Parameter
Volume flow V [m
Volume flow calculation according to: V = k · √Δp
with: V = Volume flow in [m
Volume flow range up to 999,999 m
K-factor:
Maximum volume flow (V
Measuring range:
Measuring range: 500 Pa, k=10,000
Measuring range: 1000 Pa, k=10,000
Measuring range: 2000 Pa, k=10,000
Measuring range: 4000 Pa, k=10,000
Measuring range: 6000 Pa, k=10,000
Differential pressure from 0 % up to 100 % of measuring range.
Limit values:
Volume flow from 0.5 % up to 100 % of measuring range, k-factor is
considered.
Nominal
Differential pressure from 0 % up to 100 % of measuring range.
values
Volume flow from 0.5 % up to 100 % of measuring range, k-factor is
(setpoints):
considered.

positive/(heating): Control deviation = set value – actual value
Control
The output increases when: Set value > actual value
characteri-
negative/(cooling): Control deviation = actual value – set value
stic:
The output increases when: Actual value > set value
