10.17 Temperature unit Celsius / Fahrenheit (as of software revision 102)
As of software revision 102, the unit for the temperature indication and value selection can be switched between
°C (Celsius) and °F (Fahrenheit). It can be parameterized with step 225:
1.
„Celsius“ (Factory setting)
Temperature indication and value selection in
Celsius (°C).
2.
„Fahrenheit“
Temperature indication and value selection in
Fahrenheit (°F)
Up to and including software revision 101, only Celsius (°C) can be specified on the controller as the temperature
unit.
The degree unit can be changed on the controller without interrupting operation
If you specify temperature indication and value selection in Fahrenheit (°F), the controller still uses
Celsius (°C) internally. Value steps are therefore possible with this function owing to the conversion
from Celsius to Fahrenheit.
10.18 Locking the Configuration menu
It is possible to disable all changes to values/parameters in the Configuration menu. This prevents the controller
configuration from being tampered with by unauthorized persons.
The Configuration menu can be locked or unlocked by pressing the "MENU" key for 2seconds while the power-
up message is displayed (after switching on the controller,
section 10.2.1 "Power-up message" on page 38).
The display then shows a message confirming that the lock function is active for 2seconds before returning to the
home position.
The same message is also displayed for 5seconds when you open the Configuration menu to indicate that this
menu is locked.
You can still display all steps, values and parameters even if the Configuration menu is locked. You
are no longer allowed to enter or change values, however.
The Configuration menu remains locked until the lock function is canceled again. To do so, repeat the above pro-
cedure (press the "MENU" key for 2seconds while the power-up message is displayed). The display then shows
a message confirming that the lock function has been canceled.
In the factory setting the Configuration menu is not locked.
