Abstract: A method for processing signals received by a wireless controlled circuit of a steam device, includes the steps of: judging a received signal is a registration signal or a control signal; if the received signal is a registration signal, storing an ID code contained in the registration signal; and if the received signal is a control signal, judging whether the control signal contains an ID code same as a stored ID code or not, then responding a control instruction contained in the control signal if yes, and not responding the control instruction contained in the control signal if no. The present invention has the following advantages: when a plurality of the steam devices are placed together, each wireless controlled circuit of the steam devices will only respond the special remote controller which is registered correspondingly and not respond a non-corresponding remote controller.
