4.3 Delayed Start
With the M720 controller it is possible to define a delayed start. If this menu item is chosen, the
screen for entering the start delay will be displayed.
In this screen the number of hours and minutes delay can be entered. Changing values can be
done with the N
UMERIC keys and with the P LUS and M INUS buttons. Changing the cursor to
another edit field can be done with the A RROW U P and/or A RROW D OWN buttons. Confirming a
value must be done with the E NTER key.
If the E NTER key is pressed when the cursor is on the minute field, the delayed start will be ac-
tivated and the overview screen will be activated again. If both the number of hours and the
number of minutes are set to 0, the delayed start timer will be preset to 30 seconds, which is the
minimum time for a delayed start. The maximum time adjustable for a delayed start is 11 hours
and 59 minutes.
In the overview screen, the message D ELAYED S TART I N : will be displayed, followed by the time
until the machine will start in HH:MM:SS format.
The dryer will count down until the delayed start time displayed is 0, and then it will start the
selected program. For safety reasons, the beeper will sound 5 seconds before the machine starts.
If delayed start is activated, and a program cycle is started manually, the delayed start will be
canceled. Canceling the delayed start can also be done with the S
TOP key.
