# Choosing Basic Attributes

Select the "Main Attributes" menu.

| Attribute | Description | Attribute Name |
| ---------- | ----------- | -------------- |
| **Name** | Name of the entity (this will be the name of the integration and the `climate` entity). | |
| **Temperature Sensor** | Entity ID of the sensor providing the room temperature where the device is installed. | |
| **Last Updated Sensor (optional)** | Prevents safety shutdowns when temperature is stable and sensor stops reporting. (see [troubleshooting](troubleshooting.md#why-does-my-versatile-thermostat-go-into-safety-mode)) | |
| **Cycle Duration** | Duration in minutes between each calculation. For `over_switch`: modulates on/off time. For `over_valve`: calculates valve opening. For `over_climate`: performs controls and recalculates self-regulation coefficients. With the `over_switch` and `over_valve` types, calculations are performed at each cycle. In case of changing conditions, you will need to wait for the next cycle to see a change. For this reason, the cycle should not be too long. 5 minutes is a good value, but it should be adjusted to your heating type. The greater the inertia, the longer the cycle should be. See [Tuning examples](tuning-examples.md). If the cycle is too short, the radiator may never reach the target temperature. For example, with a storage heater, it will be unnecessarily activated. | `cycle_min` |
| **Equipment Power** | Activates power/energy sensors. Specify total if multiple devices (same unit as other VTherms and sensors). (see: Power shedding feature) | `device_power` |
| **Centralized Additional Parameters** | Uses outdoor temperature, min/max/step temperature from centralized config. | |
| **Centralized Control** | Enables centralized thermostat control. See [centralized control](#centralized-control) | `is_controlled_by_central_mode` |
| **Central Boiler Trigger** | Checkbox to use this VTherm as a central boiler trigger. | `is_used_by_central_boiler` |

| Feature | Description | Attribute Name |
| -------- | ----------- | -------------- |
| **With opening detection** | Stops heating when doors/windows open. (see [managing openings](feature-window.md)) | `is_window_configured` |
| **With motion detection** | Adjusts target temperature on room motion detection. (see [motion detection](feature-motion.md)) | `is_motion_configured` |
| **With power management** | Stops device if home power consumption exceeds threshold. (see [load-shedding management](feature-power.md)) | `is_power_configured` |
| **With presence detection** | Changes target temperature based on presence/absence. Differs from motion detection (home vs room level). (see [presence management](feature-presence.md)) | `is_presence_configured` |
| **With automatic start/stop** | For `over_climate` only: stops/restarts device based on temperature curve prediction. (see [automatic start/stop management](feature-auto-start-stop.md)) | `is_window_auto_configured` |

> ![Tip](images/tips.png) _*Notes*_
> 1. The list of available functions adapts to your VTherm type.
> 2. When you enable a function, a new menu entry is added to configure it.
> 3. You cannot validate the creation of a VTherm if all parameters for all enabled functions have not been configured.
