Question 215General Subjects - 1st Asst/Chief

The correct answer is 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. This is correct because the purpose of the summer outside air duct thermostat is to minimize the amount of hot outside air being brought into the building during the cooling season. When the outside air temperature is higher than the desired indoor temperature, the thermostat will close the dampers to reduce the amount of hot outside air entering the system, which helps maintain the desired cooling effect. The other options are incorrect because they either describe the opposite function (opening the dampers instead of closing them) or refer to the inside air temperature instead of the outside air temperature, which is not the role of the summer outside air duct thermostat.
