Abstract

An example wall-mountable HVAC controller may include a controller module and a wall plate, with a hinge that allows the controller module to rotate relative to the wall plate. The hinge may provide an end stop that limits the rotation of the controller module relative to the wall plate, and/or may allow the controller module to be freely pulled away and disengaged from the wall plate if desired.

a wall plate including one or more first hinge structures, the wall plate configured to be secured to a wall;

a controller module configured to be releasably securable to the wall plate, the controller module including one or more second hinge structures configured to engage the one or more first hinge structures to form a hinge between the controller module and the wall plate, wherein the hinge enables the controller module to rotate away from the wall plate along a predetermined path and away from the wall to an end stop defined by the one or more hinge structures; and

a latch configured to be releasable by a user in order to release a top of the controller module from the wall plate without having to first pull the controller module away from the wall plate;

wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are configured to allow rotation of the controller module away from the wall plate while the one or more first hinge structures remain engaged with the one or more second hinge structures;

wherein the controller module is securable to the wall plate by both the latch and the hinge, wherein when the controller module is secured to the wall plate by the latch and the hinge, releasing the latch by the user allows the controller module to be rotated away from the wall plate via the hinge; and

wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are configured such that, after the latch releases the controller module from the wall plate, the controller module can be freely pulled away by the user and disengaged from the wall plate.

2. The wall-mountable HVAC controller of claim 1, wherein the controller module is configured to rotate away from the wall plate about a rotation axis, wherein the rotation axis does not intersect the wall plate nor the controller module.

3. The wall-mountable HVAC controller of claim 1, wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module include cooperating features that allow the controller module to rotate away from the wall plate but then interfere to define the end stop for the hinge, the end stop substantially preventing the controller module from rotating relative to the wall plate beyond a defined rotational limit.

4. The wall-mountable HVAC controller of claim 3, wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are positioned adjacent a bottom side of the wall-mounted HVAC controller and the latch is positioned adjacent a top side of the wall-mounted HVAC controller, and wherein the hinge is configured to suspend the controller module at the defined rotation limit when the controller module is rotated to the defined rotation limit.

5. The wall-mountable HVAC controller of claim 1, wherein at least some of the one or more first hinge structures and the one or more second hinge structures are structured with sufficient flexibility and/or lubricity that if a force is exerted on the controller module so as to rotate the controller module away from the wall plate past the end stop, the hinge releases without breakage of any of the one or more first hinge structures and the one or more second hinge structures.

6. The wall-mountable HVAC controller of claim 1, wherein the one or more first hinge structures and the one or more second hinge structures include:

a loop defining an opening, the opening defined by inner side walls of the loop, the loop including a first curved surface;

a tang; and

a second curved surface spaced from the tang,

wherein the tang is configured to extend into the opening of the loop, with the first curved surface of the loop cooperating with the second curved surface,

wherein one of the inner side walls of the loop is configured to engage the tang to at least partially define the end stop for the hinge.

7. The wall-mountable HVAC controller of claim 6, wherein after the latch releases the controller module from the wall plate, the controller module can be freely pulled away by the user and disengaged from the wall plate by removing the tang from the opening of the loop.

8. A wall-mountable HVAC controller comprising:

a wall plate having an upper half and a lower half, the wall plate including one or more first hinge structures in the lower half of the wall plate, the wall plate configured to be secured to a wall; and

a controller module configured to be releasably securable to the wall plate and including an upper half and a lower half, the controller module including one or more second hinge structures in the lower half of the controller module configured to engage the one or more first hinge structures to form a hinge between the controller module and the wall plate, wherein the hinge allows the controller module to rotate away from the wall plate and away from the wall; and

a connector for electrical and/or optical signals, the connector including a first connector portion attached to the upper half of the wall plate and a second connector portion attached to the upper half of the controller module, the first connector portion and second connector portion configured to automatically mate and de-mate as the controller module is rotated toward and away from the wall plate, respectively,

wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are configured such that, while rotating away from the wall plate, the controller module can be freely pulled away by the user and disengaged from the wall plate; and

wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are configured such that the hinge provides an end stop that limits the rotation of the controller module away from the wall plate such that when the wall plate is mounted to the wall, the controller module is rotatable under gravity until engaging the end stop.

9. The wall-mountable HVAC controller of claim 8, wherein the controller module is configured to rotate away from the wall plate about a rotation axis, wherein the rotation axis does not intersect the wall plate nor the controller module.

10. The wall-mountable HVAC controller of claim 8, wherein the controller module is securable to the wall plate by both a latch and the hinge, wherein when the controller module is secured to the wall plate by the latch and the hinge, releasing the latch allows the controller module to be rotated away from the wall plate via the hinge and away from the wall.

11. The wall-mountable HVAC controller of claim 8, wherein the end stop limits the rotation of the controller module away from the wall plate to less than 90 degrees.

12. The wall-mountable HVAC controller of claim 8, wherein the end stop limits the rotation of the controller module away from the wall plate to less than 40 degrees.

13. The wall-mounted HVAC controller of claim 8, wherein the one or more first hinge structures of the wall plate and the one or more second hinge structures of the controller module are configured such that forcing the controller module to rotate away from the wall plate beyond the end stop temporarily deforms but does not damage the hinge for future use.

14. The wall-mountable HVAC controller of claim 8, wherein the wall plate includes one or more terminals, the one or more terminals configured to receive a signal-carrying cable from external the HVAC controller, the one or more terminals communicatively coupled to the first connector portion of the connector.

19. The wall-mountable HVAC controller of claim 8, wherein the first connector portion and second connector portion are configured to automatically mate and de-mate as the controller module is rotated through less than 4 degrees of rotation.

15. A method of engaging and disengaging a control module from a wall plate of an HVAC controller, the wall plate and the controller module having cooperating hinge structures that form a hinge with an open stopped position that allows the controller module to be suspended from the wall plate at the open stopped position after a release mechanism is actuated, the hinge further allowing the suspended controller module to be lifted freely from the wall plate, the method comprising:

with the controller module secured to the wall plate, actuating the release mechanism;

after actuating the release mechanism, allowing the controller module to rotate about the hinge to the open stopped position, wherein while the controller module is rotated to the open stopped position, one or more control signal connections between the controller module and the wall plate become disrupted;

lifting the controller module away from the wall plate from the open stopped position;

mating the cooperating hinge structures of the wall plate and the controller module; and

rotating the controller module about the hinge until the controller module is secure against the wall plate via the release mechanism, wherein while the controller module is rotated and then secured against the wall plate via the release mechanism, reestablishing the one or more control signal connections between the controller module and the wall plate.

16. The method of claim 15 further comprising:

after lifting the controller module away from the wall plate from the open stopped position, removing one or more batteries from the controller module and placing one or more new batteries into the controller module.

17. The method of claim 15 further comprising:

after lifting the controller module away from the wall plate from the open stopped position, programming the controller module via a user interface of the controller module.

18. The method of claim 15, wherein actuating the release mechanism includes actuating the release mechanism with a single human finger.
