27 New Honeywell Programmable Thermostats from DtiCorp.com

You can save as much as 33% a year on your heating and cooling bills using programmable thermostats.


Fort Lauderdale, FL - Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing 27 New Honeywell Programmable Thermostats. Using a programmable thermostat, you can adjust the times you turn on the heating or air-conditioning according to a preset schedule. As a result, the equipment doesn't operate as much when you are asleep or when the house, or a part of it, is not occupied. Programmable thermostats can store and repeat multiple daily settings (six or more temperature settings a day) that you can manually override without affecting the rest of the daily or weekly program.

Honeywell Programmable Thermostats provide the ability to automatically adjust for unique lifestyles, controlling home comfort to the desired temperature at the desired time. They do the work for the homeowner automatically when they are away or asleep. And the big benefit is energy savings - up to 33% on home heating and cooling costs - by adjusting the temperature up or down, thereby reducing equipment run-time.

ListFree.org - imageboard related to popular culture

Introducing http://www.ListFree.org – an imageboard related to popular culture.

Imageboards, similar to bulletin boards, are used for discussion of a variety of topics. The primary focus of imageboards, however, is directed away from text posts, and is instead placed on picture posts. The two share many of the same structures, including separate forums for separate topics, as well as similar audiences. Imageboards are much more transitory with content - on some boards (especially highly-trafficked ones), the thread deletion time can be as little as 10 minutes. The most popular English-language imageboards tend to revolve around Japanese culture such as CG artwork of anime. In Japan, where imageboards are more common, topics vary widely, ranging from trains to current news.

Imageboards are also different from online galleries in that most of the works posted are not made by the poster, but instead are taken from other online sources: galleries, other imageboards, and edited pictures.

Most imageboards and 2channel-style discussion boards allow (and encourage) anonymous posting and use a system of tripcodes instead of registration. Anonymity is considered to be one of the advantages of an imageboard. Some boards have from time to time removed the ability to post with a name altogether (known as 'forced anonymous/anonymity').

A tripcode is a means of telecommunication authentication that does not require registration. Tripcodes are most often used in 2channel-style message boards or Futaba Channel-style imageboards. A tripcode is a hashed password by which a person can be identified by others.
A tripcode is the result of input to a cryptographic hash function on the message board server, usually entered in the same field as the name. Readers of the board can identify postings made by the same user by comparing tripcodes. If two people use the same user name, they can be told apart because they, presumably, don't know each other's passwords that generate the different tripcodes. This way, the names and passwords don't have to be stored in a database. As many boards use the same algorithm, tripcodes are usually consistent.

If a user wants to reply to a thread but not bump it, they can put the word “sage” in the e-mail field. "Ageing" can refer to either bumping a post or putting the word age into the e-mail field. It is considered polite to sage when replying to your own thread.

In Japan, the imageboard is a much larger cultural symbol, with one estimate putting the total number of posts for Futaba's seven Nijiura boards at over 56,000,000 and rising.

About ListFree.org: ListFree.org (http://www.listfree.org) is an English language imageboard based around the posting of pictures related to popular culture and their discussion. Unlike most web forums, ListFree.org does not have a registration system, allowing users to post anonymously. Any nickname may be used when posting, even one that has been previously adopted, such as "Anonymous". In place of registration, ListFree.org has provided tripcodes as an optional form of authenticating a poster's identity. Tease your brain and make the most out of your time online based on content collaboration.

Honeywell-Thermostats.com – Service for buying Honeywell thermostats

Honeywell-Thermostats.com is a Shopping Assistance Service for customers buying HVAC thermostats. Our mission is to provide you with the best service to buy products from the brands you know and want. No one knows thermostats better than Honeywell. Their heritage is built on over 100 years of thermostat design and manufacturing. The primary job of a thermostat is to accurately control home temperature, and that is why Honeywell makes thermostats that are easy to use, contain high quality components and are engineered to precise design specifications resulting in pinpoint temperature control to +/- 1 F. The focus is on quality, performance and innovation, and it shows in the complete lines of brand new Honeywell thermostats.

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by switching heating or cooling devices on or off or regulating the flow of a heat transfer fluid as needed to maintain the correct temperature.

The Honeywell digital thermostats have no moving parts to measure temperature and instead rely on thermistors or other semiconductor devices such as a resistance thermometer (resistance temperature detector). Typically one or more regular batteries must be installed to operate it, although some so-called "power stealing" digital thermostats use the common 24 volt AC circuits as a power source, but will not operate on thermopile powered "millivolt" circuits used in some furnaces. Each has an LCD screen showing the current temperature, and the current setting. Most also have a clock, and time-of-day and even day-of-week settings for the temperature, used for comfort and energy conservation. Some advanced models have touch screens, or the ability to work with home automation or building automation systems.

Honeywell digital thermostats use either a relay or a semiconductor device such as triac to act as switch to control the HVAC unit. Units with relays will operate millivolt systems, but often make an audible "click" noise when switching on or off.

More expensive models have a built-in PID controller, so that the thermostat knows ahead how the system will react to its commands. For instance, setting it up that temperature in the morning at 7 a.m. should be 21°C, makes sure that at that time the temperature will be 21°C, where a conventional thermostat would just start working at that time. The PID controller decides at what time the system should be activated in order to reach the desired temperature at the desired time. It also makes sure that the temperature is very stable (for instance, by reducing overshoots).

Most Honeywell digital thermostats in common residential use in North America and Europe are programmable thermostats, which will typically provide a 30% energy savings if left with their default programs; adjustments to these defaults may increase or reduce energy savings.

HvacTotal.com - Information about HVAC Relays

An HVAC relay is a type of HVAC control system commonly used to monitor temperature, pressure, and humidity of large commercial and industrial facilities. HVAC controls, such as in building automation system, are significant in the optimal start programs. When the program calls for a warm-up, the central air handling systems of the plant would start and operate with a recirculation air of 100 percent. When it calls for a cool-down, the central air handling systems of the plant
would start and operate with
a return air of 100 percent.




An HVAC relay uses either one or perhaps more central controllers to regulate terminal unit controllers that are remote, communicating through an operator interface, usually one or more PCs. An HVAC relay is also often integrated with other systems such as smoke, fire, or light controls.




There are many types of HVAC relays available in the market. Temco Controls has actually three HVAC relays. Their MR3000 is a general-purpose mechanical relay and fits for both low voltage as well as excellent power switching. To activate it, it needs only 10-12 VDC (voltage direct current) at 100ma (milliampere) for its low-power coil. Its double-pole, double-throw (DPDT) relay is estimated to be at 10A (ampere). Each relay consists of LED that indicates
its voltage status. Its mechanical relay board is a slight modification of MR3000. They are actually two types of it: 4- and 8-gang versions. Its features are very similar to that of an ordinary MR3000 mechanical relay in the sense that it still has a low-power coil and possesses LED lights for each relays. Additional LEDs are used to monitor fuse loads. The mechanical board relay jumper can be set in two modes. It can be switched at 24 VAC on common ground, or you can use dry contact mode.




Temco Control SSR3000 features photo isolation of 4,000 volts and voltage turn-on, among others. It is a type of a solid-state relay. However, the word relay may be a misnomer as it is not a relay at all. It depends on electronics to do the actual switching. SSR3000 is known to provide solid-sate dependability for your HVAC systems.  For best performance, each relay is pretested before it is delivered.





Fujitsu Components America is one of the world leading manufacturers and distributors of electronic parts all throughout America. In 2004, it introduced and released into the market its newest type of HVAC relay called FTR-K3. It is a slim relay with a power of 20 amperes and an operating power of 780mW (milliwatts), the lowest of among its class. It has variety of uses, such as to switch compressor and inverter loads found in air conditioners and other appliances found in offices and in homes.  FTR-K3
is very durable and long-lasting, capable of 2 million operations (its mechanical life) or 100,000 operations (its electrical life) at its rated load.




Another leading company in the mechanical engineering industry is American Zettler. It boasts of being world no. 1 manufacturer and seller of HVAC relays. Its catalog or product list, which you can download, features over thirty kinds of relays for different purposes. Furthermore, each model has its own distinctive characteristic, allowing you to choose the best or the most appropriate for your need.




Omron has one of the best kinds of contactor relays. They consist of main contactors with an addition of contact blocks. Moreover, their components are finger proof and come in different sizes; definitely, you have almost infinite ways of possible configuration.




HVAC relays are sometimes manufactured as part of power packs. We can take, for example, Leviton occupancy sensors, which are the most highly developed, functioning sensors in the market. These sensors, along with its own built-in HVAC relays, can actually place all control connections in one central location.  Computers can also be used to control HVAC relay operations through an open- or closed-contact representation. This is because PCs use binary logic-either one or zero, yes or no, true or false-that
is transformed into electrical signals and eventually into true-or-false digital signals.

HvacNation.com – Information about HVAC Tools

HVAC tools

Getting the right HVAC tools and gauges is as important as having the right ingredients in cooking. Furthermore, utilizing the right tools is one big step in having the right system. Thus, it is advisable for HVAC practitioners, especially for beginners, to know what basic tools are currently used today.




One basic HVAC tool is the wrench. This device is used to tighten or loosen bolts (usually those with hex heads) and nuts. There are many kinds of wrenches: open-end, combination, adjustable open-end, flare nut. Most HVAC technicians prefer using the ratchet-type box wrench. They are excellent time savers as they immediately tighten or loosen around nuts and bolts. For refrigeration and air-conditioning systems, however, they go for the flare nuts. One note for you, though.  The best ones are those that
are made of alloy steel because they are tough. You also check the shape of the opening, see if they can easily hold and release nuts and bolts, as well as the grip.




For HVAC systems, you also need a screwdriver. To allow it to endure twisting torque, choose a screwdriver with tempered tips. Good ones are also with steel shafts. In using this tool, you have to remember some few things. First, a screwdriver can never replace a chisel or a pry bar. Select the most appropriate device needed at the moment. Second, it is necessary that you maintain the form of the screwdriver tip to avoid damage to the implement or injury to yourself.




Pliers are used to hold little objects or to bend or cut wires. Just like the other tools mentioned, there a variety of pliers available that come in different shapes and sizes. The most ideal for pipe work is the locking-type pliers (Vise-Grips). These pliers have the most effective holding power. Tension degrees are also adjustable. Pliers should never replace wrenches.




Another classic HVAC tool is the hammer, specifically a duct hammer. This is used when installing ducts and air distribution systems. Generally, its face is square and has a chisel-like back. In selecting the right hammer, its handle should be made of steel, wood, or fiberglass. Otherwise, more-than-enough pressure will bend or even break it.





A hacksaw can cut piping materials but not with the ones used for piping circuits that carry refrigerants. Other valuable tools are drills, meters, and gauges.




You can go to your nearest hardware store or shop online when purchasing HVAC tools. There is an extensive list of HVAC tools manufacturers and sellers that offer the best buys and quality products. HVACtool.com carries the widest range of HVAC products from various manufacturers like Amprobe, Fieldpiece, Maglite, to name a few.




Yet technology is starting to play a key role in the development of HVAC tools. There are already software programs available like Elite and Design-Build 6.0 that can do accurate load calculations and duct sizing, among others, without using any more hand tools. Furthermore, you can practically build your desired HVAC system from scratch, allowing you greater freedom to choose and identify other much-needed HVAC tools.




The truth is it is improbable and impossible to build something without anything to help you get by. In installing and even maintaining an effective and proper HVAC system, you need to have the right kinds of tools-that is, they are really useful in helping you implement your plan. And since they are the likely the same devices you are going to use in the future, you need to take care of them. They should always be cleaned and not utilized inappropriately. Handling them with care will not only make them long-lasting
but, it will also protect you from injury or accidents.
