11.5.4 Operating principle
It is possible to enter absolute and relative limitation. If only one of the these
functions is desired, the other function can be deactivated by setting the setpoints
far outside.
If there is no supply air temperature sensor, limitation is set inactive.
Supply air limitation, absolute
If the Limit value high or Limit value low is exceeded, the limiter function overrides
the normal control function with PI control to adhere to the limitation setpoint.
