Abstract

A packaged terminal air conditioner unit is provided. The packaged terminal air conditioner unit can include a heater bank jumper configured to couple one or more heater banks to a controller associated with the packaged terminal air conditioner unit. The heater bank jumper can be selectively configurable to provide at least one shunt line to couple at least one contact point associated with the controller to at least one contact point associated with the one or more heater banks. In this manner, the heater bank jumper can be configured based at least in part on an amount of current provided to the packaged terminal air conditioner unit by an electric service.

First claim

What is claimed is:

1. A packaged terminal air conditioner unit, comprising:
a casing;
a compressor positioned within the casing, the compressor operable to increase a pressure of a refrigerant;
an interior coil positioned within the casing;
an exterior coil positioned within the casing opposite the interior coil;
one or more associated power relay coils;
a controller; and
a heater bank jumper coupled between the controller and one or more power relay coils, the heater bank jumper having one or more shunt lines configured to conduct one or more command signals from the controller to at least one of the one or more power relay coils, the one or more shunt lines being selectively configurable based at least in part on a current rating of a wall receptacle associated with the packaged terminal air conditioner unit.

2. The packaged terminal air conditioner unit of claim 1 , wherein the one or more power relay coils are configured to control the operation of one or more heater banks associated with the packaged terminal air conditioner unit.

3. The packaged terminal air conditioner unit of claim 2 , wherein only a subset of the heater banks is energized during a heating mode of the packaged terminal air conditioner unit.

4. The packaged terminal air conditioner unit of claim 3 , wherein the subset of heater banks is determined based at least in part on the current rating of the wall receptacle.

5. The packaged terminal air conditioner unit of claim 4 , wherein the shunt lines of the jumper are configured to conduct command signals only to the power relay coils that correspond to the subset of heater banks.

6. The packaged terminal air conditioner unit of claim 2 , wherein each heater bank is energized during a heating mode of the packaged terminal air conditioning unit.

7. The packaged terminal air conditioner unit of claim 1 , wherein the heater bank jumper is further coupled to a power cord.

8. The packaged terminal air conditioner unit of claim 7 , wherein the power cord is further coupled to a plug configured to fit in the wall receptacle.

9. The packaged terminal air conditioner unit of claim 8 , wherein the wall receptacle is associated with a power source.

10. The packaged terminal air conditioner unit of claim 8 , wherein the wall receptacle has a current rating of 15 amps, 20 amps, or 30 amps.

11. The packaged terminal air conditioner unit of claim 8 , where the power cord is further connected to a power connector configured to connect to one or more electrical components of the packaged terminal air conditioner unit.

12. The packaged terminal air conditioner unit of claim 1 , wherein the heater bank jumper is configured to fit in a receptacle located on the packaged terminal air conditioner unit, the receptacle having one or more contact points of the controller and one or more contact points of the power relay coils.

13. The packaged terminal air conditioner unit of claim 1 , wherein the one or more power relay coils are coupled to the heater bank jumper via one or more relay drivers.

14. A packaged terminal air conditioner unit comprising:
a casing extending between an exterior side portion and an interior side portion;
a compressor positioned within the casing, the compressor operable to compress a refrigerant;
a controller configured to control the operation of one or more associated power relay coils;
one or more heater banks coupled to the one or more power relay coils; and
a heater bank jumper coupled between the controller and the one or more associated power relay coils, the heater bank jumper having one or more conductive shunt lines configured to provide a path for current to flow from the controller to at least a subset of the power relay coils, wherein the conductive shunt line configuration is selectively configurable based at least in part on a current rating of a receptacle associated with the packaged terminal air conditioner unit.

15. The packaged terminal air conditioning unit of claim 11 , wherein the heater bank jumper is disposed between one or more contact point pairs, and wherein the one or more contact point pairs comprise a contact point of the controller and a contact point of a relay driver.

16. The packaged terminal air conditioning unit of claim 15 , wherein the relay driver powers operation of the one or more power relay coils.

17. The packaged terminal air conditioner unit of claim 14 , wherein each of the one or more power relay coils is configured to control the operation of at least one of the one or more heater banks.

18. The packaged terminal air conditioner unit of claim 14 , wherein the heater bank jumper is coupled to a power cord having a plug configured to fit in the receptacle.

19. The packaged terminal air conditioner unit of claim 18 , wherein the current rating of the receptacle is 15 amps, 20 amps, or 30 amps.
