The main function of the Hand-Held Controller is to transmit user commands to the PE653 Receiving Device, PE650 Receiving Device, and/or Z-Wave home control devices, and to display the status of the installed equipment.

The unit floats if thrown in the pool or spa, is water-submersible, shock resistant, and requires three (3) AA batteries. Expected battery life is about one year in typical use.

When the components of a specific system are linked together into a network, unique network ID codes supplied by the PE953 prevent unauthorized use of the system by neighboring systems.
