E Control parameters
The control parameters have been optimized at the factory for operation as a bath thermostat (with water as the heat
transfer liquid) with internal control. The standard parameters are already set as default also for the thermostatic
control of external applications with external control.
Depending on the application, the configuration can be adapted from case to case as required. Also the thermal
capacity and the viscosity of the heat transfer liquid affect the control behavior.
Note: Only change the control parameters if you have adequate knowledge of control techniques.
If you have not connected any temperature sensor, read further here. For activated external control read (

11.14).
The control corresponds to the set-point temperature with the current bath temperature and calculates the set value for
heating or cooling.
These control parameters can be set:
Description Short form Unit
Proportional range Xp K
Reset time Tn s
Derivative time Tv s
Damping Td s
If " Tv manual/auto " is set to "a" (automatic), Tv and Td cannot be changed. They are in this case derived from Tn with
fixed factors.
Consider the effect of the temperature limits Tih and Til (

7.4.5) on the control.
