About setting 19(29)-0-04 and 19(29)-0-05
If the user interface is switched off while you are activating setting 19(29)-0-04 or 19(29)-0-05, the configuration is aborted. When you switch the user interface back on, the function starts
from the beginning. Setting 19(29)-0-04 takes between 1 and 6 minutes to complete. You can check if the setting was completed successfully by checking if the field setting is changed to
0-01. Setting 19(29)-0-05 takes between 3 and 35 minutes to complete. You can check if the setting was completed successfully by checking if the field setting is changed to 0-02. You can
ONLY activate these settings with clean filters. Make sure that the ducting pressure drop of the top and bottom units is balanced. The function starts as soon as it is selected and the user
interface is on. Setting 19(29)-0-04 CANNOT be configured if the outside temperature is ≤-10°C, which is out of the operation range. Setting 19(29)-0-05 CANNOT be configured if the
outside temperature is ≤5°C. In this case error 65-03 is shown and the unit stops working. Change the setting to 19(29)-0-04. The setting CANNOT be configured if there are alerts or errors
present. If booster fans are used, you can ONLY configure setting 19(29)-0-03. You can configure settings 19(29)-0-04 and 19(29)-0-05 for multiple units with 1 user interface.
