Display Fault description/note
Heat-
pump fault
(E 54)
Heat pump fault The flow monitor has tripped. A flow problem has occurred. Possible causes
are air in the system, a clogged dirt trap or a defect of the charging pump in the indoor
module. If the red indicator lamp illuminates, there is a problem in the outdoor module which
can only be remedied through customer service.
E 69 Failure or short in supply sensor HK2 (mixing circuit). Sensor F5
E 70 Failure or short inlet pipe WP Multi-purpose sensor 1 Sensor F11
E 71 Failure or short in lower buffer sensor Sensor F12
E 72 Failure or short in upper buffer sensor No assignment by REMKO
E 75 Failure or short, external sensor Sensor F9
E 76 Failure or short, domestic water sensor Sensor F6
E 78 Failure or short, collector sensor Sensor F8
E 80 Failure or short, room sensor heating circuit 1. No assignment by REMKO
E 81
EEPROM error. The valid value has been replaced by the default value. Check parameter
values!
E 83 Failure or short, room sensor heating circuit 2. No assignment by REMKO
E 84 Fault humidity, sensor No assignment by REMKO
E 90 Address 0 and 1 on bus. Bus codes 0 and 1 may not be used simultaneously.
