Some units have a fault indicator on the supply air side which
illuminates red when there is a fault message or maintenance
message. As a result you are able to detect faults occurring in
units that are operated without a programming unit.
If you cannot remedy the fault, contact your qualified contrac-
tor. Give the number on the type plate to the qualified contractor
(000000-0000-000000). The type plate is located on the control
panel on the side of the appliance.
