1. An HVAC controller, comprising:
- a controller housing having a front face with a central region;
a display in the central region of the front face of the controller housing; and
a movable interface member disposed around at least part of the central region of the front face of the controller housing and forming part of the front face of the controller housing, the movable interface member adapted to move relative to the central region of the front face of the controller housing;
wherein a value of a first parameter of the controller is initially displayed on the display, and motion of the movable interface member causes a value of a second parameter to be displayed on the display, replacing the display of the value of the first parameter.

Abstract
An HVAC controller with a simplified and/or lower cost user interface. In one illustrative embodiment, the HVAC controller includes two switches, a movable member, and a plurality of detents. The detents are configured to cause the two switches to be switched in a sequence when the movable member is moved. In some cases, a controller is coupled to the two switches, and may change an HVAC control parameter based on the switch sequence.

18. An HVAC controller comprising:
-
a controller housing having a front face with a central region; a liquid crystal display in the central region of the front face of the controller housing; and an annular shaped rotatable interface member disposed around at least part of the central region of the front face of the controller housing, and forming part of the front face of the controller housing, wherein the rotatable interface member rotates relative to the central region of the front face of the controller housing, wherein rotation of the rotatable interface member can be used to adjust one or more operating parameters of the HVAC controller, at least one of the adjusted parameters being displayed on the liquid crystal display.

19. An HVAC controller comprising:
-
a controller housing having a front face with a central region; a liquid crystal display disposed in the central region for displaying an operating parameter of the HVAC controller; and a rotatable interface member extending around the central region of the controller housing, the rotatable interface member being rotatable relative to the central region, wherein rotation of the rotatable interface member can be used to select one or more operating parameters of the HVAC controller for display on the liquid crystal display. - View Dependent Claims (20, 21)
