Thermostats control the heating and cooling of homes. Programmable thermostats allow the residents of a house to change the temperature settings at night and during the day, when they stay home or when they leave home for work. Programmable thermostats help reduce the overall energy consumption.
A conventional digital thermostat regulates the house heating system at one temperature. For example, if you set the thermostat at 20 ° C (68 ° F) during the winter, the heater will activate when the inside temperature drops below 20 ° C and stop when the temperature house air exceeds 20 ° C.
A programmable thermostat contains an electronic clock. It can automatically lower the temperature setting at night when you sleep or during the day when you are at work. It can also reduce the temperature to a more comfortable level before you wake up or before you arrive home from work. This way, you can save energy by setting the thermostat lower without experiencing any discomfort while the house warms up.
In the case of an air conditioning system, the programmable thermostat can be used to raise the temperature. It then allows the house to warm up in your absence and return to a comfortable room temperature before you return.
What can go wrong?
Several problems can arise with programmable thermostats:
The first problem is related to the level of discomfort. One can be really uncomfortable if the house is cold during the winter. Parts of the house will be colder if you set the thermostat to restore the temperature to 20 ° C or 22 ° C (68 ° F or 71 ° F). This applies even if you schedule a daily drop in temperature after you leave for work, but you go home earlier than expected.
A lowering of the programmed temperature is ideal for people whose work periods and sleep are predictable. If your schedule is completely unpredictable, it would probably be easier to lower the temperature before going to bed or leaving the house using a programmable thermostat.
