First Claim
1. A building control system for controlling one or more building components that service a building, the building control system comprising:
- a central coordinator comprising an wireless interface for wirelessly sending and receiving one or more wireless signals, a user interface for accepting one or more user interactions from a user, and a controller coupled to the input/output port, the user interface and the memory, the central coordinator is powered by a line voltage;
a discrete air conditioner controller configured to communicate with and control one or more discrete air conditioner units that service a building, the discrete air conditioner controller including a first wireless interface for wirelessly communicating with the central coordinator via a mesh network, and a second wireless interface for communicating with one or more discrete air conditioner units, the second wireless interface includes an infrared (IR) interface for transmitting IR control codes to the one or more discrete air conditioner units, the discrete air conditioner controller is powered by a battery;
the discrete air conditioner controller further includes one or more sensors, wherein the one or more sensors include one or more of a temperature sensor, an occupancy sensor, a humidity sensor and a light sensor; and
wherein the discrete air conditioner controller is configured to transition between a sleep mode in which less power is consumed and an active mode in which more power is consumed, wherein in the active mode the discrete air conditioner controller is configured to transmit over the mesh network, and wherein in the sleep mode the discrete air conditioner controller is configured to not transmit over the mesh network.

Abstract
A building control system includes a central coordinator and one or more discrete air conditioner controllers configured to communicate with one or more discrete air conditioner units servicing the building. In some instances, a discrete air conditioner controller may be configured to transition between a sleep mode and an active mode. The discrete air conditioner controller may also be configured to transmit over a mesh network in the active mode and to not transmit over the mesh network in the sleep mode. The discrete air conditioner controller may be configured to transition between the sleep mode and the active mode according to a schedule dictated by the central coordinator. Alternatively, or in addition, the discrete air conditioner controller may be configured to transition between the sleep and active modes in accordance with a beacon signal received from the central coordinator.

21. A method of controlling a discrete air conditioner unit that services a building, the method comprising:
-
transmitting a command over a first wireless communications path from a central coordinator of the building to a discrete air conditioner controller located near a discrete air conditioner unit mounted on a ceiling, a wall or a window of the building; in response to receiving the command over the first wireless communications path, transmitting a command over a second wireless communications path from the discrete air conditioner controller to the discrete air conditioner unit for controlling operation of the discrete air conditioner controller, wherein the first wireless communications path is not compatible with the second wireless communications path; sensing one or more sensed parameters at the discrete air conditioner controller, and if the one or more sensed parameters meet one or more predetermined criteria, transmitting one or more commands over the second wireless communications path from the discrete air conditioner controller to the discrete air conditioner unit for controlling operation of the discrete air conditioner controller; transitioning the discrete air conditioner controller between a sleep mode in which less power is consumed and an active mode in which more power is consumed, wherein in the active mode the discrete air conditioner controller is configured to transmit data to the central coordinator of the building via the first wireless communications path, and wherein in the sleep mode the discrete air conditioner controller is configured to not transmit data over the first wireless communications path.
