Abstract: A ceiling fan or ceiling fan includes a body defining an interior passage having an inlet and an outlet provided on the body. The inlet, outlet, and interior passage can be annular. An impeller is mounted within the interior passage and driven by a motor mounted within the body to draw a volume of air through the interior passage from the inlet to the outlet. A movable deflector including an inner angled surface and a lower angled surface is provided at the outlet to direct the airflow in a generally outward or generally downward direction, respectively.

Abstract: A ceiling fan includes a motor housing and a motor enclosed by the motor housing. A set of blades can extend from the motor housing and be operably coupled to the motor. The motor can include a rotor assembly and a stator assembly. The motor housing can include an upper housing and a lower housing.

Abstract: A remote controllable thermostat has an on-board power supply with batteries, a microcontroller having a timer, a temperature sensor, a temperature set point control controller and an RF receiver. The thermostat also has HVAC state control means for generating HVAC control signals in response to sensed temperatures being outside of control set point range and for periodically connecting and disconnecting the RF receiver from the power source to conserve battery power. Where the thermostat has user mode selector switches, the microcontroller is further programmed to read their state only periodically for additional battery power conversation.
