Q. Why is TXU Energy offering this program?
A. TXU Energy wants to help more Texans use less energy and do something good for the environment. Your participation in the TXU Energy Conservation Program and using the TXU Energy iThermostat™ can help the environment by allowing TXU Energy to briefly cycle your air conditioner on and off during peak demand periods. Reducing peak demand helps in three ways: 1) it can reduce the need to call on less-efficient generation, which costs more to operate; 2) it can reduce the need to build new generation facilities; and 3) it can reduce the strain on transmission facilities. All three benefits help keep electric rates in Texas as low as possible, while impacting the environment in a positive way. (This program is provided by TXU Energy, a retail electric provider. TXU Energy does not provide transmission, distribution or generation services.)

Q. What if I choose to change my plan, opt out of the pilot program or move?
A. The TXU Energy iThermostat is available to qualifying TXU Energy customers on any pricing plan. As always, you have the flexibility to change from one TXU Energy service plan to another (within the plan-specific terms of service); if you change to a new TXU Energy plan, the TXU Energy iThermostat will be compatible. However, there is a $150 fee if you opt out of the program before the 2-year term expires. If you move there is no cancellation fee. Under both scenarios, you can keep the TXU Energy iThermostat. However, if you opt out, you will no longer have access to the remote communicating feature of the TXU Energy iThermostat.

Cycling
Q. What does it mean to cycle my air conditioner?
A. When everyone's air conditioner runs at the same time on our hottest summer days, it can create too much demand on the state's electricity supply. Cycling air conditioners on and off lets us stagger use, which reduces the strain on transmission facilities so everyone has the electricity they need to keep their homes comfortable. Of course, you have ultimate control and can easily override a cycle period from any Web-enabled device or by calling1-866-733-1807.

Q. When will my air conditioner be cycled?
A. Your air conditioner will be cycled no more than 10 to 15 minutes out of any half-hour period when there's a strain on the power systems. Typically, such an event might occur on weekday afternoons during the months of May through September. You should not expect the cycle periods to happen on weekends or holidays since system usage is usually lower during these times.

Q. Will cycling my air conditioner damage it?
A. No, cycling your air conditioner will simply control the thermostat and briefly adjust the temperature setting. When the short cycling period ends, the thermostat will automatically adjust to your pre-determined settings. This is no different than when you manually adjust the thermostat and it will not damage your HVAC system.

Q. What are the expected changes in indoor temperature during air conditioner cycling?
A. You may not even notice that your air conditioner has been cycled. The cycling period will not last longer than 10 to 15 minutes during a half hour period. So in most cases, the temperature in your home may increase only three degrees. Once the cycling period ends, your home will return to its pre-set condition and temperatures
Back to top | Back to section top
Q. How will I know that my air conditioner is being cycled?
A. A message will be sent to the thermostat digital display approximately one hour before the cycling period begins to notify you of an upcoming event. During the event, the digital display will indicate that the thermostat is in a control mode.
