" How It Works
Thermostat Controller manipulates the setpoints of the controlled thermostat to control its operation. This usurps most of the functionality of the controlled thermostat. To call for cooling, for example, Thermostat Controller will set the cooling setpoint of the controlled thermostat to a level well below the current temperature, thus forcing the controlled thermostat into cooling operation. The amount by which the setpoint is set below is determined by the Control Offset, a settable number of degrees. When the demand for cooling has been met, the controlled thermostat's cooling setpoint will be set well above the current temperature, thus forcing it to idle, and again using the Control Offset. The Control Offset defaults to 2° F, and should be set high enough to cover any difference between the average temperature of all of the sensors, and the temperature reported by the controlled thermostat itself."
