What happens when a room exceeds the upper temperature setting of a thermostat controlling a check damper?

• A. The damper is closed
• B. The damper opens to admit more air
• C. The system shuts off the heating
• D. The thermostat is reset

Answer: (B)

When a room exceeds the upper temperature setting of a thermostat controlling a check damper, the correct response is that the damper opens to admit more air. This action is part of a temperature control strategy designed to manage airflow and temperature effectively. When the room temperature surpasses the set threshold, it indicates that the space is becoming too warm, and in order to help cool it down, the damper must open. By allowing more air into the room, typically from a cooler source, the system can help to lower the temperature more effectively. This process improves comfort by promoting better air circulation, reducing hotspots, and allowing for the introduction of cooler air which aids in re-establishing the desired temperature range. The other options describe different potential scenarios. For example, closing the damper would restrict airflow, potentially leading to higher temperatures rather than cooling. Shutting off the heating system wouldn't be appropriate if the goal is to cool the space or provide adequate airflow. Resetting the thermostat may not be necessary if the system is functioning correctly and adjusting as needed based on the exceeding temperature. Thus, allowing the damper to open is the correct response to manage the temperature effectively.
