Abstract
A temperature control system that includes a sensor, a variable speed blower, and a controller. The controller is configured to receive an air temperature measurement from the sensor and determine a temperature value based on the received air temperature measurement. The controller is further configured to compare the determined temperature value to a first threshold value and a second threshold value and to operate the variable speed blower based on the comparison. The controller is configured to set the variable speed blower to a first fan speed when the temperature value is below the first threshold value and to a second fan speed when the temperature value is above the second threshold value. The controller is further configured to set the variable speed blower to a third fan speed that linearly correlates with temperature when the temperature value is between the first threshold and the second threshold.
