7.13 Power Supply
Operating Instructions
Version 1.5
After closing the condensate trap, it must be locked again with the same but-
ton. The fans do not start back up again until the condensate trap has been
locked.
If the „Condensate Trap Error“ alarm cannot be reset with the „Reset Alarm“
button, the system must first be switched to the service mode and the „Open
Condensate Trap“ button must be clicked. As a result, the condensate trap
fans are no longer activated.
If the „Open Condensate Trap“ button indicates that the fans are at a stand-
still („Stopped“), the lock can once again be secured with the help of the
„Open Condensate Trap“ button, and the fans can be operated again. „Run-
ning“ should then appear at the display and the alarm should be reset.
