Match the fan control module’s voltage rating to the fan’s supply voltage, since a mismatch can prevent proper operation or damage equipment. Check that the module supports the fan’s motor type; the modules in this category are described for standard paddle-type ceiling fans, so verify compatibility before using one with a different motor design.

Stepped-speed fan control modules switch a compatible fan among preset speed levels, such as the four speeds offered by some controls for standard paddle-type ceiling fans. Variable-speed modules adjust fan speed across a range rather than selecting fixed steps, and they need to match the fan’s control method.

Fan control modules can connect compatible ceiling fans to a smart home system and let you include fan operation in climate-control schedules. Compatibility and scheduling options depend on the module, fan, and system configuration.

Before adding a fan control module, check its rated voltage, supported fan type, and wiring diagram against the circuit and ceiling fan; some controls in this category are designed for 120 V standard paddle-type ceiling fans. Turn off the circuit and verify it is de-energized, then confirm the electrical box has room for the module and its wiring before installation.
