HVAC controls or controllers including alphanumeric displays
View Patent ↗Disclosed are exemplary embodiments of controls for heating, ventilation, and/or air conditioning systems. In an exemplary embodiment, a control for a heating, ventilation, and/or air conditioning system includes an alphanumeric display and one or more input device. A processor of the control is configured to receive a user input through the input device(s), and in response to the user input, reorient a display of a message relative to the alphanumeric display.
1. A HVAC appliance control comprising:
a microcontroller having a processor and memory configured to control an HVAC appliance using operational parameters stored in the memory;
an alphanumeric display connected with the microcontroller; and
one or more input devices operable by a user to input one or more of the operational parameters in response to one or more of a plurality of menu options;
the microcontroller configured to:
display the plurality of menu options on the alphanumeric display, the menu options including an option to rotate a message on the display;
receive through the one or more input devices a user input indicating the option to rotate a message; and
in response to the user input, reorient a display of a message, from a first message orientation relative to the alphanumeric display, to a second message orientation relative to the alphanumeric display.
2. The control of claim 1 , wherein the alphanumeric display comprises a multiple-segment LED display.
3. The control of claim 1 , wherein the alphanumeric display comprises a LED dot matrix display.
4. The control of claim 1 , wherein the alphanumeric display comprises (a) three seven-segment light-emitting diode (LED) displays or (b) a 64-dot LED dot matrix display.
5. The control of claim 1 , wherein:
the one or more input devices comprise one or more push buttons; and
the microcontroller is configured to rotate the display of the message by an angle of rotation selected via at least one of the one or more push buttons.
6. The control of claim 1 , wherein the microcontroller is configured to reorient the display of the message by 180 degrees relative to the alphanumeric display.
7. The control of claim 1 , wherein the microcontroller is configured to rotate the message for display on the alphanumeric display by one or more angle increments.
8. The control of claim 1 , wherein the microcontroller is configured to control the HVAC appliance in response to commands from another HVAC controller.
9. The control of claim 1 , comprised by one or more of the following: a furnace control, an air conditioning control, a heat pump control, an air handler control, an integrated control, and a unitary control.
10. The control of claim 1 , wherein the one or more input devices comprises a two-position switch user-activatable to select a menu option displayed on the display and to select a change of display orientation.
11. A HVAC appliance control comprising:
a microcontroller having a processor and memory configured to control an HVAC appliance using operational parameters stored in the memory;
one or more light-emitting diode (LED) displays connected with the microcontroller and operable for displaying alphanumeric characters; and
a plurality of two-position switches configured to be operable by a user to input one or more of the operational parameters in response to one or more of a plurality of menu options;
the microcontroller configured to display the plurality of menu options on the alphanumeric display, the menu options including an option to rotate a message on the one or more LED displays;
the two-position switches operable to select the option to rotate the message on the one or more LED displays from a first message orientation relative to the one or more LED displays, to a second message orientation relative to the one or more LED displays.
12. The control of claim 11 , wherein:
the one or more light-emitting diode (LED) displays comprises at least two multiple-segment light-emitting diode (LED) displays and/or a dot matrix display; and/or
the plurality of two-position switches comprises at least two momentary push buttons.
13. The control of claim 11 , comprised by one or more of the following: a furnace control, an air conditioning control, a heat pump control, an air handler control, an integrated control, and a unitary control.
14. The control of claim 11 , wherein the one or more light-emitting diode (LED) displays comprises at least two multiple-segment LED displays, and wherein the orientation of the message for display on the multiple-segment LED displays is changeable in accordance with user input.
