Braemar Ducted Systems – Status & Fault Code Index (SDHV / KDHV) - Residential Service Guide ES E247-A 

Applies to

Braemar ducted reverse cycle inverter systems covered in the
Braemar Residential Service Guide ES E247‑A, including:

  • SDHV / SCHV Series – R410A ducted (single & three phase)
  • KDHV / KCHV Series – R32 ducted inverter systems

Important note

Ducted systems use a dedicated fault and protection code structure that differs from wall split, cassette, bulkhead, and multi‑split units.

When diagnosing SDHV or KDHV systems, always refer to the ducted-specific error code table in the service manual.


Where to find ducted fault codes

  • “Error codes for ducted split systems” – ES E247‑A, PDF page 62 onwards


Common ducted system fault codes

Compressor & system protection

CodeDescription
E1Compressor high pressure protection
E2Indoor anti‑freezing protection
E3Compressor low pressure / refrigerant protection
E4Compressor discharge high temperature protection
H3Compressor overload protection
H5IPM (inverter module) protection

Electrical & communication faults

CodeDescription
E6Communication error (indoor ↔ outdoor)
PLDC bus low voltage protection
PHDC bus high voltage protection
PUCapacitor charging / inverter fault

Fan & airflow related faults

CodeDescription
E8Indoor fan fault
H6DC fan motor fault
F6Frequency reduction due to overload

Sensor & control faults

CodeDescription
F0 – F5Thermistor and control sensor circuit faults
C4 / C5Jumper plug fault
EE / eeMemory or EEPROM fault

Common troubleshooting guidance

  1. Confirm the unit is SDHV or KDHV
  2. Reference ducted error code table only (PDF p62+)
  3. Address protection faults before electrical faults
  4. Verify communication wiring for E6 faults
  5. Review commissioning status if recently installed

Avoid common misdiagnosis

  • Do not reference wall split or cassette fault charts
  • Do not apply non‑ducted fault logic to ducted systems
  • Always identify system type before fault diagnosis
