Description
TECHNICAL FIELD
[0001] The disclosure relates generally to controllers and more
particularly to special purpose controllers.
BACKGROUND
[0002] Special purpose controllers are commonly used today to
control and manage a wide variety of equipment and systems. Unlike
general-purpose computer systems, such as personal computers,
special purpose controllers are designed and used for specific
applications. Special purpose controllers can include, for example,
traffic light controllers, factory equipment controllers, building
controllers such as HVAC controllers, security system controllers,
lighting controllers, and other types of application specific
controllers or systems. Some special purpose controllers are
completely encapsulated by or dedicated to the devices or systems
that they control.
[0003] Special purpose controllers can be difficult to set up,
program and operate, as they frequently have relatively small
displays and/or a menu structures that are not very intuitive. As a
result, many users get frustrated when interacting with such
special purpose controllers, and ultimately, often fail to take
advantage of many of their features and/or capabilities. Thus, a
need remains for a special purpose controller that is more
intuitive and easy to set up, program and/or operate.
SUMMARY
[0004] The present disclosure relates to a special purpose
controller that includes a user interface that is easy to set up,
program and/or operate. In one illustrative embodiment, a special
purpose controller, such as a temperature controller, is provided
that includes a controller and a user interface. The controller has
a control algorithm for controlling one or more pieces of equipment
that are located remotely from the controller, such as one or more
pieces of HVAC equipment. The user interface is configured to
display a hierarchical menu structure on the display, and permits a
user to traverse the hierarchical menu structure. In some cases,
the user interface may be configured to display a number of
programming menus that display and/or solicit changes to one or
more programmable parameters.
[0005] In some instances, the special purpose controller may be
configured to display one or more breadcrumbs that provide an
indication to the user of a current location within the
hierarchical menu structure. This may help prevent the user from
becoming lost or confused as to where he/she is within the
hierarchical menu structure.
[0006] Alternatively, or in addition, the special purpose
controller may be configured to display instructional information
that relates to a particular programming parameter to be entered or
selected. The instructional information may provide instructions on
how to respond to a corresponding menu option. In some instances,
all menus that solicit a value or a selection from a user display
instructional information in a common or fixed area of the display.
Also, and in some cases, the instructional information may be
presented in a consistent or common format. By providing the
instructional information in a common or fixed area of the display
and/or in a consistent format, a more intuitive look and feel may
be achieved, making the user interface easier to understand and
follow.
[0007] In some cases, the user interface may include a number of
buttons that can be used in conjunction with the menus. The
particular arrangement of the buttons, along with interaction of
the buttons with the menus, also can make the user interface more
intuitive to use.
[0008] The above summary is not intended to describe each disclosed
embodiment or every implementation of the present invention. The
Figures and Detailed Description that follow more particularly
exemplify these embodiments.

DETAILED DESCRIPTION
[0015] The following description should be read with reference to
the drawings, in which like elements in different drawings are
numbered in like fashion. The drawings, which are not necessarily
to scale, depict selected embodiments and are not intended to limit
the scope of the invention. Although examples of construction,
dimensions, and materials are illustrated for the various elements,
those skilled in the art will recognize that many of the examples
provided have suitable alternatives that may be utilized.
[0016] The present invention relates to special purpose
controllers. For illustrative purposes, some features are discussed
herein with respect to an environmental control system. However,
this is not to be limiting. It should be understood that the
present invention is equally applicable to a wide variety of
special purpose controllers that are adapted to control a wide
variety of devices or equipment.
[0017] An environmental control system may be used to control one
or more environmental conditions of a space, such as temperature,
humidity, ventilation, lighting, and the like. A space may include,
for example, a building or a portion of a building, an office, a
barn or similar structure, water in a swimming pool, and the like.
Such an environmental control system may include one or more
environmental control devices. The environmental control devices
may include a control algorithm that is adapted to control, for
example, a swimming pool heater, a ventilator, a furnace, an air
conditioner, a boiler system, a security system, lighting or any
other type of device or equipment. In many cases, the equipment
that is controlled by the environmental control device may be
located remotely from the environmental control device, but this is
not required in all embodiments. In some instances, the
environmental control device may be an HVAC controller, such as a
temperature controller (e.g. a thermostat).
[0018] FIG. 1 is a block diagram of an environmental control system
12 including an illustrative but non-limiting environmental control
device 10. Environmental control device 10 may be in communication
with environmental control equipment 14 and/or sensors 16.
Environmental control equipment 14 may include any equipment that
is or can be configured to condition or otherwise alter or detect
the environmental conditions within a space. Environmental control
equipment 14 may include, for example, HVAC equipment such as
heating, cooling and/or ventilating equipment, or perhaps security
and/or lighting equipment.
[0019] Sensors 16 may be any sensor or sensors that can sense or
otherwise detect environmental conditions within a space and
communicate this information to environmental control device 10.
Examples of suitable sensors 16 include temperature sensors,
humidity sensors, motion sensors, light detectors, etc. In some
cases, sensors 16 may include safety-related sensors such as, for
example, carbon monoxide sensors. As illustrated, sensors 16 are in
communication with environmental control device 10. In some cases,
sensors 16 may instead, or in addition, be in communication
directly with environmental control equipment 14, if desired.
[0020] In some instances, environmental control device 10 may
include or be composed of several elements that may be combined
within a single housing or structure or may, if desired, be
disposed within two or more distinct housings. In the illustrative
embodiment, environmental control device 10 includes a controller
18 and a user interface 20. An I/O segment 22 may provide
electrical connections or otherwise permit communication between
environmental control device 10 and external elements such as
environmental control equipment 14 and/or sensors 16. In some
cases, environmental control device 10 may also include a relay
segment 24 that can, through I/O segment 22, selectively provide
power to externally located devices such as environmental control
equipment 14.
[0021] Controller 18 may be configured to display appropriate
prompts on user interface 20, and to accept user inputs from user
interface 20. While not expressly illustrated, controller 18 may
include memory for storing menus, parameters and other operational
data, as well as for storing programming instructions. Controller
18 may include flash memory or other types of memory, as known.
[0022] Along with operating user interface 20, controller 18 may
have a control algorithm for controlling one or more pieces of
equipment, such as environmental control equipment 14. The control
algorithm may provide appropriate commands for operating
environmental control equipment 14 as well as accepting sensor
input from sensors 16. In some cases, controller 18 may provide
command signals directly to I/O segment 22 that are then
transmitted to environmental control equipment 14. In other cases,
controller 18 may transmit command signals to relay segment 24
that, in turn, selectively provide power or other control signals
to one or more devices within environmental control equipment
14.
[0023] User interface 20 may take a wide variety of different
forms. User interface 20 can include, for example, one or more of
an alpha-numeric display, a graphical display, and/or a key pad
having one or more keys or buttons. In some cases, user interface
20 can include a touch screen that can be used to both display
appropriate information to the user, as well as to accept
information from the user, as desired. In some instances, user
interface 20 may include a display screen and one or more tactile
buttons separate from the display screen, A display screen may be
an LED display, an LCD display, or any other suitable display
format discernible to the human eye. Buttons, if included, may be
used to scroll through menus that are displayed on the display
screen, increase parameter values, decrease parameter values,
select values, and the like, as will be discussed in more detail
with respect to subsequent Figures.
[0024] FIG. 2 is a perspective view of an illustrative but
non-limiting environmental control device 10. The illustrative
environmental control device 10 includes a housing 26. In some
cases, and as illustrated, housing 26 may include a front housing
portion 28 and a rear housing portion 30. Front housing portion 28
may have a height that is at least about twice its width, or may
have a height that is about three times its width, but this is not
required. In some instances, one or more hinges 32 disposed along
one side of housing 26 may hingedly secure front housing portion 28
to rear housing portion 30. If desired, one or more apertures 34
may be disposed along a side of housing 26 and may accommodate
fasteners such as screws or bolts (not shown) to help fasten front
housing portion 28 to rear housing portion 30. In other instances,
front housing portion 28 may, for example, simply snap or otherwise
engage rear housing portion 30.
[0025] The illustrative environmental control device 10 includes a
display 36 and a control pad 38. In some instances, display 36 and
control pad 38 may be considered, in tandem, a user interface 20
(FIG. 1). In some cases, control pad 38 may be disposed vertically
below display 36, but this is not required. The display 36 may
consume 10%, 20%, 30%, 40% or more of the front surface area of the
housing, and may have a vertical height that is at least 1.5 times
as great as its width. In this, relative vertical position merely
refers to the illustrated orientation, as environmental control
device 10 may function in any particular orientation. Display 36
may be used to display, for example, a variety of alphanumeric
characters, icons, or any other type of information, as desired. In
some cases, display 36 may be considered as including an upper
portion 40 and a lower portion 42.
[0026] In some operating conditions, alphanumeric characters such
as letters and numbers may be displayed on display 36, and the
information may be displayed on all or substantially all of display
36. In some operating or programming conditions, upper portion 40
and/or lower portion 42 may be reserved or dedicated to displaying
particular information pertaining to the operating or programming
condition that environmental control device 10 is currently in.
[0027] For example, in some circumstances, upper portion 40 of
display 36 may be used to display breadcrumb information.
Controller 18 (see FIG. 1) may be programmed to display a
hierarchical menu structure on display 36, and may also display one
or more breadcrumbs on the upper portion 40 of display 36. The
breadcrumbs may provide an indication to the user of a current
location within the hierarchical menu structure, as will be
illustrated further in subsequent Figures. In some instances, the
breadcrumb information may provide a hierarchical path of a current
location within the hierarchical menu structure, which may, if
desired, include a designator or label for each hierarchical level
down to the current level within the hierarchical menu
structure.
[0028] Each designator or label may be displayed vertically one
above the other within upper portion 40 of display 36, but this is
not required in all embodiments. For example, if three successive
levels of a hierarchical menu structure are available, a first
level breadcrumb may be displayed within upper portion 40 of
display 36. Once a second level has been selected, a second level
breadcrumb may be displayed within upper portion 40 of display 36,
vertically below the first level breadcrumb. Once a third level has
been selected, a third level breadcrumb may be displayed within
upper portion 40 of display 36, vertically below the second level
breadcrumb. Thus, and in this illustrative example, a user may see
how they reached a particular portion or level within a
hierarchical menu structure, and may have ready access to the
current menu location within the hierarchical menu structure. In
some cases, upper portion 40 of display 36 may accommodate a total
of one, two, three, four, five or more breadcrumbs.
[0029] In some instances, lower portion 42 may be used to display
instructional information pertaining to operating environmental
control device 10. For example, a user may be at a point within the
menu structure in which a particular parameter is to be set or
selected. In this situation, controller 18 (FIG. 1) may display
instructional information within lower portion 42 that tells a user
what parameter is being set or selected and/or how to set and/or
select the parameter. By always providing the instructional
information in the same region of the display, the user may quickly
understand where to look for help or guidance when operating the
operating environmental control device 10. However, it should be
recognized that in some embodiments the instructional information
need not always be displayed in the same region of the display.
[0030] In some instances, controller 18 may include a control
algorithm that uses a number of programmable control parameters.
The controller 18 may be adapted to display two or more programming
menus that each solicit from a user changes to one or more of the
programmable control parameters. Each programming menu may include
one or more user instructions that may be displayed within the
lower portion 42 of display 36. That is, and in some cases, the
lower portion 42 of the display may be dedicated to displaying
instructional information that relates to the particular
programming parameter to be entered or selected for that menu.
[0031] In some cases, the instructional information may provide
instructions on how to respond to a corresponding menu option. In
some instances, all menus that solicit a value or a selection from
a user display instructional information in a common or fixed area
of the display, such as lower portion 42. In some cases, the
instructional information may be presented in a consistent or
common format, such as "SELECT [A] FOR [B]" or "ENTER [A] FOR [B]",
where [A] describes the parameter and [B] describes what part of
the environment control device the selection applies. By providing
the instructional information in a common or fixed area of the
display, such as lower portion 42, and/or in a consistent format, a
more consistent look and feel may be achieved, making the user
interface more intuitive to use.
[0032] In some instances, at least one of the programming menus may
solicit a selection between two or more displayed choices, and the
instructional information displayed within lower portion 42 of
display 36 may ask the user to make a selection. On other
instances, at least one of the programming menus may solicit a
parameter value, and the instructional information displayed within
lower portion 42 of display 36 may instruct the user to enter a
parameter value.
[0033] In some instances, upper portion 40 of display 36 may be
reserved for displaying breadcrumb information while lower portion
42 of display 36 may be reserved for displaying instructional
information, at least for some menus of the hierarchical menu
structure. It will be recognized, however, that in some cases lower
portion 42 of display 36 may be used for breadcrumb information
while upper portion 40 of display 36 may be used for instruction
information. In some instances, display 36 may include an
intermediate portion 44 that may, in some cases, be used to display
breadcrumb information and/or instruction information, if desired.
In some cases, it is contemplated that intermediate portion 44 of
display 36 may provide additional display space for either the
breadcrumb information displayed in upper portion 40 of display 36
or the instructional information displayed in lower portion 42 of
display 36, if so desired.
[0034] Control pad 38 may include one or more buttons such as
electromechanical buttons. In some cases, control pad 38 may
include an up button 46 and a down button 48. A next button 50 and
a back button 52 may also be included in control pad 38. In some
cases, a program menu button 54 that may be configured to initiate
a programming mode may be disposed within control pad 38. Control
pad 38 may include a home button 56 that may be configured to
display a home page(s) on display 36. In some cases, the home
page(s) may display a value of one or more control parameters, a
value of a set point, a sensor input value and/or a control output
value, as well as other information as desired. In some instances,
up button 46, down button 48, next button 50, back button 52,
program menu button 54 and home button 56 may be the only buttons
present on the front of environmental control device 10, but this
is not required in all embodiments.
[0035] In some cases, up button 46 is positioned above down button
48, and next button 50 is positioned to the right of back button
52. In some instances, next button 50 is positioned to the right of
up button 46 and down button 48, and back button 52 is positioned
to the left of up button 46 and down button 48. In some
embodiments, up button 46, down button 48, next button 50 and back
button 52 may be collectively laterally centered within control pad
38 and/or with respect to the housing of the environmental control
device 10. Home button 56 may be positioned within an upper left
portion of control pad 38 while program menu button 54 may be
positioned within an upper right portion of control pad 38 as
shown.
[0036] As noted above, environmental control device 10 may provide
a hierarchical menu structure that includes a number of
hierarchical menus. In some cases, one or more of the menus may, in
a programming mode, query a user to enter a value or make a
selection. One or more of up button 46, down button 48, next button
50 and/or back button 52 may be used to enter the requested value
or make the requested selection.
[0037] In some instances, at least one of the menus includes, in
the programming mode, a first indicator for identifying a current
active menu on display 36 and one or more second indicators for
identifying currently available or selected sub-menus. The current
active menu may include a first indicator associated with the first
menu label for indicating that a menu immediately above the current
active menu may be activated by depressing back button 52. A second
indicator may be associated with a currently selected sub-menu for
indicating that the currently selected sub-menu may be activated by
depressing the next button 50, as will be further described
below.
[0038] FIG. 3 is back view showing the electrical connections of
the illustrative environmental control device 10. It is
contemplated that the illustrative environmental control device 10
may be adapted to provide a degree of flexibility in its
application. For example, environmental control device 10 may be
configured such that it can be powered either using line voltage
(120/240 volts), or a low voltage (24 volts) commonly associated
with HVAC and other control systems without requiring distinctly
different control devices. As shown in FIG. 3, environmental
control device 10 may include both a 24 volt power connection 60 as
well as a 120/240 volt power connection 62. Depending on the
specific environmental control equipment 14 (FIG. 1) that
environmental control device 10 is to control, an installer may
make the appropriate power connections to environmental control
device 10. In some cases, both power sources may be used.
[0039] The illustrative environmental control device 10 is also
