Active cooling
During active cooling all the components in the system are running.
The temperature of the system depends on the radiator/fan
combinations. It is also possible to controll the temperatures in the
system by using a temperature controller that controls the
temperatures between manually set limits.
Passive cooling
During passive cooling the TCT-units are shut down. The rest of the
system is still running this results in a need of less electric power
and lower cooling performance.
0: off (passive)
This means that the TCT-units for active cooling are shut down
while the pumps and fans are still running. This mode can be used
for passive cooling (optional).
I: interior warm (active)
In this mode the system will heat the interior loop up and cool the
exterior loop down.
II: interior cold (active)
In this mode the system will cool the interior loop down and heat
the exterior loop up.
