The rainwater unit OPTIMA PLUS combines all the components necessary for operation in one unit. It allows the water to be pumped from the rainwater tank over long transport distances and high delivery heads and fed into the rainwater pipe network under pressure.
Itcontrols the entire rainwater system, monitors the fill level of the storage tank and, if necessary, automatically supplies drinking water to the wall-mounted unit.
Dimensions of the Optima Plus wall-mounted unit (in mm): W 500 x H 510 x D 315

Up to 97% more economical than other rainwater units in standby mode
Thecontrol systems in many rainwater harvesting systems consume up to 15 watts instandby mode , which accounts for the majority of the energy required for rainwater utilization. With theefficient ZETA 02 control unit, developed in cooperation with the Technische Hochschule Mittelhessen, the standby consumption is reduced to less than 0.2 watts. This means energy savings of up to 97% compared to conventional rainwater systems. The ZETA 02 is included as standard in the OPTIMAPLUS rainwater unit.
Uninterrupted water supply
During a prolonged dry period , the system automatically switches to drinking water mode, with the float switch in the cistern acting as a sensor . If necessary, the OPTIMAPLUS can also be switched to drinking water mode manually . In addition, a small intermediate storage tank in the rainwater unit ensures an uninterrupted water supply in the rainwater pipe network at all times.
Pump logic and flow rate
OPTIMAPLUS has two pumps: a powerful submersible pump in the cistern and a centrifugal pump in the rainwater unit. Depending on the operating mode, only one of the two runs at a time. In rainwater mode, the submersible pump in the cistern pumps up to 60 liters per minute to the draw-off points, while the pump in the rainwater unit is inactive to avoid noise pollution in the house. The powerful submersible pump can also be used with longer supply lines between the cistern and the rainwater unit, where distances of more than 25 meters are possible. The submersible pump in the cistern only switches off when it needs to be replenished, and the centrifugal pump in the wall-mounted unit of the rainwater system takes over operation.
