Thermostat
Thermostats regulate temperature and humidity in homes and commercial buildings. Newer models incorporate touch
screens, 7-day programmability and wireless communication to remote sensors to simplify and improve heating and cooling.
Thermostats may also support a Home Area Network (HAN) that provides access to time-of-day billing rates from public
utilities and the ability to schedule the use high-load equipment at lower rates.
