ABSTRACT:
A spa system including a remote control for controlling operation thereof. The system includes a remote control module having a microprocessor and memory therefor, which is receptive to push-button inputs. The remote control has a display and an antenna for transmitting signals to the spa and for receiving signals back from the spa. A master control module resides within the spa for controlling and sensing a multiplicity of functions of the spa. A slave control module is coupled to the master control module and also has an antenna responsive to command signals received from the remote control, and for transmitting status signals back to the remote control. The slave control module is used for converting the command signals received from the remote control for the master control, and for converting status signals received from the master control for transmission back to the remote control.
