+Poupool currently controls **filtration** (including backwash), **heating** (heat pump), **pH and
+chlorination**, **cover**, **lights** and all the pumps and valves of the system. It is used for an overflow
 swimming pool so that adds some complexity to the control process (e.g. monitoring of the retention
 tank water level).
 
 The main interaction with the system is done through modes. Here are some of the main ones:
 
-* **eco** : cover close, filtration, pH, chlorination and heating are automatic
-* **standby** : cover open, no overflow
-* **overflow** : cover open, overflow, chlorination is forced
-* **comfort** :  cover open, no overflow, heating is forced
