Wilo-Yonos PICO-ZD

Quick switch to energy-saving hot water circulation for residential and commercial buildings.

The Wilo-Yonos PICO-ZD is the ideal replacement pump when switching to energy-saving circulators for domestic hot water applications in residential and commercial buildings. The high-efficiency twin-head pump enables the use of all control modes in both single and parallel operation. Its stainless steel housing and the internal bypass circulation prevent Legionella growth. The Wilo-Connector enables quick electrical installation. New, equivalent pump variants with the continuous control mode “n-cst” for correct pump curve selection make replacing a Wilo-Star-ZD very easy. With the automatic and manual restart and the pump venting function, the Wilo-Yonos PICO-ZD offers all the standard functions required for reliable operation.


Your advantages

  • Hygienic safety ensured by stainless steel pump housing and internal bypass circulation
  • EC motor enables energy-saving supply
  • Easy maintenance and a higher degree of operational reliability with automatically and manually triggered restart or pump venting function for each pump
  • Current parameters such as flow and power consumption in view at all times via LED display
  • Green Button Technology, intuitive user interface with LED display and continuous control functions offer ease of use
  • Simple electrical installation with the Wilo-Connector
Series description

Design

Glandless twin-head circulator with screwed connection, blocking-current proof EC motor and integrated electronic power control.

Application

Domestic hot water circulation systems in building services and industry.

Equipment/function

Operating modes

  • Δp-c for constant differential pressure
  • Constant speed (3 constant speed stages)
  • Constant speed (continuously adjustable)

Manual functions

  • Setting the operating mode
  • Setting of pump output (delivery head)
  • Setting the constant speed (continuous or fixed)
  • Pump venting function
  • Manual restart

Automatic functions

  • Continuous power adjustment depending on the operating mode
  • Automatic restart
  • Automatic dry-running detection

Signal and display functions

  • Display of the current power consumption in W
  • Display of the current volume flow in m³/h
  • Displays during setting:
    • Delivery head in m
    • Constant speed (c1, c2; c3)
    • Speed during continuous adjustment (n/100)
  • Display of fault messages (error codes)
  • Display of manually activated restart or pump venting function

Equipment

  • Quick electrical connection with Wilo-Connector
  • Blocking-current proof motor
  • Particle filter

Twin-head pump function

  • Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling). If the twin-head pump is to be operated in main/standby operation, the control mode and the delivery head or speed stage must be set so they are identical.
  • Parallel operation (efficiency-optimised peak load activation and deactivation). If the twin-head pump is to be operated in parallel/peak-load operation, the control mode and the delivery head or speed stage must be set so they are identical.
  • An additional switchgear is required for switching the pumps, e.g. in the event of a fault.
