Operating Guide
The control parameters are used for different issues, for example
temperature and pump speed control.
Parameters Xp (proportional band) with ID 1x184 are also used
for pump speed control.
Parameters Tn (integration time constant) with ID 1x185 are also
used for pump speed control.
Parameters Nz (neutral zone) with ID 1x187 are also used for pump
speed control.
Parameters V out max. and V out min. (ID 1x165 and 1x167) are
setting the limits for the control voltage as well as for the PWM
control.
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.

When the pump is controlled at low speed (in pulsed mode) the regulation
can be dampened. A too low dampening can result in unstable temperature
regulation.
