Limit values:
Differential pressure from 0 % up to 100 % of measuring range.
Volume flow from 0.5 % up to 100 % of measuring range, k-factor is
considered.

Control
characteri-
stic:
positive/(heating):
Control deviation = set value – actual value
The output increases when: Set value > actual value
negative/(cooling):
Control deviation = actual value – set value
The output increases when: Actual value > set value
positive / heating
If selected parameter = volume flow
than follows the additional input for the k-factor
