– Proportional range (P-range) of the internal PI controller
Sets the proportional range of the internal PI controller in %.
Note: This parameter is available only if the internal PI controller is
active.
Factory setting: 10 %
Setting range: 4 - 100 %
Note: The proportional range is used to smoothen the control characteristic.
The larger the selected P-range, the smoother the control
characteristic will be. However, this results in a permanent control
deviation, proportional to the bandwidth of the P-range. For further
information please refer to chapter 9.1.
– Integral time of the internal PI controller
Determines the integral time of the internal PI controller in minutes.
Note: This parameter is available only if the internal PI controller is
active.
Factory setting: 15 minutes
Optional settings: off (no integral time), 2 - 100 minutes
Note: The integral time setting determines the period allowed to
reach the nominal humidity. Setting the integral time to the optimal
value prevents the control characteristic from overshooting and, at
the same time, balances the permanent deviation (caused by the
proportional range setting). For further information please refer to
chapter 9.1.
