The corresponding commands:
In the first line you add the drycooler to the configuration by entering "1". With
"0" you disable the drycooler.
➊
With the parameter "DOUT" you determine a digital output for the drycooler
on/off signal.
➋

Components/Cooling
Drycooler
The start temperature for the drycooler is entered as an absolute value for the
water temperature.
Two different start temperatures for summer
➊a and winter ➊b operation +
hysteresis
➋ can be entered.
The summer/winter operation depends on the setting in the menu Config/
Values GE-mode.
Alarm parameters:

- pre-speed ➎
- control cycle ➏
- P-factor ➐
- max. adjust ➑
are only necessary for the DFC con-
trol, which is explained in the manual GE
systems.
Note:
For the dry cooler control, the configuration of an outside temperature sensor
and a water temperature sensor is required.
