It’s amazing how a small device like a thermostat can have such a large impact on your comfort. Although your furnace or heat pump does the work of generating or moving heat to provide you with the warmth you need during frigid days, without the thermostat nothing would happen—or whatever happens wouldn’t be what you want to happen. Thermostats are quite powerful devices, and making sure that the units in your home work correctly is a vital part of getting the most out of your heating system.
If you want to increase the efficiency and effectiveness of your heating system in The Woodlands TX, consider a thermostat replacement that will upgrade you to a programmable or wi-fi model. To learn more about your options for thermostats, contact Kingwood Air Repair.
How thermostats operate
At the very basic level, a thermostat is a combination of switches and a heat sensor. How these switches and sensors work varies from model to model (manual thermostats use two switches to move metal balls that make contact between circuits inside the thermostat), but it’s important to remember that a thermostat operates as a switch, not a throttle. This means that raising the temperature on a thermostat will not make your heater produce heat faster; it will keep it on longer… until the thermostat senses with its heat anticipator that the temperature is about to reach its setting. Remember this, because it can save you money on your heating bills; you don’t need to push the thermostat all the way up to get sufficient heat.
The electrical wiring on a thermostat consists of five wires. Two come from the transformer on the heating system and the cooling system respectively. The next two come from the relays that turn on the heating system and cooling system respectively. The fifth comes from the relay that turns on the fan. (Another important fact to remember: the fan operates independent of the other systems.) The transformers provide the thermostat with the power to turn on the relays, and relays then turn on the power to the two systems and the fan as needed.
How is the heat sensed? Digital thermostats use a device called a thermistor. This component measures electrical resistance from the change in temperature, and a microcontroller then converts that resistance into a temperature reading for the thermostat’s system.
