The existing 24 VAC → 5 V/3.3 V supply was completed and verified earlier. The follow-on executor reports adding:
- ESP32-S3-WROOM-1-N16R8
- Native USB-C programming with BOOT/RESET
- Y1, W1, G, and O/B relay-control channels
- R/Rh, Rc, C, and HVAC output terminals
Remaining work
- Independently verify the new circuitry, GPIO assignments, relay defaults, USB backfeed protection, power budget, firmware document, and ERC results.
- Review any executor-reported caveats.
Execution stopped because no ACUs are currently available; the newly added circuitry should be treated as pending final verification.
Received notification from "ESP32 Thermostat Controller" that it finished — picking the work back up.

The executor completed the ESP32 thermostat controller addition, but I cannot perform the required independent reconciliation because no ACUs are available.
Reported as added
- ESP32-S3-WROOM-1-N16R8 module
- Native USB-C programming
- BOOT and RESET controls
- Four relay channels: Y1, W1, G, and O/B
- HVAC terminals including R/Rh, Rc, and C
Still requires verification
- ERC and complete net connectivity
- USB-C CC resistors and USB power/backfeed behavior
- GPIO selection versus ESP32-S3 boot-strapping pins
- Relay flyback protection and safe power-up defaults
- Contact routing from R/Rh or Rc to each HVAC output
- Updated 3.3 V/5 V power and thermal budgets
Do not manufacture the board until those checks are completed.
Verify controller implementation
Check USB and power
Review HVAC relay safety
