Possible Cause: PID loop requires adjustment.
Corrective Action: A technician familiar with adjusting PID loops should adjust the relevant PID loop in Technician Menu/Operation/PID Settings.

Corrective Action: Sensors placed in inappropriate locations (for example, temperature sensors too close to heaters or static pressure sensors on branch ducts) may cause hunting. Refer to Sensor Installation and Sequences for more information.
