> Room temperature hysteresis
The function is only displayed if a the room sensor has
been selected.
> Acknowledge anti-freeze sensor T32
Freeze protection sensor must not be installed together
with the cooling station.
> Flow sensor
Do not change the default value E31.T31
> Dew point sensor installed
Change the value to Yes when the Room transducer for
relative humidity and temperature E11.TM (dew point
sensor) is connected to the cooling station. There is no
automatic acknowledgement, the setting must be
changed to
Yes .
> Safety margin from dew point to T1
The function is only available if a dew point sensor is
installed. This ensures protection against condensation.
> Minimum set point value T1 at cooling
The set point value for T1 is permitted to be lower when
the dew point sensor is connected. Higher flow
temperature is otherwise required to avoid
condensation.
The cooling station mixing valve is controlled by PID
regulation in order to reach the flow set point when
there is a need. The signal determines how much the
opening of the mixing valve should change. It is
calculated with short time intervals. Set default values
give a good function and hardly need any changes.
