摘要:
An HVAC controller may include an upper housing having a front and a back, the back including a center. A lens dial including an engagement portion may be rotatably secured relative to the upper housing. A set point operator may include a first portion that is disposed about the upper housing center as well as a second portion that is adapted to interact with the lens dial engagement portion. A mechanical movement to electrical signal converter such as a potentiometer may be disposed within the HVAC controller such that the first portion of the set point operator communicates with the potentiometer.

A foldable truss member suitable for commercial displays includes a plurality of side members that are adjacently hinged together. The side members include support members and bridging members having extensions. The side members are joined into a foldable structure with a hinge member between the support member and extensions of adjacent side members. A display structure can be formed by connecting locking members between two truss members.
