OPERATING AND PROGRAMMING INSTRUCTIONS
8-12
The enter button is used to confirm a choice or an adjustment. For example, if another
program is selected from the list, the enter button must be pushed to confirm the choice. This is the
same in case a parameter value is adjusted. When a new value is entered, this value has to be
confirmed with the enter button, otherwise the change in value will not be stored.
The clear button is used to cancel an entered value. For example, when a new parameter
value has been entered, but the value is not ok, this value has to be cancelled. If the ENTER button
is pushed in combination with the SHIFT button, the old parameter value is restored.
10. Shift button
This button has to be used to access the secondary function of a button. When a button is
pushed without the shift button, it will have its normal function, indicated in white on the button. If
a button is pushed in combination with the shift button the button will have its secondary function,
indicated on the button with the same colour as the shift button. To use the secondary function of a
button, first push the shift button, then push the button itself while holding the shift button. Release
the button and after that release the shift button again.
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 in case of editing the name of a program. In this
case they are used to enter characters (see chapter 6.4.2).
12. Temporary temperature set-point change
When a drying or cool-down cycle is active, the default set-point temperature as adjusted is
set at the moment the drying or cool-down cycle starts. Sometimes it is necessary to manually
adjust the temperature to a higher or lower set-point. This can be done with these buttons in
combination with the SHIFT button (see item 10). If the SHIFT button (see item 10) is pushed in
combination with the INCREASE TEMPERATURE button, the current temperature set-point will
be increased by 5 degrees Fahrenheit (or 2.8 degrees Celsius). If the SHIFT button (see item 10) is
pushed in combination with the DECREASE TEMPERATURE button, the current temperature set-
point will be decreased by 5 degrees Fahrenheit (or 2.8 degrees Celsius). The controller uses
Fahrenheit units internally but the interface units are configurable as either Fahrenheit or Celsius.
When the interface temperature units are set to Fahrenheit increments of 5 degrees increase or
decrease will be displayed. When the interface temperature units are 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 adjusted
value in the active program. This means that in the next program cycle, the settings adjusted in the
program cycle will be used again. Also, if a temporary change is made in the drying cycle of the
program, this doesn’t influence the cool-down temperature setting adjusted.
13. Temporary time change
When a drying or cool-down cycle is active, the adjusted drying or cool-down time is set at
the moment the drying or cool-down cycle starts. Sometimes it is necessary to manually adjust the
time to a higher or lower value. This can be done with these buttons in combination with the SHIFT
button (see item 10). If the SHIFT button (see item 10) is pushed in combination with the
INCREASE CYCLE TIME button, the current time remaining in the drying or cool-down cycle
