Pr
= Proportional part
The speed is changed one increment
per 0.8K deviation from the nominal
value. A high number leads to a more
stable system but also to greater devia-
tion from the temperature set.
Setting range: 0 to 9 = 0 to 0.9K,
ew
=5
In
= Integral part
For 1K of deviation from the nominal
value, the speed is changed one incre-
ment every 4 seconds. A larger number
makes the system stable, but the ad-
justment to the nominal value is slower.
Setting range: 0 to 9 sec,
ew
=5
di
= Differential part
If the nominal value deviates at a speed
of 0.5K per second, the speed is
changed by one increment. Higher val-
ues provide a more stable system but
adjustment to the nominal value is
slower.
Setting range: 0 to 9 = 0 to 0.9K, we=5
u
= Lower speed limit
Example: Lower speed limit = 6
Necessary for avoiding pump standstill
Setting range: 0 to 30,

n
= current speed stage
Current speed stage = 18
n1
= lowest stage
