1.1 Modes of operation
Automatic mode
In Automatic mode, the pump carries rainwater from the tank into the home and onto respective
applications (e.g. toilets etc.). If the tank is empty, this is detected by the float switch in the tank, which
instructs the electronic 3/2-way ball valve to change to the mains water mode. The rainwater intake line is
then blocked and the required mains water is sourced from the built-in supplemental supply container
inside the
RM Favorit
. After it rains, and the tank is topped-up with rainwater again, the float switch
detects this and the electronic 3/2-way ball valve switches back to the rainwater intake setting.
Maintenance mode
In Maintenance mode, the electronic ball valve stays permanently switched to mains water mode, and the
house is continuously supplied with mains water from the supplemental supply container inside the
RM Favorit
.
In both working modes, the pump is switched on and off by means of the built-in pressure switch. The
anti-dry running protection of the pump, and the stagnation protection of the supplemental water supply
(the regular refreshing of water in the supplemental supply) are automatically controlled by the unit‘s
built-in pump-controller.
