Uninterrupted water supply
During a prolonged dry period, the system automatically switches to drinking water mode using the float switch in the cistern as a sensor. If necessary, the OPTIMA 4 and OPTIMA 5 can also be switched to drinking water mode manually. In addition, a small buffer tank in the rainwater unit ensures an uninterrupted water supply to the rainwater pipe network at all times.
