Adaptive capacitor section for fan speed control

A fan system comprising:

• a ceiling fan comprising a fan motor, the fan motor configurable to operate at a plurality of speed settings;
• and
• a fan controller configured to control power delivery to the ceiling fan, the fan controller including,
• a first capacitor,
• a second capacitor having a capacitance that is greater than a capacitance of the first capacitor,
• a power meter circuit, and
• one or more control devices configured to,
• obtain, via the power meter circuit, data indicative of electrical power a fan motor of the ceiling fan draws from the power source,
• determine a size of the fan motor based, at least in part, on the data,
• select the first capacitor or the second capacitor as a selected capacitor based at least in part on the determined size of the fan motor,
• obtain data indicative of a user-request to operate the fan motor at a lowest speed setting of a plurality of speed settings for the fan motor, and
• in response to the data indicative of the user-request, couple the fan motor to the power source via the selected capacitor.

A method of controlling a ceiling fan comprising:

• obtaining, by one or more control devices of a fan controller, data indicative of electrical power a fan motor of a ceiling fan draws from a power source;
• determining, by the one or more control devices, a size of the fan motor based, at least in part, on the obtained data;
• and
• selecting one of a first capacitor or a second capacitor as a selected capacitor based, at least in part, on the determined size of the fan motor, wherein the second capacitor has a capacitance that is greater than a capacitance of the first capacitor;
• and
• coupling the fan motor to the power source via the selected capacitor.
