If the control variable extern is active, the external control param-
eter is displayed on the display.
If the control variable internal is active, the internal control
parameter is displayed on the display.
3. Scroll to another control parameter and select it with the Enter key.

An entry window opens. You can now change the numerical value.
The displayed values Max: and Min: specify the limits for the
value entry.

Control parameter Tv

With Tv manual/auto you can define whether the control parameter Tv
and Td or Tve , Tde and Prop_E are set manually or automatically. If the
automatic setting is enabled, these control parameters are displayed with
a lock and cannot be selected.
To be able to set these control parameters manually, change the control
parameter Tv manual/auto to manual setting.
6.5 Self adaptation
The self adaptation function can be used to automatically find suitable con-
trol parameters for the respective application. Self adaptation can only be
executed on a device with active cooling.
The self adaptation function performs a test run of the constant temperature
equipment to determine the parameters. The device and application must be
ready for operation.
For Integral XT, self adaptation is carried out with the currently set pump
level. The best results can be expected at the highest pump levels. The
pressure control of the pump can be used, but will worsen the result. If
the current consumption of the device is significantly limited, the result
deteriorates and the duration of the self adaptation increases.
The test run must be performed on a passive application. In other words,
changes cannot be made to the application and exothermic or endothermic
reactions may not occur during the test run.
The test run takes between 30 minutes and a maximum of 3 hours,
depending on the application. During the run, the temperature of the heat
transfer liquid deviates a maximum of ±15 Kelvin from the defined setpoint.
After completion of the test run, the newly determined values of the control
parameters are accepted and stored in the [Control parameter] menu. The
old control parameters are overwritten.
