The TZ65S Wall Switch Dimmer i s a component of the lighting control system. This wall mounted dimmer is designed to work with other Z-Wave enabled devices. Z-Wave nodes of other types can be added to the system and will also act as repeaters if they support this function of repeating the signal received to other modules in the system. As part of a Z-Wave network, the TZ65S will also act as a wireless repeater to insure that commands intended for another device in the network are received. This is useful when the device would otherwise be out of the radio range of the wireless controller.
