| Available | Offers the mode in the web interface, smart-home app and paired Serin Link. Auto requires Heat and Cool. After changing availability, select Reboot Now so the app shows the change. |
| Heat Pump Limits | Uses the target temperature range reported by the indoor unit. |
| Custom Limits | Sets Low and High with −/+. The indoor unit may refuse targets outside its reported range. |
Dry shares Cool's range; Fan has no range. The summary below the list shows the app and Serin Link range, spanning all enabled mode ranges. See Set modes and temperature ranges for the procedure.

ESPHome settings
ESPHome uses the entities and controls enabled in its YAML. It does not use the HomeKit/Matter Device settings page. See standard entities and configuration options.
Settings the controller does not have
HomeKit-compatible and Matter-compatible firmware have these limits:
- Static IP address. The controller gets its address from your router. To keep the address the same, reserve it for the controller in your router's settings.
- Status light brightness. The light cannot be dimmed or turned off.
- Time zone. The controller sets its clock from the internet, and the web interface shows times in your phone or computer's time zone.
- Password for the web interface. Anyone on your local network can open it. See security.
- Automatic updates. The controller never installs an update by itself. See Update firmware.
