Operation
After switching on, the control system starts up the chiller unit
and the connected air handler in steps and then assumes nor-
mal operation. The control element now shows the current tem-
perature where the temperature sensor of the chiller unit is in-
stalled.
Depending on the installation location, this may also be the
temperature of another cabin.
After approx. 20 seconds, the base colour of the control ele-
ment changes to indicate the operating mode (cooling or heat-
ing) in which the chiller unit was started. Blue indicates cooling
mode, red indicates heating mode. The selection depends on:
l
the selected setpoint temperature and
l
the room temperature, which is measured by the cabin
temperature sensor.
The system will go into standby mode when the cabin temper-
ature and the setpoint temperature are the same.
NOTE
The system only cools under the following conditions:
cabin temperature > 15 °C.
Setpoint temperature < cabin temperature.
The system only heats under the following conditions:
cabin temperature < 29 °C.
Setpoint temperature > cabin temperature.
In automatic mode the fan remains set to speed 1 until the cold
water temperature is lower (cooling) or higher (heating) than
the cabin temperature.
In cooling mode, the cold water temperature is significantly be-
low 15 °C and above 40 °C in heating mode. The current cold
water temperature at the outlet of the Ti22 ProX can be reques-
ted in setting level 2 (crew menu).
See Setting level 2.
