Panasonic Aquarea H67 fault code
Panasonic Aquarea heat pumps
What it means
Abnormal room thermistor, Zone 1
The room thermistor (zone 1) sensor reads open or short circuit.
Safety: Safe isolation before disconnecting sensors or working on the PCB.
UK models this code applies to
From the Panasonic service literature we hold (Panasonic Aquarea installation guide 1.2 (Monobloc H & J generation, ProClub UK) — Error Codes during commissioning) — not a scraped list.
Now the harder half: proving what caused it
H67 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
