Next Generation Lux Products TX9. TS Universal 7 Day Programmable Touch Screen Thermostat. A programmable thermostat is a thermostat which is designed to adjust the temperature according to a series of programmed settings that take effect at different times of the day. Programmable thermostats may also be called setback thermostats or clock thermostats. BenefitseditHeating and cooling losses from a building or any other container become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable. For example, during cooling season, a programmable thermostat used in a home may be set to allow the temperature in the house to rise during the workday when no one will be at home. It may then be set to turn on the air conditioning before the arrival of occupants, allowing the house to be cool upon the arrival of the occupants while still having saved air conditioning energy during the peak outdoor temperatures.

Conversely, during the heating season, the programmable thermostat may be set to allow the temperature in the house to drop when the house is unoccupied during the day and also at night after all occupants have gone to bed, re heating the house prior to the occupants arriving home in the evening or waking up in the morning. Since most people sleep better when a room is cooler and the temperature differential between the interior and exterior of a building will be greatest on a cold winter night, this reduces energy losses. Similar scenarios are available in commercial buildings, with due consideration of the buildings occupancy patterns. According to Consumer Reports magazine, programmable thermostats can reduce energy bills by about 1. ControversyeditWhile programmable thermostats may be able to save energy when used correctly, little or no average energy savings has been demonstrated in residential field studies. Difficulty with usability in residential environments appears to lead to lack of persistence of energy savings in homes. According to the US EPA regarding residential programmable thermostat, Available studies indicate no savings from programmable thermostat PT installation. Some studies indicate slight increased consumption. This is supported with studies by Nevius and Pigg,3 Cross and Judd4 and others and Peffer et al. In addition to potential increased energy consumption, digital programmable thermostats have been criticised for their poor usability. Several studies have found that digital programmable thermostats are difficult for users to programme6 and older people in particular can struggle to use them see Combe et al. If the desired energy savings are to be achieved by these types of products then systems need to be simple, intuitive and effective to use by a wide range of people. Construction and featureseditClock thermostatseditThe most basic clock thermostats may only implement one program with two periods a hotter period and a colder period, and the same program is run day after day. More sophisticated clock thermostats may allow four or more hot and cold periods to be set per day. Usually, only two distinct temperatures a hotter temperature and a colder temperature can be set, even if multiple periods are permitted. The hotter and colder temperatures are usually established simply by sliding two levers along an analogue temperature scale, much the same as in a conventional non clock thermostat.

This design, while simple to manufacture and relatively easy to program, sacrifices comfort on weekends since the program is repeated each of the seven days of the week with no variation. To overcome this deficit, a push button is sometimes provided to allow the user to explicitly switch once the current period from hot period to a cold period or vice versa the usual use of this button is to over ride a set back that takes place during the workday when the home is normally unoccupied. The clock mechanism is electrical. Two methods have commonly been used to operate it 1 A separate, continuous source of 2. VAC is provided to the thermostat. A rechargeable battery in the thermostat operates the clock. This battery charges when the thermostat is not calling for heat and 2. VAC is available to it. It discharges to operate the clock when the thermostat is set for heating or cooling. Digital thermostatsedit. A touch screen programmable thermostat in programming mode. Digital thermostats may implement the same functions, but most provide more versatility. For example, they commonly allow setting temperatures for two, four, or six periods each day, and rather than being limited to a single hotter temperature and a single colder temperature, digital thermostats usually allow each period to be set to a unique temperature. The periods are commonly labeled Morning, Day, Evening, and Night, although nothing constrains the time intervals involved. Digital thermostats usually allow the user to override the programmed temperature for the period, automatically resuming programmed temperatures when the next period begins. A function to hold lock in the current temperature is usually provided as well in this case, the override temperature is maintained until the user cancels the hold or a programmed event occurs to resume the normal program. More sophisticated models will allow for the release of the hold to take place at a set time in the future. As with clock thermostats, basic digital thermostats may have just one cycle that is run every day of the week. More sophisticated thermostats may have a weekday schedule and a separate weekend schedule so called 5 2 setting or separate Saturday and Sunday schedules so called 5 1 1 settings, while other thermostats will offer a separate schedule for each day of the week 7 day settings. The selection of which days are defined as the weekend is arbitrary, depending on the users heating and cooling schedule requirements. Fender Guitar Serial Numbers Search. Often, a manufacturer will sell three similar thermostats offering each of those levels of functionality, and there is no obvious difference in the thermostats other than the factory programming and the price. Most digital thermostats have separate programs for heating and cooling, and may feature a digital or manual switch to turn on the furnace blower for air circulation, even when the system isnt heating or cooling. More sophisticated models may be programmed to run the circulating fan for a brief 5 to 1. This is particularly useful in buildings subject to stratification where without frequent air circulation, hot air rises and separates from the cooler air that falls. Digital thermostats may also have a user programmable air filter change reminder this counts the accumulated run time of the heatingcooling system and reminds the user when it is time to change the filter. The feature often displays the accumulated run time either as an aggregate of both heating and cooling or displaying each time separately. Some digital thermostats have the capability of being programmed using a touch tone telephone or over the Internet, such as the Nest Learning Thermostat.
