Caution:
The controller is in the manual mode when the percent indi-
cator is lit or [P``~] appears in the most significant digit
of the lower display***. If the controller is in the manual
mode, the number displayed in the lower display is the
manual output power level. Setting this value can force an
output to stay on, regardless of the temperature reading. Al-
ways ensure you are in the automatic mode when adjusting
the temperature set point.
