*If you select AutoTune for any zone and press Enter, the AutoTune process for that zone begins. The control will
heat and monitor that device to automaticall determine the correct PID values. This process takes from 5 to 40 min-

NOTES:
D If set points are entered in Celsius and the readout is later changed to Fahrenheit, the set points are automati-
cally converted.
