1. A method, comprising:

  • receiving data, including a target temperature for a zone, an actual temperature of the zone, and an ambient temperature of air being supplied to the thermal comfort system;

    initializing a regression model by;

    setting a coefficient to zero; and

    entering a heating rate of the thermal comfort system;

    determining, through the regression model, from the received data, a calculated time when the zone will reach the target temperature upon operation of the thermal comfort system;

    wherein the calculated time when the zone will reach the target temperature is defined by;


    tpred=(TaT

    p3+p4,tpred is the calculated time when the zone will reach the target temperature;

    taT is the target temperature for the zone;

    Ta is the actual temperature of the zone;

    To is the ambient temperature of air being supplied to the thermal comfort system; and

    p1, p2, p3, and p4 are coefficients of the regression model;

    solving for the calculated time when the zone will reach the target temperature in order to obtain an initial calculated heating time for the zone to reach the target temperature;

    operating the thermal comfort system for the initial calculated time when the zone will reach the target temperature.
