A trim module having a first heat exchanger; a second heat exchanger; and a thermoelectric cooler (TEC) module thermally coupled between the heat exchangers; a mix manifold conduit fluidly coupled to the inlet of the first heat exchanger; a zone supply conduit fluidly coupled to the outlet of the first heat exchanger; a cabin return conduit fluidly coupled to the inlet of the second heat exchanger; an exhaust conduit fluidly coupled to the outlet of the second heat exchanger, wherein the TEC module is configured to operate in a first mode or a second mode, depending on a temperature within the zone supply conduit and a target temperature, and in the first mode, the TEC module transfers thermal energy from the first heat exchanger to the second heat exchanger; and in the second mode the TEC module transfers thermal energy from the second heat exchanger to the first heat exchanger.
