5.3 Adjustable parameters
Parameter Selection or parameter range Default set-
ting
Unit Metric or imperial metric
Operating
mode: Measuring mode or control mode measuring mode
Parameter Differential pressure ΔP [Pa] or [InH2O]
Volume flow V [m3/h] or [cfm]
differential
pressure ΔP [Pa]
K-factor:
Volume flow calculation according to: V = k · √Δp
with: V = Volume flow in [m3/h]or [cfm]
k = flow factor, adjustment range: 1...10,000
Δp = differential pressure in [Pa]or [InH20]
Volume flow range up to 999,999 m3/h
Maximum volume flow (Vmax)
Measuring range: 50 Pa, k=10,000 Vmax = 70,710 m3/h;
Measuring range: 500 Pa, k=10,000 Vmax = 223,607 m3/h;
Measuring range: 1000 Pa, k=10,000 Vmax = 316,228 m3/h;
Measuring range: 2000 Pa, k=10,000 Vmax = 447,214 m3/h;
Measuring range: 4000 Pa, k=10,000 Vmax = 632,456 m3/h;
Measuring range: 6000 Pa, k=10,000 Vmax = 774,597 m3/h
K = 70

Output vol-
tage: 0 … 10 V DC Uout = 10 V DC
P-gain: 0 ... 1000 P = 50
I-gain: 0 … 100 I = 3.15
Control
characteristic:
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
