1. A room device comprising:
two connectors for providing building power to the room device;
a device controller to operate a heating, ventilation, and/or air-conditioning system;
a device memory connected to the device controller;
wherein both the device memory and the device controller use building power for standard operation; and
a transponder controller, an antenna for near field communication, a transponder switch connected to the transponder controller, and a transponder memory in communication with the transponder controller, the transponder memory storing a configuration version;
wherein the transponder controller is powered by the antenna and the transponder switch moves between an enabled position and a disabled position;
a transponder firmware stored in the transponder memory, the transponder firmware including instructions for the transponder controller upon powerup from the antenna and before the device is connected to building power to:
read a first position signal from the transponder switch;
produce a first position value from the first position signal;
if the first position value indicates that the transponder switch is in its enabled position, connect to a handheld device, produce a signal indicative of the configuration version, transmit the signal to the handheld device, after transmitting of the signal, receive initial configuration data from the handheld device, and store the initial configuration data in the transponder memory;
a device firmware stored in the device memory including instructions causing the device controller in response to connection of building power to the room device to:
connect to the transponder controller;
read a device version stored in the device memory;
read the configuration version stored in the transponder memory;
determine whether the configuration version is compatible with the device version; and
if the configuration version is compatible with the device version, transfer the initial configuration data stored in the transponder memory to the device memory, and thereafter use the initial configuration data in operation of the system.
