| Indoor Temp #1 | Current air temperature in rooms served by heating zone #1 | check_circle | remove |
| Thermostat Temp #1 | Desired room temperature set for heating zone #1 | check_circle | tune |
| Return Temp | Water temperature returning to the heat pump from the heating system | check_circle | remove |
| Operation Mode | Current mode: heating, cooling, or hot water production. May also show other modes like antifreeze or legionella. | check_circle | remove |
| Operation Mode | Current mode: heating, cooling, or hot water production. May also show other modes like antifreeze or legionella. | check_circle | remove |
| Outdoor Temp | Current outside air temperature measured near the heat pump | check_circle | remove |
| Flow Temp | Water temperature leaving the heat pump and going into the heating system | check_circle | remove |
| Flow Temp Boiler | Water temperature leaving the backup boiler | 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 |
| 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 |
| Compressor Status | Shows whether the compressor is currently running or idle | check_circle | remove |
