HEART sensors.out-of-range H-08002
Reading out of range. A reading is outside what is physically possible.
| Code | HEART sensors.out-of-range; inside a message "code": "sensors.out-of-range" |
|---|---|
| H-number | H-08002: area 08, code 002 |
| Area | sensors: Readings and calibration |
| Typical severity | error. A product may set another for its own case. |
| Applies to | Products with sensors: thermostats, chargers, pumps, printers, trackers, medical devices |
Likely causes
- An open circuit: a thermistor connector open often reads about -38 °C.
- A short circuit, which reads at the top of the scale.
- A wrong sensor type or wrong scale in the settings.
- Damage to a lead or cable, such as a pacemaker lead with impedance outside 200 to 2000 ohms.
How to fix or prevent it
- Check the connector and wiring for opens and shorts.
- Check the sensor type and scale in the settings.
- Replace the sensor or its lead.
What the HEART does by itself
It raises an error alert and treats the value as bad. The product's own firmware often refuses to act on it (a printer refusing to heat). It resolves when readings are back within what is possible.
When to call service
At once for medical leads and safety sensors. Otherwise if the reading stays impossible after checking the wiring.

Inside a message a code is written bare, "code": "storage.full". In logs, tickets, documents and searches it is written
HEART storage.full. Things that simply happen, such as system.started, are event types, not faults.
The codes are defined in Part 3, Section 5.4, and their H-numbers in Section 5.7.
