Third control level (A parameters):
Setting of control parameters
To access the third control level, enter the second level first and scroll through the parameter list
until you reach the highest parameter. Then, click the UP button for at least 10 seconds. The
message "PA" will be displayed.
Then, press UP and DOWN buttons simultaneously for at least 4 seconds to access the parameter
list of the third control level (starting with A1).

Description of parameters:
The following values affect the properties of the appliance and
any changes should be considered carefully for this reason:
A1: Control characteristic in turbo program "Pr.4"
Here, you can define the control characteristic to be used while program "Pr.4" is active. You can
choose between thermostat behavior and PID characteristic based on parameter group "P20-P23".
The control philosophy of the controller is such that "Pr.4" has the highest heating power.
A2: Activation of fat warning message
Here, you can define if control is to be blocked when the hot fat time set in parameter "P26" has
elapsed.
A3: Activation of control blocking
Here, you can define if control is to be blocked when the hot fat time set in parameter "P27" has
elapsed.
Important note:
Any modifications by the customer at this control level is not permissible and can result in
dangerous functional changes.
