|---|---|---|---|
| Flow Temp Boiler | Water temperature leaving the backup boiler | check_circle | remove |
| COP | Efficiency ratio - heat output divided by electricity input | check_circle | remove |
| Compressor Frequency | Speed of the compressor in Hz, higher values mean more heating or cooling power | check_circle | remove |
| Compressor Frequency | Speed of the compressor in Hz, higher values mean more heating or cooling power | check_circle | remove |
| Defrost Mode | Indicates when the outdoor unit is melting ice buildup | check_circle | remove |
| Delta Temp | Difference between the water leaving and returning to the heat pump, used to show how much heat is being transferred | check_circle | remove |

| Operation Mode | Current mode: heating, cooling, or hot water production. May also show other modes like antifreeze or legionella. | check_circle | tune |
| Operation Mode | Current mode: heating, cooling, or hot water production. May also show other modes like antifreeze or legionella. | check_circle | tune |
| Outdoor Temp | Current outside air temperature measured near the heat pump | check_circle | remove |
| Fan 1 RPM | Speed of the first outdoor unit fan | check_circle | remove |
| Flow Temp | Water temperature leaving the heat pump and going into the heating system | check_circle | remove |
| Target Temp #1 | Target water temperature for the heating circuit in zone #1 | check_circle | remove |
| Liquid Line Temp | Temperature of the liquid refrigerant flowing through the heat pump's cooling circuit | check_circle | remove |
| Power | Whether the heat pump is turned on or off | check_circle | tune |
| Flow Temp | Water temperature leaving the heat pump and going into the heating system | check_circle | remove |
| Water Pump 1 Status | Shows if the water circulation pump is running | check_circle | remove |
| Operation Mode #1 | Operating mode for heating zone #1. In most heat pumps this is either constant flow or compensation curve mode, but some models may support advanced modes like auto-adaptation. | check_circle | tune |
| Operation Mode #2 | Operating mode for heating zone #2. In most heat pumps this is either constant flow or compensation curve mode, but some models may support advanced modes like auto-adaptation. | check_circle | tune |
| Prohibit Heating Hot Water | When enabled, prevents hot water heating | check_circle | tune |
| Eco Hot Water | Energy-saving mode that heats water more slowly using lower flow temperatures for better efficiency | check_circle | tune |
