Abstract

A controller unit for communicating with and controlling one or more discrete air conditioner units within a building is disclosed. In some instances, the discrete air conditioner controller may be configured to receive signals in a first signal format from a central coordinator and to transmit signals to the one or more discrete air conditioner units in a second signal format. The first signal format and second signal format may be different wireless formats. In some cases, the controller unit may store a programmable operating schedule, which may be updated via the central coordinator.

Claims

1. A controller unit for controlling a discrete air conditioning unit mounted to a wall, ceiling or window of a room of a building, the controller unit comprising:

a housing including one or more features to aid in mounting the controller unit to a surface of the building;

a memory located within the housing for storing a programmable operating schedule for a discrete air conditioning unit, wherein the programmable operating schedule includes two or more time periods, and each time period includes a corresponding programmable temperature set point;

a first wireless interface for communicating with a central coordinator of the building;

a second wireless interface for communicating with the discrete air conditioning unit, the first wireless interface using a different communication protocol than the second wireless interface;

a temperature sensor; and

a controller located within the housing and coupled to the memory, the first wireless interface, the second wireless interface, and the temperature sensor, the controller configured to send out one or more commands to the discrete air conditioning unit via the second wireless interface to activate and/or deactivate the discrete air conditioner unit in a manner that regulates the temperature in the room serviced by the discrete air conditioning unit in accordance with the programmable temperature set points of the programmable operating schedule stored in the memory, the controller also configured to receive one or more schedule updates to the programmable operating schedule from the central coordinator of the building via the first wireless interface.

2. The controller unit according to claim 1, further comprising an occupancy sensor.

3. The controller unit according to claim 1, wherein the second wireless interface is an infrared wireless interface.

4. The controller unit according to claim 3, wherein the first wireless interface is a mesh wireless network interface.

5. The controller unit according to claim 1, wherein the first wireless interface is an ad hoc wireless network interface.

6. The controller unit according to claim 1, wherein the first wireless interface is a wifi wireless network interface.

7. The controller unit according to claim 1, wherein the controller is further configured to transmit a signal indicative of a temperature sensed by the temperature sensor via the first wireless interface.

8. The controller unit according to claim 1, wherein the controller unit is battery powered.

9. The controller unit according to claim 1, wherein the controller is powered by a line voltage with battery backup.

10. A controller unit for controlling a discrete air conditioning unit mounted in a wall, ceiling or window of a building, the controller unit comprising:

a housing;

a first wireless interface for communicating with a central coordinator of the building;

a second wireless interface for communicating with the discrete air conditioning unit, the first wireless interface using a different communication protocol than the second wireless interface;

a memory for storing one or more operating parameters including a temperature set point;

a temperature sensor for sensing a temperature in or around the housing; and

a controller located within the housing and coupled to the first wireless interface, the second wireless interface, the memory and the temperature sensor, the controller configured to send out one or more commands to the discrete air conditioning unit via the second wireless interface to activate and/or deactivate the discrete air conditioner unit in a manner that regulates the temperature sensed by the temperature sensor in accordance with the temperature set point stored in the memory, the controller further configured to receive one or more set point updates from the central coordinator of the building via the first wireless interface, and to store the one or more set point updates in the memory.

11. The controller unit according to claim 10, wherein the first wireless interface is a radio frequency (RF) wireless interface for sending and/or receiving RF signals, and the second wireless interface is an infrared (IR) wireless interface for sending and/or receiving IR signals.
