Operation
After switching on, the control system starts up
the air handler in steps and then assumes nor-
mal operation. The control element now shows
the current temperature where the temperature
sensor of the air handler is installed. Depending
on the installation location, this may also be the
temperature of another cabin for example.
After approx. 20 seconds, the base colour of
the control element changes to indicate the op-
erating mode (cooling or heating) the air han-
dler was started in. Blue indicates cooling
mode, red heating mode. The selection is de-
pendent on the set setpoint temperature and
the room temperature measured by the cabin
temperature sensor.
Note
–
The system only cools under the
following conditions: cabin tem-
perature > 15 °C.Setpoint temper-
ature < cabin temperature.
–
The system only heats under the
following conditions: cabin tem-
perature < 29 °C.
Setpoint temperature > cabin
temperature.
To activate cooling or heating mode, the cen-
tral chiller unit must be switched on and the
cold water circuit must have already been suffi-
ciently heated up or cooled down.
If the cold water temperature is higher (cooling)
or lower (heating) than the cabin temperature,
status message BA11 is displayed and the fan
will not yet be in operation.
In cooling mode, the cold water temperature is
significantly below 15 °C and above 40 °C in
heating mode.
