a low power infrared receiver system capable of battery operation for controling and operating a module, such as a gas fireplace valve. The system includes in one form a universal remote type infrared transmitter for transmitting an infrared signal and an infrared receiver. The receiver includes an infrared detector for receiving an infrared signal from the remote infrared transmitter, a microprocessor connected to the infrared receiver to receive and process a signal to determine if the received signal corresponds to a predetermined signal, and a power switch connected to the microprocessor and the module so that when the microprocessor determines that the processed received signal corresponds to a predetermined signal the power switch is activated thereby operating or controlling functions of a gas fireplace or other appliance via the associated module.
