 ## Features
- Hot water temperature control
+- DHW temperature control
 - Heating temperature control
 - Smart heating temperature control modes:
   - PID
   - Equithermic curves - adjusts the temperature based on indoor and outdoor temperatures
- Hysteresis setting (for accurate maintenance of room temperature)
- Ability to connect an external sensors to monitor outdoor and indoor temperature ([compatible sensors](https://github.com/Laxilef/OTGateway/wiki/Compatibility#temperature-sensors))
- Emergency mode. If the Wi-Fi connection is lost or the gateway cannot connect to the MQTT server, the mode will turn on. This mode will automatically maintain the set temperature and prevent your home from freezing. In this mode it is also possible to use equithermal curves (weather-compensated control).
- Automatic error reset (not with all boilers)
+- Hysteresis setting _(for accurate maintenance of room temperature)_
+- Ability to connect [additional (external) sensors](https://github.com/Laxilef/OTGateway/wiki/Compatibility#temperature-sensors): Dallas (1-wire), NTC 10k, Bluetooth (BLE). Makes it possible to monitor indoor and outdoor temperatures, temperatures on pipes/heat exchangers/etc.
+- Emergency mode. In any dangerous situation _(loss of connection with Wifi, MQTT, sensors, etc)_ it will not let you and your home freeze.
+- Ability of remote fault reset _(not with all boilers)_
 - Diagnostics:
-  - The process of heating: works/does not work
-  - The process of heating water for hot water: working/not working
-  - Display of boiler errors
-  - Burner status (flame): on/off
-  - Burner modulation level in percent
-  - Pressure in the heating system
-  - Gateway status (depending on errors and connection status)
-  - Boiler connection status via OpenTherm interface
-  - The current temperature of the heat carrier (usually the return heat carrier)
-  - Set heat carrier temperature (depending on the selected mode)
-  - Current hot water temperature
+  - Displaying gateway status
+  - Displaying the connection status to the boiler via OpenTherm
+  - Displaying the fault status and fault code
+  - Displaying the diagnostic status & diagnostic code
+  - Display of the process of heating: works/does not work
+  - Display of burner (flame) status: on/off
+  - Display of burner modulation level in percent
+  - Display of pressure in the heating system
+  - Display of current temperature of the heat carrier
+  - Display of return temperature of the heat carrier
+  - Display of setpoint heat carrier temperature (useful when using PID or Equitherm)
+  - Display of the process of DHW: working/not working
+  - Display of current DHW temperature
+  - _And other information..._
 - [Home Assistant](https://www.home-assistant.io/) integration via MQTT. The ability to create any automation for the boiler!
