The OPTIMA PLUS rainwater unit combines all the components required for operation in one device. It enables the water to be pumped from the rainwater storage tank over long delivery distances and high delivery heads and feeds it into the rainwater pipe network under pressure.
Itcontrols the entire rainwater system, monitors the filling level of the storage tank and, if necessary, automatically feeds drinking water into the wall-mounted unit.

Up to 97 % more economical in standby than other rainwater units
The controls of many rainwater units have a power consumption of up to 15 watts in standby mode , which accounts for most of the energy required for rainwater utilisation. With the efficient ZETA 02 pump controller, developed in cooperation with the Technical University of Central Hesse, the standby consumption is reduced to less than 0.2 wat ts. This means energy savings of up to 97 % compared to conventional rainwater units. The ZETA 02 is included as standard in the OPTIMA PLUS rainwater units.
