Wilo-Yonos PICO-Z

Quick switch to energy-saving domestic hot water circulation.

The compact Wilo-Yonos PICO-Z is the ideal replacement pump when switching to energy-saving circulators for domestic hot water applications in detached, semi-detached and multi-family houses. The high-efficiency pump equipped with a thermal insulation shell offers a high-degree of hygienic safety due to its stainless-steel housing. The Wilo-Connector enables quick electrical installation. Replacing a Wilo-Star-Z is very easy due to new, equivalent pump versions as well as the continuous control mode “n-cst” for selecting the correct pump curve. With the automatic and manual restart as well as the pump venting function, the Wilo-Yonos PICO-Z offers all the standard functions required for reliable operation.
