outflow temperature and calculates the actuating signal, i.e. the
amount to be heated or cooled.
Tab. 7: The following control parameters can be adjusted for
internal control:
Parameter Description Unit
Xp Proportional range K
Tn Reset time s
Tv Lead time s
Td Damping time s
If Tv manual/auto is set to Auto , Tv and Td cannot be
changed. In this case, they are derived with fixed factors
from Tn.
