+ * @brief Controls the filtration mode of the Neopool device connected via modbus
+ * 
+ * Possible states:
+ *  - automatic
+ *  - off
+ *  - slow
+ *  - medium
+ *  - fast
+ * 
+ * To read the state:
+ *  reads relay register 0x010E, with bitmasks 
+ *    - 0x0100 slow
+ *    - 0x0200 medium
+ *    - 0x0400 high
+ *    - 0x0010 filtering
+ *  auto / non-auto:  0x0411: 
+ *    -   MBV_PAR_FILT_MANUAL = 0, // This mode allows to turn the filtration (and all other systems that depend on it) on and off manually.
+ *        MBV_PAR_FILT_AUTO = 1,   // This mode allows filtering to be turned on and off according to the settings of the TIMER1, TIMER2 and TIMER3 timers.
+ * 
+ * To set the manual state:
+ *    set filtration speed to addr 0x050F (MBF_PAR_FILTRATION_CONF), register needs to be read first to be correctly modified
+ *    set MBF_EXEC to 1
+ *    set filtration mode to manual (=0) via MBF_PAR_FILT_MODE (0x0411) 
+ *    set manual mode filtration to on 0x0413 to  0, 1, 2, ?
