     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT  
       [0002]     Not applicable to this application.  
       BACKGROUND OF THE INVENTION  
       [0003]      1 . Field of the Invention  
         [0004]     The present invention relates generally to thermostats and more specifically it relates to a thermostat adjustment system for efficiently conserving energy within a thermostatically controlled zone.  
         [0005]      2 . Description of the Related Art  
         [0006]     Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.  
         [0007]     Thermostats have been in use for years. Typically, thermostats are utilized to regulate a temperature within a particular zone. The thermostat generally maintains a desired temperature by controlling the heat in and out of the zone. Thermostats are generally set manually by the user to the desired temperature; however in recent years thermostats have also included remote control devices to adjust the set temperature of the thermostat.  
         [0008]     Many people waste hundreds or even thousands of dollars every year by leaving their thermostat at the normal temperature when not needed (i.e. at work, sleeping, vacation, etc.). To overcome this waste of energy and money the user must generally set their thermostat or thermostats to an energy saving mode (i.e. temperature similar to an outside temperature) while they are away from their home or office. Because of the inconvenience associated with doing so and the potential for forgetting by consumers, consumers do not generally adjust the temperature on their thermostats for each zone of their home or office when away.  
         [0009]     Different thermostat devices have been utilized in the past to overcome this obstacle of routinely setting the thermostat to energy saving mode. One of these devices is a programmable thermostat. The programmable thermostat generally allows the consumer to preset their thermostat to a certain temperature at a given time or given day, wherein the given day or given time is generally meant to be part of a routine. A main disadvantage of the programmable thermostats are that consumers generally have changing schedules and are generally somewhat unpredictable in the times that they will be at home. For this reason programmable thermostats may be more of an inconvenience than a benefit.  
         [0010]     Remote controlled thermostats generally allow the consumer to adjust their thermostat up or down by one degree at a time. These remote controlled thermostats generally only control one thermostat, wherein many consumers have multiple different thermostats throughout their home or office. Because of the general lack of efficiency and practicality in the prior art there is the need for a new and improved thermostat adjustment system for efficiently conserving energy within a thermostatically controlled zone.

The first adjustment members  28  may also be preset at the time of manufacture of the transmitter unit  20  or the first adjustment members  28  may be set by the user at the time of installation of the transmitter unit  20  and the thermostat  30 . The first adjustment members  28  allow the user to set a unique access code for the transmitter unit  20  so as to not interfere with other household objects and to prevent the transmitter unit  20  from controlling undesired thermostats  30 . A similar access code is then set upon the second adjustment members  38  of thermostats  30  that the user desires to control.  
         [0000]     C. Thermostat  
         [0040]     The thermostat  30  is controlled by the transmitter unit  20  as illustrated in  FIG. 1  and  4 . It is appreciated that multiple thermostats  30  may be utilized with the present invention, wherein the transmitter unit  20  is able to toggle temperature settings of the multiple thermostats  30 . The thermostat  30  is also preferably comprised of a digital thermostat  30  as shown in  FIGS. 5 and 6 . The thermostat  30  further preferably includes normal thermostat  30  functions common in the art, such as but not limited to control of heating, control of ventilation, control of air conditioning and programmable features to set different temperature set points for different times of the day/week.  
         [0041]     The thermostat  30  includes at least one circuit board positioned within the thermostat  30 . The thermostat  30  includes a receiver  39  to receive the electromagnetic waves propagated by the transmitter unit  20 .

The receiver  39  is farther electrically connected to at least one circuit board. It is appreciated that the receiver  39  may also be configured to transmit signals, thus functioning as a transceiver, if it is desired to allow two way communications between the thermostat  30  and the transmitter unit  20 . Utilizing a transceiver could allow for additional functionality and security for the present invention.  
         [0042]     The thermostat  30  preferably includes a display area, wherein the display area preferably includes a normal setting display  32 , a toggle setting display  33  and a current temperature display  34  as shown in  FIGS. 5 and 6 . It is appreciated that the normal setting display  32 , the toggle setting display  33  and the current temperature display  34  may not all be displayed simultaneously, wherein the thermostat  30  may include a button to switch between displays  32 ,  33  and  34 .  
         [0043]     The normal setting display  32  preferably displays the normal temperature setting that the user has set upon the thermostat  30 . The toggle setting display  33  preferably displays the temperature setting that the user desires to utilize when they toggle the thermostat  30  with the transmitter unit  20 , such as but not limited to when they leave their home or office and wish to conserve energy by adjusting the thermostat  30  to a lower temperature setting. For example, during colder times of the year the user may desire to allow their house to cool when they are away from home rather than heating an empty home at a normal temperature setting. Likewise, during warmer times of the year the user may desire to allow their house to heat up when they are away from home rather than cooling an empty home at a normal temperature setting.  
         [0044]     The thermostat  30  includes at least one control button  36  as shown in  FIGS. 5 and 6 . The control button  36  is preferably able to access different settings of the thermostat  30 . For example the control button  36  may be depressed to access the toggle setting display  33 . The toggle setting display  33  may be adjusted with the first adjustment button  35  and the second adjustment button  37 . The normal setting display  32  may be adjusted in a similar manner to the toggle setting display  33 . It is appreciated that other methods of adjustment may be utilized with changing the temperature set points upon the normal setting display  32  and the toggle setting display  33 , such as but not limited to a slider adjustment member.  
         [0045]     The thermostat  30  also preferably includes a plurality of second adjustment members  38  as shown in  FIG. 5 . The second adjustment members  38  may be built into the thermostat  30  or positioned upon an outside of thermostat  30  as illustrated in  FIG. 5 . The second adjustment members  38  are further electrically connected to at least one circuit board. The second adjustment members  38  may also be comprised of a plurality of configurations, such as but not limited to a plurality of jumpers, toggle switches or a sensor.  
         [0046]     The second adjustment members  38  may also be preset at the time of manufacture of the thermostat  30  or the second adjustment members  38  may be set by the user at the time of installation of the thermostat  30  and the thermostat  30 . The second adjustment members  38  allow the user to set a unique access code for the thermostat  30  to receive a signal from the transmitter unit  20 .  
         [0047]     Alternatively, if it is desired to have independent control of the multiple thermostats  30 , the thermostats  30  could be set up with a common base code from the second adjustment members  38 , wherein a few bits of different code for each thermostat  30  would be present. The transmitter unit  20  could thus be programmed to transmit one code or the other, depending on which thermostat  30  is desired to be toggled. The transmitting of different codes could be accomplished through various methods, such as but not limited to utilizing multiple buttons upon the transmitter unit  20  or different button sequences.  
         [0048]     One example of an appropriate coding scheme would be to use the first 10 bits of a 12 bit address for the common base code. The first 10 bits would be programmed to the common base code upon all of the thermostats  30  in a given building  14  or location. The remaining 2 bits from the 12 bit address could be assigned to each of up to 4 thermostats  30 . It is appreciated that different coding schemes may be utilized with the present invention rather than the above example.  
         [0000]     D. Operation of Preferred Embodiment  
         [0049]     In use, the user first adjusts the normal setting display  32  upon the thermostat  30  to the desired comfort setting for when the user is present within the building  14  (i.e. home, office, etc.). The user also adjusts the toggle setting display  33  upon the thermostat  30  to the desired setting for when the user is away from the building  14  or sleeping within the building  14  (i.e. energy saving setting).  
         [0050]     When the user wishes to toggle between temperature settings (i.e. is leaving the building  14 , returning to the building  14 , etc.), the user depresses the toggle button  22 . The toggle button  22  then transmits a signal from the transmitter unit  20  to the thermostat  30  or thermostats  30  as illustrated in  FIG. 2 . The receiver  39  within the thermostat  30  then receives the signal and adjusts to the next temperature set point. If the thermostat  30  is currently set on the normal temperature set point the thermostat  30  adjusts to the toggle temperature set point. Likewise, if the thermostat  30  is currently set on the toggle temperature set point the thermostat  30  adjusts to the normal temperature set point as illustrated in  FIG. 3 . This process is simply repeated whenever the user desires to toggle the temperature set point upon the thermostat  30 .
