Select actual value (parameter
ID 333
to
ID 339
) and the PID control reference (parameter
ID 332
). If value 6 is selected for this param-
eter in PID Control Application, the values of parameters
ID 319
and
ID 301
are automatically set to 13.
In Pump and Fan Control Application, the functions Motor potentiometer DOWN and Motorpotentiometer UP must be connected
to digital inputs (parameters
ID 417
and
ID 418
), if value 6 is selected for this parameter.

Location in the menu:
P2.2.35
(PID Control Application)
P2.2.1.18
(Pump and Fan Control Application)
Use this parameter to set the minimum scaling point of the reference value.
10.103 (ID 345) Reference Scaling Maximum Value
Location in the menu:
P2.2.36
(PID Control Application)
P2.2.1.19
(Pump and Fan Control Application)
Use this parameter to set the maximum scaling point of the reference value.
