Abstract: A room device comprising two or more connectors (2a, 2b, 15) for providing building power to the room device (1); a device controller (3a) configured to operate a heating, ventilation and/or air-conditioning system (4); a device memory (3b) in operative communication with the device controller (3a); wherein the device memory (3b) and the device controller (3a) require building power for standard operation; a transponder controller (5a) and an antenna (5c); a transponder memory (5b) being powerable by the transponder controller (5a); a device firmware stored in the device memory (3b), the device firmware including instructions causing the device controller (3a) upon providing building power to the room device (1) to: connect to the transponder controller (5a) such that the device controller (3a) is in operative communication with the transponder controller (5a); transfer the initial configuration data stored in the transponder memory (5b) to the device memory (3b).

Abstract: Various embodiments include a device comprising: two connectors for powering the device; a controller to operate an HVAC system; a memory; a transponder controller and an antenna for near field communication; and a transponder memory storing a configuration version and an address list. Firmware in the transponder memory includes instructions for the controller to: connect to a handheld device; determine an address thereof; determine whether the address is on the list; if so: receive initial configuration data from the handheld device, and store it in the transponder memory. There is firmware in the device memory telling it to: connect to the transponder controller; read a device version; read the configuration version in the transponder memory; determine whether the configuration version is compatible with the device version; and if so, transfer the initial configuration data to the memory, and thereafter use the initial configuration data in operation of the system.
