controller will operate according to the new parameter settings. The
controller does not display a current day greater than 99 even if it contin-
ues to operate with the current parameter settings.
Set the selection knob to PROGRAM. The current day number
flashes on the display.
Use the adjustment knob to adjust the current day number.
