Abstract: A wall module for use in a building control system includes a wall module controller and a first communications module operatively coupled to the wall module controller for establishing wired communication with a remote building controller, and for receiving instructions and/or data from the remote building controller and for sending instructions and/or data to the remote building controller via the established wired communication. The wall module includes a second communications module operatively coupled to the wall module controller for establishing short range wireless communication having a communication range of less than 60 feet with a portable handheld device, and for receiving instructions from the portable handheld device and for sending data to the portable handheld device via the establishing short range wireless communication.

Abstract: A power supply approach and mechanism for electrical devices using a polarity-insensitive two-wire bus that can carry data and power. However, some devices, such as CO2 sensors and secure digital memory cards, may need certain amounts of energy for measuring and writing data, respectively, that are more intense than the amount of energy available on the two-wire bus. Sensor, card and other device data may be conveyed by the two-wire bus. The present approach and mechanism may convert power from the two-wire bus into intense energy that can enable the sensors, cards and other devices to satisfactorily operate. A current limiter may be incorporated to protect the two-wire bus from loss of data and energy for slave devices on the bus during a period of charging a storage cell in that an empty huge storage capacitor connected to bus directly could short the bus.
