Final answer:
Line voltage thermostats, also known as high-voltage thermostats, can usually switch the high voltage on and off to control the operation of heating or cooling equipment in HVAC systems.
Step-by-step explanation:
Line voltage thermostats, also known as high-voltage thermostats, can usually switch.
They are designed to handle the higher voltage typically found in electrical systems used for heating, ventilation, and air conditioning (HVAC) in residential and commercial buildings.
These thermostats are capable of switching the high voltage on and off to control the operation of heating or cooling equipment.
