What is a Thermostat? |
|
Answer:
A thermostat is a device used to control heating or cooling equipment A thermostat contains either electronic or mechanical components which, in essence, monitor building temperatures; and when temperatures vary beyond prescribed setpoints, the thermostat sends a signal to the system equipment to provide either heating or cooling, whichever is needed. Simple thermostats often have a bi-metallic coil that shrinks and grows as temperatures fluctuate. Incorporated along with this "moving coil" is either a tilting mercury switch, or trip points, which trigger a signal to the equipment. Modern, high-technology programmable thermostats are a little more complex, and probably a lot more effective; not only at controlling temperatures, but in energy optimization as well, through sensible programming of run-times and temperature setpoints.
