Final answer:
Line voltage thermostats typically operate on a voltage range of 120 to 480 volts and are commonly used in electrical systems to control heating or cooling based on the current voltage level.
Step-by-step explanation:
Line voltage thermostats typically operate on a voltage range of 120 to 480 volts. This type of thermostat is commonly used in electrical systems to control heating or cooling based on the current voltage level. For example, if the voltage drops below a certain threshold, the thermostat may activate the heating system to raise the voltage back to the desired level.
One important consideration when using line voltage thermostats is safety. Since line voltage thermostats operate at higher voltages, they may require additional precautions and safety measures to prevent electrical shocks or other hazards.
