In the illustrated terminal reheat multiple zone system, what statement represents the functioning of the summer outside air duct thermostat? Illustration GS-RA-42 Illustration GS-RA-42: the U.S. Coast Guard has not released this illustration.

Correct Answer: Option C — During the cooling season, the summer thermostat senses the outside air temperature and closes the exhaust and outside air dampers when the outside air temperature is significantly higher than typical indoor air temperatures.

During high outside air temperatures, sensible heat loads dictate closing outdoor and exhaust dampers to minimize energy consumption and rely primarily on recirculated conditioned air.
