The motorised ball valve will move into the “rainwater“ intake position unless water is present in the separation tank. Let the water run from the air valve into the water bucket until there is no more sign of bubbles (a clear stream), meaning that all the air has been removed from the suction ...
7.3 Modes of operation and display The green LED on the pump controller indicates that the pump is ready to use. In case of a problem, the red LED will light up (see chapter 5.1) The system pressure can be read on the pressure LED indication of the pump controller. The Automatic Mode or Maintenance Mode can be set via the mode selecting switch. 7.3.1 Automatic mode (Switching position I ) Automatic mode is the normal operating mode, and is selected by Switch position I. In this mode, the unit automatically switches from rainwater to mains water if the float switch detects that the rainwater tank is empty. ...
7.3.2 Maintenance mode (Switch position II ) The maintenance mode is selected by Switch position II. This mode is selected only when maintenance is to be performed in the tank. The RM Favorit‐SC then operates in continuous mains water mode, independent of the float switch. 8.

Dry running If no water is supplied, the LED blinks and the pump stops after 40 seconds. After 5 unsuccessful A8 Working automatic restarts, the pump permanently stops and the LED turns solid. All alarms are shown with the corresponding LED on the circular LED display. The alarm indicator blinks if the alarm has an automatic restart function (e.g. Dry running). The alarm does not blink, if a manual restart is necessary for safety (press STOP, the START). Protections and alarm details: CURRENT PICK PROTECTION (A1): The inverter immediately stops the current in case this value exceeds a maximum limit for the electronic components. CLOSED DELIVERY WORKING PROTECTION (A7): To prevent pump operation with closed delivery, the control logic monitors the motor’s operating point condition in comparison to the pump operating curve. If the operating point is below the pump curve, the controller switches off the pump and displays “Minimum Flow”. (The pump operating curve is detected by the self‐initialization check.)
