The 5-2-1 Compressor Saver Starting up is the hardest time in the life of any type of electrical equipment. Ever notice that light bulbs almost always burn out when you first turn them on and not while they are on? This is due to the huge current that rushes in when a switch is thrown and power is first applied. Your air conditioner uses anywhere from 5 to 10 times more power on start-up than it does while running. With this burst of power comes a surge of heat that accompanies the electrical current. This heat damages the compressor, the terminals, the windings and run capacitor - all vital components of your air conditioner. The 5-2-1 Compressor Saver® protects these components by significantly reducing the amount of time it takes for your compressor to start - in some cases up to 50%. This means your air conditioner and compressor will bear ½ the stress, strain and heat each and every time it starts. Considering that your air conditioner may start up more than 6,000 times in a single cooling season, the positive impact that the 5-2-1 Compressor Saver® has on your air conditioner is significant. Before you replace your air conditioner, try adding a 5-2-1 Compressor Saver®. The 5-2-1 Compressor Saver® might save you from having to outlay thousands of dollars to buy a new air conditioner or compressor. At a fraction of the cost, installing the 5-2-1 Compressor Saver® is a wise investment

Manufacturer: Azel Technologies Inc. Brand: Azel Technologies Inc. Model: D-135E

The D-135E series thermostat is a stand-alone microprocessor based thermostat with large LCD display that takes the guess work out of reading the temperature. The D-135E maintains highly accurate temperature control without the programming hassle. The thermostat is designed to control room temperature by way of on/off controlling the heating (and cooling) equipments. The setpoint is displayed and can be changed easily by pressing up or down arrow button. This simple to use accurate thermostat will replace most round, square or rectangular thermostats. D-135E is environmentally safe, mercury-free which requires no leveling, so there's no hassle, and no special disposal requirements. This thermostat requires three or four wires to operate.
