Which instrument would you use to monitor temperature within a building or building zone?

• A. Thermostat
• B. Hygrometer
• C. Anemometer
• D. Barometer

Answer: (A)

Monitoring temperature in a building or zone relies on a device that both senses the air temperature and drives the HVAC system to maintain the desired level. A thermostat does this by including a temperature sensor and a control mechanism that compares the actual temperature to the setpoint and triggers heating, cooling, or fan operation as needed. In building automation, it can be a standalone unit or part of a larger network to keep a space comfortable and energy-efficient. The other options measure humidity, airflow, or atmospheric pressure, which are valuable for other purposes but not for regulating temperature in climate control. So the instrument used to monitor temperature in a building or zone is the thermostat.
