Wilo-Stratos PICO, electronically controlled high-efficiency pump

Glandless circulator with screwed connection, blocking-current proof synchronous motor using ECM technology (up to 90 % energy saving compared to an uncontrolled pump) and built-in electronic power control for continuous differential pressure control.

Can be used for all heating and air-conditioning applications (-10 °C to +110 °C).

Control mode can be selected in accordance with the radiator/underfloor heating application.

Control modes:

Permanent, automatic power adjustment to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting)
Settings assistant for number of radiators or underfloor heating area
Variable differential pressure (Δp-v)
Constant differential pressure (Δp-c)
Constant speed (n-const.)

Functions:

Automatic night setback
Fault/warning message display including description and error code in plain text
Venting routine for automatic venting of the rotor chamber
Manual restart function for additional deblocking of the pump as required
Key lock
Function for resetting the electricity meter or for resetting the settings to the factory settings
Dry-running detection
Automatic deblocking function and integrated motor protection
Supports hydronic balancing with the Wilo-Assistant app

Version:

Graphic colour display with operation via one button manual operation level
Slot for Wilo communication modules as an interface for e.g. Bluetooth
Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface (as an accessory)
Minimal consumption only 3 W
Equipped as standard with a thermal insulation shell
5-year warranty

Optional accessories:

Wilo-Smart Connect module BT for Bluetooth connection to mobile devices via Wilo-Assistant app
The Wilo-Connect module BMS expands the interface for use in building management systems (BMS)
Wilo-Connect module Modbus RTU expands the interface for use in building management systems
