Safety check before first heat test

This is a mandatory pre-check before the first powered heating run. Run the first test with water only and under supervision.

Pre-start checklist

• Setup is stable, dry, and clear of flammable materials.

• Mains power is protected appropriately (for example RCD/FI).

• Enclosure, connectors, and cables are undamaged.

• Sensor assignment is correct and readings are plausible.

• Emergency stop/shutdown path is clear (plug/switch reachable).

• Browser connection is active, but remember: process continues if client disconnects.

First heat test (water)

1. Fill kettle with water (typical partial volume).

2. Set a moderate target (for example 55 to 60 °C).

3. Start heating and monitor temperature rise.

4. Verify target is reached and held stably.

5. Test manual stop behavior.

Abort immediately if

• unusual smell or heating at connectors/cables

• implausible temperature jumps

• unexpected continuous heating or missing shutdown behavior

Next

• Basic setup

• AutoTune step by step

• Troubleshooting
