Setpoint
differential pressure from 0 % p to 100 % of measuring range
Set = 8888
volume flow from 0,5 % up to 100 % of measuiring range,
k-factor is considered

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
