Zeta 02
Pump Controller

WISY AG develops energy-efficient pump controller

WISY AG based in Kefenrod Germany has developed a new pump controller for controlling pumps, pressure booster systems, domestic pressure boosting and rainwater units. This innovative product consumes much less power in standby mode than conventional pump controllers. Its high energy-saving potential also helps to reduce CO₂ emissions.

Huge energy-saving potential

Thanks to its innovative electronic circuitry, the controller consumes only 0.2 watts in standby mode, a significant reduction when compared to other commercially available controllers which draw between 6 and 15 watts from the grid. This saves up to 128 kWh per year and reduces CO₂ emissions by up to 97% or 70 kg per year.

Ecodesign compliant

With this new product, WISY has opted to satisfy the strict new requirements of the Ecodesign Directive drawn up by the European Union which states that the standby power usage of many products used in domestic or office environments must not exceed 0.5 watts. While the exacting standards laid down in this directive do not yet apply to pump controllers, WISY has developed a product which is already compliant!

Only WISY Rainwater units are equiped with the new ZETA 02 pump controller.

Great for the environment and great for the user:

Lower CO₂ emissions and lower energy bills! The high power usage of conventional pump controllers in standby mode is best illustrated by comparing them to other electrical devices: For example, a modern standard pump controller consumes even more power per year than a large flat-screen television. The financial advantage to users of the new WISY pump controller is obvious - a reduction in power consumption means much cheaper energy bills.

Security through prgrammable functions

1. Adjustable run-on time

The pump run-on time after closure of all extraction points can be set to between one, three, five and ten seconds. This helps to reduce power consumption and cut energy costs.

2. Overfrequent starting detection

Overfrequent starting reduces the service life of the pump. You can therefore program the ZETA 02 pump controller to detect overfrequent starting and shut down the pump if it starts up more than 25 times per hour. A continually flushing toilet or a dripping garden watering tap will cause the pump to shut down so as to prevent damage to the pump and water wastage.

3. Detection of continuous pump operation

A great deal of water can be lost if a pipe ruptures or a garden hose bursts. For this reason, you can program the pump controller to detect continuous pump operation lasting more than ten minutes and shut down the pump.
