Compact Ventilation Units AIR1 XC
Stop conditions:
– The outside temperature is higher than the set start value (e.g. 18 °C) or lower than the set minimum value (e.g. 10
°C).
– The room temperature is lower than the set stop value (e.g. 18 °C).
– A ventilation stage other than those listed above is active.
– It is not the set time of day.
The start and stop conditions must be set in the commissioning assistant.
Free cooling / Free heating
This function opens the bypass under the conditions described below. This uses the intake air temperature for heating
or cooling.
1. If the unit has heating requirements:
Case 1 – If the supply air temperature < intake air temperature and the extract air temperature < intake air temperature,
then the bypass shutter is opened.
Case 2 – If the supply air temperature < intake air temperature and the extract air temperature > intake air temperature,
then the bypass shutter is closed.
2. If the unit has cooling requirements:
Case 3 – If the supply air temperature > intake air temperature and the extract air temperature > intake air temperature,
then the bypass shutter is opened.
Case 4 – If the supply air temperature > intake air temperature and the extract air temperature < intake air temperature,
then the bypass shutter is closed.
Prevention of pressure losses
If the supply air, extract air, intake air and exhaust air temperatures are equal, heat recovery is not required. The unit
opens the bypass shutter to prevent unnecessary pressure loss.
If the supply air temperature = intake air temperature = extract air temperature = exhaust air temperature, then the
bypass shutter is opened.
4�1�6 Overrun
The unit has an adjustable overrun function for ventilation stage selection via an external switch contact.
Thus, the ventilation unit will run for the set time after actuation of the switch contact for the respective ventilation stage.
Therefore, a push-button function is possible.
If the overrun time is set to 0,the ventilation unit will run until the corresponding switch contact is no longer actuated.
Adjustment of overrun time:
• Log on as User or Administrator
• Call up the "Timer" menu
• Call up the "Overrun" menu
• Set the desired overrun time
