Abstract:
1. An HVAC controller comprising: an upper housing, the upper housing having a front and a back, the back including a center; a lens dial secured adjacent to the front of the upper housing, the lens dial being rotatable relative to the upper housing about a rotation axis, the lens dial having an engagement portion that is spaced laterally from the rotation axis of the lens dial, and extends through an opening in the upper housing toward the back of the upper housing, wherein when the lens dial is secured adjacent to the upper housing, at least part of the upper housing is situated between the rotation axis of the lens dial and the engagement portion; a set point operator including a first portion that is rotatable about the rotation axis of the lens dial and a second portion that extends over toward and engages the engagement portion of the lens dial such that rotation of the lens dial results in movement of the engagement portion along an arc, causing the second portion of the set point operator to move along an arc and to rotate the first portion of the set point operator about the axis of rotation of the lens dial; and a mechanical movement to electrical signal converter disposed within the HVAC controller such that the first portion of the set point operator communicates with the mechanical movement to electrical signal converter.
