Rainwater Module GRM7
The GRM 7 module serves as a fully automated domestic rainwater supply system. As soon as a consumer is switched on, the switch automatically switches on the pump.

If there is no rainwater in the tank, for example after a prolonged dry period, the system is automatically switched over to operation with drinking water.
