Lockout display method for a packaged terminal air conditioner unit
A method for operating a packaged terminal air conditioner includes scrolling through a sequence of characters on a display of the user interface in response to an input at a user interface of the packaged terminal air conditioner. The user interface is locked when the sequence of characters scrolls on the display of the user interface. The display of the user interface includes a pair of segment displays. Each segment display of the pair of segment displays includes no less than seven segments. The sequence of characters includes the letters L, O, and C.
1. A method for operating packaged terminal air conditioner, comprising:
operating a compressor of a sealed system of the packaged terminal air conditioner in order to transfer heat between an interior coil and an exterior coil of the sealed system; and
in response to an input at a user interface of the packaged terminal air conditioner, scrolling through a sequence of characters on a display of the user interface,
wherein the user interface is locked when the sequence of characters scrolls on the display of the user interface,
wherein the display of the user interface comprises only two segment displays, and each segment display of the only two segment displays is a seven-segment display, and
wherein the sequence of characters consists of the letters L, O, and C.
2. The method of claim 1 , further comprising presenting a pair of numbers on the display of the user interface after scrolling through the sequence of characters.
3. The method of claim 2 , wherein the pair of numbers corresponds to a set temperature of the sealed system.
4. The method of claim 2 , further comprising repeating the sequence of characters on the display of the user interface after presenting the pair of numbers on the display of the user interface.
5. A packaged terminal air conditioner unit, comprising:
a sealed system positionable within a casing, the sealed system having a compressor, an interior coil and an exterior coil, the compressor operable to increase a pressure of a refrigerant;
a user interface having a display with only two segment displays, each segment display of the only two segment displays being a seven-segment display;
a controller in operative communication with the compressor and the user interface, the controller configured for
operating the compressor in order to transfer heat between the interior coil and the exterior coil; and
in response to an input at the user interface, scrolling through a sequence of characters on the display of the user interface at least twice,
wherein the user interface is locked when the sequence of characters scrolls on the display of the user interface, and
wherein the sequence of characters consists of the letters L, O, and C.
6. The packaged terminal air conditioner unit of claim 5 , wherein the controller is further configured for presenting a pair of numbers on the display of the user interface after scrolling through the sequence of characters.
7. The packaged terminal air conditioner unit of claim 6 , wherein the pair of numbers corresponds to a set temperature of the sealed system.
8. The packaged terminal air conditioner unit of claim 6 , wherein the controller is further configured for repeating the sequence of characters on the display of the user interface after presenting the pair of numbers on the display of the user interface.
