Lighting controls will help reduce energy by:

  • Reducing the amount of power used during the peak demand period by automatically dimming lights or turning them off when they are not needed
  • Reducing the number of hours per year that the lights are on
  • Reducing internal heat gains by cutting down lighting use, which allows for reduced HVAC system size and a reduction in the building's cooling needs
  • Allowing occupants to use controls to lower light levels and save energy

Solar Air Heating - You Can Cut Utility Costs and Save Money


Solar energy is becoming very quickly recognized as one of the best alternatives to fossil fuels It is an abundant and renewable natural resource. It can be used to save energy in residential, commercial, and industrial settings. Solar technologies will use the sun's energy to provide heat, hot water, light, electricity, and cooling, for homes, businesses, and industry.

Many major advancements have been made in the solar technology fields over the recent years. Solar air heating is becoming more attractive than ever before now that it is becoming lower in cost and more efficient. Solar energy is easily the cleanest and most inexhaustible of any of the known energy sources. The many variations in energy prices have fueled interest in alternative fuels such as solar energy. Demand for solar energy has been increasing exponentially as heating, cooling and many other energy costs continue to skyrocket.

Solar air heating and solar water heating are two examples of solar thermal technologies which produce heat, but not electricity. Solar air heat is best suited for installation in new construction and existing houses. Solar panels for any type of heating should be placed on a south-facing pitched roof, free of shade. The angle should be between 20 and 50 degrees. They may also be mounted on an angled frame on the ground or on a flat roof. Solar air collectors (the devices that heat up the air using solar energy) can directly heat individual rooms. They also can potentially pre-heat the air passing into a heat recovery ventilator or the air of an air-source heat pump. Solar heating panels can be one of the most cost effective ways to reduce your utility bills. This will make a positive contribution towards a better environment. Solar air heating systems often use large bins filled with rocks that store heat (although this method is becoming rare due to problems associated with controlling moisture and mold growth in the rock).

Energy Policy Act has implemented a 30% tax credit for consumers who chose to install solar water heating systems. State and local government programs are now being put in place to encourage the use of solar energy. Cash incentives are available for those that integrate solar energy technology as an alternative energy source. The Department of Energy (DOE) is working to design even more cost-effective solar heating systems and to improve the longevity of the materials used in those systems. Other incentive programs now include offering homeowners tax credits for solar panel installations and for solar heating systems. With solar power you will save money, increase your property value, help protect the environment and help to create a more secure America by reducing our dependence on foreign energy fuel sources.

A great solar heating system will save energy, reduce utility costs, and produce clean energy.

Air Conditioning Programmable Thermostats - Great for Heating and Cooling


Programmable thermostats contribute to overall system performance, maximizing energy savings while providing complete comfort control. They also allow flexibility to homeowners because they can be programmed to match their lifestyle. Programmable thermostats save energy by turning down the cooling and heating system at night or at times when your home is typically unoccupied.


Did you know that properly using a programmable thermostat in your home is one of the easiest ways you can save energy, money. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings. They can achieve significant energy and money savings that are possible through the proper use of your programmable thermostat. Programmable thermostats do two things:
(1) Compare the thermometer reading of a room's temperature to the "ideal" thermostat temperature you select.

(2) Give start-and-stop commands to the heating or cooling system in order to achieve an indoor temperature that is as close to your "ideal" thermostat setting as possible.


Your savings will largely depend on the length of your energy saving program periods and the temperatures set. For example, an energy saving period of 10 hours with the temperature set back 10° will save more than a 5 hour energy saving period with the temperature set back 5°. By maintaining the highest or lowest required temperatures for four or five hours a day instead of 24 hours, a programmable thermostat can pay for itself in energy saved within four years.

A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home. The precise temperature control of a programmable, energy-saving thermostat saves wear and tear on high-efficiency heating and cooling equipment by properly cycling the equipment. A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home.


Controlling your heating more effectively could save you up to 17% on your heating costs. In fact, during the winter you can save about 3 percent of your heating costs for every degree you lower your thermostat. Begin lowering your heating bill immediately with the pre-programmed 7-day schedule, or modify the programming to suit your lifestyle. By delivering the heating or cooling when you need it, and optimizing temperature for activity, sleep and times you are away you can maximize your comfort level and save energy.

How to do energy saver dimming ?


Most modern dimmers provide normal energy savings. They reduce the total amount of watts consumed on the circuit. Many years ago, dimmers only reduced the watts consumed as light - making up the difference as heat in the dimmer switch. A 100W light turned down to 1/2 wattage at a dimmer switch resulted in 50 watts of light at the bulb, but 50 watts of heat was created in the switch. That was zero energy savings. The newer electronic dimmers will still let 50 watts be used as light, but only a few watts as heat in the switch.

To maximized energy savings, use of new cold cathode technology lights such as CFL (compact fluorescent lamp), LED (Light Emitting Diode), etc. types are suggested. You can use these lamps on a dimmer to furrther reduce the amount of energy used - but only if the lamp indicates that it is dimmable.

If the lamp or fixture does not specifically state it can be used on a dimmer, don't. This includes powering a light through a dimmer that is set to maximum brightness. Use a standard non-dimming switch instead.

I hope this helps & good luck!

Superswitch programmable wall light switch - when timer is in off position lights glow dim when using energy saving bulbs.


http://www.intermatic.com/products/timers/consumer%20indoor%20timers/in-wall%20timers/ej351c.aspx

Manual say 'incandescent' light bulbs only.

What can I control with my EJ351C? The EJ351C timer is to be used with standard base incandescent light bulbs only! It should not be used to control lighting such as:
  • Compact Florescent
  • Energy Saver
  • Flood lights
  • Halogen
  • Mercury Vapor
  • Christmas lights
  • Candelabra bulbs

The EJ500C is designed only for standard incandescent lights, not chandelier bulbs, CFLs, etc. Replace it with the ST01C, and you'll be fine. Intermatic may even exchange it for you if you if you complain to them.

Crescent light on


Usually it means "go to sleep" (the crescent is intended to be a moon and mean "night"). It won't work unless you have the appropriate energy saving profile activated in the system, though (Control Panel -> Energy Saving)
