4.5.6 Heating/Cooling system
The actuator can be adapted to the given heating/cooling system by control parameters. The settings
are the same for heating and cooling:

Table 50: Heating/cooling system
The control parameter, proportional range and reset time, are adjusted by the setting for the
heating/cooling system.
It is possible to use predefined values, which fit to certain heating/cooling systems, or to
parameterize the proportional range and the reset time individually. The prederined values for the
belonging heating or cooling system are based on practical tested values and lead mostly to good
control results.
If a free Adjustment is chosen, proportional range and reset time can be chosen freely. This setting
needs enough knowledge at the area of control engineering.
