Motor Control Device

A lighting and fan control method, comprising:

• providing, by a control circuit, a first control signal at a first load control circuit output, the first control signal to cause a first load control circuit to control power delivered from an AC power source to a first circuit that includes a lighting load;
• providing, by the control circuit, a second control signal at a second load control circuit output, the second control signal to cause to a second load control circuit to control power delivered from the AC power source to second circuit that includes a fan motor load;
• detecting, by the control circuit, an open circuit condition in the first circuit;
• responsive to detection of the open circuit condition in the first circuit:
• generating, by the control circuit, a switch output signal at a switching circuit output, the switch output signal to cause a power supply circuit coupled to the AC power source to transition from an electrically parallel connection with the first load control circuit to an electrically parallel connection with the second load control circuit.

A non-transitory, machine-readable, storage device that includes instructions that, when executed by lighting and fan control circuit, cause the lighting and fan control circuit to:

• provide a first control signal at a first load control circuit output, the first control signal to cause a first load control circuit to control power delivered from an AC power source to a first circuit that includes a lighting load;
• provide a second control signal at a second load control circuit output, the second control signal to cause to a second load control circuit to control power delivered from the AC power source to second circuit that includes a fan motor load;
• determine whether an open circuit condition is present in the first circuit;
• responsive to the determination that the open circuit condition exists in the first circuit:
• generate a switch output signal at a switching circuit output, the switch output signal to cause a power supply circuit coupled to the AC power source to transition from an electrically parallel connection with the first load control circuit to an electrically parallel connection with the second load control circuit.
