User interface for thermostat and related devices, systems, and methods

A user interface for adjusting a set point temperature of a thermostat configured to thermostatically control a radiator valve to selectively convey heating fluid to a radiator to adjust an environmental temperature toward the set point, the user interface comprising:

• a base;
• a user input member mounted on the base for movement with respect to the base through a range of motion including a home position, a set point decrease position, and a set point increase position, the user input member being operatively connected to the thermostat to decrease the set point temperature when the user input member is moved from the home position to the set point decrease position and to increase the set point temperature when the user input member is moved from the home position to the set point increase position;
• and
• a return mechanism operatively connected to the base and the user input member to automatically return the user input member to the home position after it is moved to either of the set point decrease position and the set point increase position and released, wherein the return mechanism comprises resiliently deformable hub member configured to resiliently deform when the user input member is moved from the home position toward either of the set point decrease position and the set point increase position and to rebound to return the user input member to the home position when the user input member is released.
