Bosch Climate 5000 EC 07 outdoor fan speed fault

What Does Error EC 07 Mean?

On Bosch Climate 5000 Generation 3 R-454B multi-zone equipment, EC 07 means the outdoor fan speed is outside the control's expected range. The service procedure considers fan obstruction and assembly, motor wiring and feedback, the motor itself, and the outdoor PCB; the code does not select one of them. Applies to: Climate 5000 Generation 3 R-454B multi-zone This code definition applies only to the May 2025 Climate 5000 Gen 3 R-454B multi-zone manual. Earlier R-410A Climate 5000, single-zone, IDS, boiler, and Compress products use different references. Owner-safe checks: With the unit off, document EC 07, the exact outdoor model, guard and clearance condition, ice, and fan behavior from outside the cabinet. Qualified technician: Fan access, motor resistance and feedback, harness, live inverter-board, refrigerant, and R-454B safety checks require qualified Bosch service.
