1. A method of controlling operation of a zoned climate control system having a primary radiant heating system and a secondary forced air heating system, the zoned climate control system having a plurality of individual zones each having a zone thermostat, the method comprising the steps of:

  • monitoring for the generation of a heating demand signal from any one of the zone thermostats;

    upon generation of a heating demand signal from any one of the zone thermostats, opening a zone valve for the individual zone generating the heating demand signal to provide heat from the primary radiant heating system to the individual zone generating the heating demand signal;

    monitoring the duration of time that heat is supplied to the individual zone demanding heat by the primary radiant heating system;

    comparing the duration of time that heat is supplied from the primary radiant heating system to the individual zone demanding heat to a predetermined maximum heating period;

    opening a zone damper for the individual zone generating the heating demand signal to provide heat from the secondary forced air heating system to the individual zone demanding heat when the duration of time that heat is supplied to the individual zone demanding heat by the primary radiant heating system exceeds the maximum heating period.
