Limits
Limits can be defined for the temperature and speed of the air handling
system via the following parameters.
* in systems without room set value transducer
** in systems with room set value transducer
*** for systems with stepped or stepless electric heater bank

Heat generation
Preheat program
The preheat program can be activated via a parameter.
Activating the preheat program prevents cold air being blown into the room
at system start (when heating coil (bank) is cool).
Prior to the fan starting, the system checks whether the outside temperature
lies below an adjustable limit. If that is the case, the heating circuit pump
starts for a programmed time, and the valve opens.
The preheat program cannot be activated on systems with an electric
heating coil.
KGWO
The parameters ensure that when the KGWO is active, there is always
a minimum air flow across the heat exchanger. When the contact of the
thermostat for fan run-on closes, the air damper is opened to the set
minimum damper position.
