Abstract:
An HVAC actuator configured to actuate an HVAC component may include a rotatable output shaft having a full range of rotation between a first end position and a second end position, a drive mechanism configured to selectively drive the output shaft, and a housing having a front side that faces away from the HVAC component. The HVAC actuator may include a range adjustment lever manipulatable from the front side of the housing that allows a user to selectively limit rotation of the output shaft to a reduced range that is a subset of the full range. In some instances, the range adjustment lever allows the user to select between two or more predetermined reduced ranges. The two or more predetermined reduced ranges may each include the first end position but have a different second stop position, or include the second end position but have a different first stop position.
