Send commands through the X-10 modules (such as the 2 Prong Appliance Module) placed throughout your home, as the X-10 communicates between transmitters and receivers by receiving and dispatching signals over your home's existing electrical wiring.

The Mini Relax with X-10 or the Relax II will then send radio frequency signals to the X-10 Transceiver, which in turn sends commands to the X-10 modules.

Please note that separate X-10 modules are required for each appliance you need to control.
