Parameter
Volume flow V [m
Chracteristic
curve linear or square root
Volume flow calculation according to: V = k · √Δp
with: V = Volume flow in [m
K-factor:
volume flow display indication up to 999,999 [m
measuring mode and control mode
differential pressure from 0 % p to 100 % of measuring range
Setpoint
volume flow from 0,5 % up to 100 % of measuiring range,
k-factor is considered

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