Pushing the E NTER key without the S HIFT key (see item 10) means enter or accept. If the key
is pressed in combination with the S HIFT key (see item 10), is becomes the C LEAR function.
The E NTER key is used to confirm a choice or an adjustment. For example, if another program
is selected from the list, the E NTER key must be pressed to confirm the choice. This is the
same when a parameter value is changed. When a new value is entered, this value must be
confirmed with the E
NTER key, otherwise the change in value will not be stored.
The C LEAR key is used to cancel an entered value. For example, when a parameter has been
changed in error, pressing the C LEAR key cancels the change. If the E NTER key is pressed in
combination with the S HIFT key, the old parameter value will be restored.
10. S HIFT key
This key is used to access the secondary function of a key. When a key is pressed without
the S
HIFT key, it functions normally, as indicated in white on the key. If a key is pressed in
combination with the S HIFT key, the secondary function is activated, indicated by function in
the same color as the S HIFT key. To use the secondary function of a key, first push the S HIFT
key, then push the key itself while holding the S HIFT key. Release the key then release the
S HIFT key.
11. Numeric keypad
These buttons can be used to enter a numeric value. For example in the program selection
screen a program number can be entered with these buttons. Entering a new parameter value
and entering a password can also be done with these buttons.
The numeric keypad buttons are also used for editing the name of a program. In this case
they are used to enter characters (see Section 4.5.2 on page 25).
12. Temporary temperature set-point change
Sometimes it is necessary to manually adjust the temperature to a higher or lower set-point.
If the S
HIFT key (see item 10) is pressed in combination with the INCREASE TEMPERA-
TURE ( ) key, the current temperature set-point will be increased by 5 degrees Fahrenheit
(or 2.8 degrees Celsius). If the S HIFT key (see item 10) is pressed in combination with the
DECREASE TEMPERATURE key ( ), the current temperature set-point will be decreased
by 5 degrees Fahrenheit (or 2.8 degrees Celsius). The controller uses Fahrenheit units in-
ternally but the interface units are configurable as either Fahrenheit or Celsius. When the
interface temperature units is set to Fahrenheit increments of 5 degrees increase or decrease
will be displayed. When the interface temperature units is set to Celsius the display will
sometimes show an increment of 2 degrees and sometimes an increment of 3 degrees. This
is because 5 degrees Fahrenheit is equal to 2.8 degrees Celsius but DOES NOT influence the
actual increment, which is always 5 degrees Fahrenheit.
Please note that these changes in set-point are temporary. They do not change the pro-
grammed value in the active program. This means that the next time the program runs,
the temporarily changed values will be forgotten. Also, if a temporary change is made in
the drying cycle of the program, this does not influence the cool-down temperature setting
adjusted.
