A multiple heating / cooling zone control system is disclosed. A heating / cooling system control device continuously monitors heating / cooling zone demand and matches the heating / cooling device output capacity to the total space or heat input required. Within the calculated heating / cooling device output capacity the heating / cooling device is modulated based on zone temperature setpoint to further adjust heating / cooling device output. As heat / cooling loss is increased heating / cooling device capacity and modulation are increased. Should heat / cooling loss decrease heating / cooling device capacity and modulation are decreased. Since heat / cooling output is adjusted based on the heat loss(gain) the heating / cooling device can be immediately adjusted to the proper or matching heating / cooling rate even before water / air temperature based adjustments can be made. Hence, the overall effect of the control device is a reduction in cycles of the heating / cooling device and the life of the heating / cooling device is extended and subsequent energy is saved.
