Abstract

Implementations of lighting control systems and methods are described and claimed herein. An exemplary remote control system comprises a wireless interface configured to receive instructions from a wireless station in a building automation network. A ballast table identifying ballast control points is stored in computer-readable memory. A processor operatively associated with the wireless interface and the ballast table uses the ballast table to generate electronic control signals identifying ballast control points corresponding to the instructions received at the wireless interface.

Claims

1. A building automation network with remote lighting control system comprising:

a CAN bus;

a keypad device connected to the CAN bus, the keypad issuing lighting commands over the CAN bus;

a wireless station connected to the CAN bus, the wireless station converting lighting commands issued over the CAN bus by the keypad into wireless instructions, and the wireless station issuing the wireless instructions; and

a remote lighting controller communicatively coupled to the wireless station, the remote lighting controller generating electronic control signals for at least one ballast corresponding to control points for the at least one ballast based of the wireless instructions.

2. The building automation network with remote lighting control system of claim 1, further comprising a wireless interface at the remote lighting controller, the wireless interface receiving the wireless instructions from the wireless station.

3. The building automation network with remote lighting control system of claim 1, further comprising a ballast table stored in computerreadable memory at the remote lighting controller, the ballast table identifying the control points.

4. The building automation network with remote lighting control system of claim 1, further comprising a processor at the remote lighting controller, the processor generating the electronic control signals.

5. The building automation network with remote lighting control system of claim 1, wherein said lighting controller provides substantially constant electronic control signals to the at least one ballast until another instruction is received.

6. The building automation network with remote lighting control system of claim 1, further comprising scripts stored in computerreadable memory at the lighting controller, the scripts executing to generate the electronic control signals.
