D
component
D component of the PID controller.
The derivative time TV of the PID controller is specified in this setting.
The derivative time is only effective with fast changes in the actual value.
Increasing the derivative time causes a more dynamic transient response.
TV=0 switches off the D component.
Setting limits: 0… 999s
Factory setting: 16s
The procedure for changing one of the PID parameters is as follows:
First select the zones on the left whose parameters are to be changed
Then, on the right side, select the desired parameter
Open the box for entering the value with
Enter the desired value in the input box
Confirm with OK.
5.3.2.4.2 Heating signal
Clicking on the
selection button opens the heating signal selection. A distinction is drawn in principle between pulse
operation and phase control for the heating signal. Pulse operation and phase control are two different means of
controlling the heaters.
Setting
Description
Pulse operation During pulse operation, the heating output is switched on and off at full voltage in a
specific ratio. The ratio of the time switched on to the time switched off is determined
by the output level that is calculated by the controller. An output level of 25%, for
example, means that the output is switched on for one time unit and then remains
switched off for 3 time units.
With a high output level, pulsed operation delivers better control behaviour. The
output switches the voltage in zero crossing mode, which causes less wear on the
heating unit among other things.
Factory setting: all zones in pulse operation
Phase control
With phase control, the voltage at the heating output is kept proportional to the
calculated output level. With a lower output level, phase control ensures better
control behaviour. Phase control, however, causes more wear than pulse operation.
Factory setting: All zones in pulse operation
Mixed
This setting activates a combination of both operating modes, uniting the
advantages of both.
Factory setting: All zones in pulse operation
The procedure for changing the heating signal is as follows:
First select the zones on the left whose heating signal is to be changed.
