A method utilizing a controller for controlling the operation of a zoned climate control system including a primary heat source, a secondary heat source, a cooling unit, and a humidifier unit. The controller is configured to receive both heating demand signals and cooling demand signals from a plurality of zone thermostats positioned throughout the residence. Upon receiving a heating demand signal, the controller operates the primary heat source to provide heat to the zone issuing the heating demand signal. The primary heat source is a radiant heating system. The controller determines whether the primary heat source satisfies the heating demand signal within a maximum heating period. If the heating demand is not satisfied within this period, the controller activates the secondary heat source to supplement the heat being supplied by the primary heat source. The secondary heat source is a forced air HVAC system which also includes the cooling unit.

The heat sink recited in claim 1, wherein each fin of said plurality of heat conducting fins also includes an outer air blade projecting upwardly from said back face thereof so as to extend above said front face, said outer air blade guiding the supply of fan air for receipt through said air intake opening at the top of said fin into said air exhaust cavity located between the front and back faces of said fin. 9. A heat sink to dissipate heat generated by a source, said heat sink comprising a core including a plurality of adjacent heat conducting fins to collect the heat generated by the source, a support plate located between said core and the source of heat, and tie-down straps surrounding said core and connected to said support plate so as to hold said core against said support plate, and wherein each fin of said plurality of adjacent heat conducting fins having a front face, the bottom of said front face having a curved force-distributing edge aligned to engage the support plate against which said core is held, a back face, open opposite sides, an air exhaust cavity located between said front and back faces and extending laterally between said open opposite sides, a top connected between said front and back faces, and an air intake opening extending vertically through said top for receiving a supply of fan air therethrough and communicating with said laterally extending air exhaust cavity, said vertically extending air intake opening and said laterally extending air exhaust cavity of each fin of said plurality of adjacent heat conducting fins forming non-linear air flow paths through said core by which the heat generated by the source is transferred through said support plate to be collected by said plurality of adjacent heat conducting fins and blown by the fan air into the atmosphere through the open opposite sides of said fins. 10. The heat sink recited in claim 8, wherein said vertically extending air intake opening and said laterally extending air exhaust cavity of each fin of said plurality of adjacent heat conducting fins are aligned perpendicularly relative to one another. 11. The heat sink recited in claim 9, wherein said air exhaust cavity that is located between the front and back faces and extends laterally between the open opposite sides of each fin of said plurality of adjacent heat conducting fins has a triangular shape. 12. The heat sink recited in claim 11, wherein the bottoms of said front and back faces of each fin of said plurality of adjacent heat conducting fins engage one another so as to establish said triangular air exhaust cavity that is located between the front and back faces and extends laterally between the open opposite sides of said fin. 13. The heat sink recited in claim 9, wherein each fin of said plurality of adjacent heat conducting fins also has an inner air blade cut from said front face thereof and bent rearwardly towards said back face so as to lie within said air exhaust cavity that is located between said front and back faces and extends laterally between the open opposite ends of said fin. 14. The heat sink recited in claim 13, wherein each fin of said plurality of adjacent heat conducting fins also has an opening in said front face thereof, said opening formed by said inner air blade being cut from said front face and bent rearwardly towards said back face, a portion of the supply of fan air received through said air intake opening at the top of said fin being intercepted by said inner air blade and diverted to the adjacent one of said plurality of adjacent heat conducting fins by way of said opening. 15. The heat sink recited in claim 14, wherein each fin of said plurality of adjacent heat conducting fins also includes a base projecting outwardly from the bottom of the front face thereof so as to engage the back face of the adjacent fin to thereby establish a supplemental air exhaust cavity between the front face and the back face of the pair of adjacent fins, whereby said portion of fan air that is intercepted by said inner air blade is diverted into said supplemental air exhaust cavity to be exhausted to the atmosphere. 16. The heat sink recited in claim 9, wherein each fin of said plurality of adjacent heat conducting fins also includes an outer air blade projecting upwardly from said back face thereof so as to extend above said front face, the supply of fan air being blown between the outer air blades of a pair of adjacent fins for receipt through the air intake opening at the top of one of said pair of fins. 17. A heat sink to dissipate heat that is generated by a source, said heat sink comprising a core including a plurality of adjacent heat conducting fins to collect the heat generated by the source, each fin of said plurality of adjacent heat conducting fins having a front face, an air transfer opening formed through said front face, a back face spaced from said front face, a top connected between said front and back faces, an air intake opening formed through said top to receive a supply of fan air therethrough, a primary air exhaust cavity lying between said front and back faces and extending from said air intake opening to the atmosphere, and a supplemental air exhaust cavity lying between the front face of a first of said plurality of heat conducting fins and the back face of an adjacent fin, such that a first portion of the supply of fan air received through the air intake opening at the top of said first fin is delivered to said primary air exhaust cavity and the remaining portion of the supply of fan air received through said air intake opening is delivered to said supplemental air exhaust cavity by way of said air transfer opening formed in the front face of said first fin. 18.
