ABSTRACT:
The temperature of the air leaving a heating coil is monitored for rising above a first threshold temperature value. An offset value is calculated for use in the positioning of each damper associated with a zone that is to be heated by air leaving the heating coil when the temperature of the air leaving the heating coil rises above the first threshold value. The offset value for each damper position is maintained until the temperature of the air leaving the heating coil drops below a second threshold temperature lower than the first threshold temperature. Any additional heating sources which also heat the air flowing over the heating coil are turned off immediately if the temperature of the air leaving the cooling coil rises above a third threshold value that is higher than the first threshold value.
