Introduction
WISY AG, based in Kefenrod, Germany, has developed an innovative pump controller, the ZETA 02, designed to significantly reduce energy consumption and CO2 emissions. This product is suitable for use with all standard pumps and can be retrofitted to existing SA06 pump controllers.

Specifications
- Voltage: 110 - 240 V
- Frequency: 50/60 Hz; single-phase
- Standby Power Consumption: 0.2 W
- Cut-in Pressure: 1.5 bar
- Maximum Pressure: 10 bar
- Flow Rate: 160 l/min
- Connections: 1” outside thread

Energy and Cost Efficiency
The WISY ZETA 02 pump controller reduces energy consumption by up to 132 kWh per year and CO2 emissions by up to 97%, equating to a reduction of 70 kg of CO2 per year. This efficiency translates into significant cost savings over 20 years, especially with potential annual price increases of 0%, 3%, or 8%.

Environmental Impact
By reducing standby power consumption to just 0.2 watts, the ZETA 02 complies with the EU's Ecodesign Directive, which mandates low standby power usage. This is a significant improvement over conventional controllers that consume between 6 and 15 watts in standby mode.

Collaboration and Development
WISY AG developed this product in partnership with the Centre for Research and Transfer at the Mittelhessen University of Applied Sciences. The controller's innovative electronic circuitry is a key factor in its energy efficiency.

Conclusion
The WISY ZETA 02 pump controller offers an environmentally friendly solution that reduces energy bills and CO2 emissions, making it a beneficial choice for both users and the environment.
