1. A thermal control system, comprising:
a housing defining an intake flow path for travel of intake airflow and an exhaust flow path for travel of exhaust airflow;
an intake door disposed in the housing along the intake flow path, the intake door having a first position blocking the intake airflow from passing through the intake door and a second position allowing the intake airflow to pass through the intake door;
an exhaust door disposed in the housing along the exhaust flow path, the exhaust door having a first position blocking the exhaust airflow from passing through the exhaust door and a second position allowing the exhaust airflow to pass through the exhaust door; and
a mode door disposed in the housing between the intake flow path and the exhaust flow path, the mode door having:
a first position blocking the intake airflow from passing through a heat exchanger and allowing the exhaust airflow to pass through the heat exchanger;
a second position blocking the exhaust airflow from passing through the heat exchanger and allowing the intake airflow to pass through the heat exchanger; and
a third position allowing the intake airflow and the exhaust airflow to pass through the heat exchanger,
wherein the housing is configured such that when the intake door is in the second position and the mode door is in the first position, the intake airflow bypasses the heat exchanger, and
wherein the housing is further configured such that when the exhaust door is in the second position and the mode door is in the second position, the exhaust airflow bypasses the heat exchanger.
