This circulator is suitable only for drinking water.
Maintenance-free domestic hot water circulator (glandless pump version) with screwed connection, blocking-current proof synchronous motor according to ECM technology and built-in electronic power control for continuous differential pressure control. With the highest efficiency levels and high starting torque, including automatic deblocking function. Suitable for all domestic hot water systems (+2 to +95 °C).
Control modes:
– T-const. for temperature-controlled mode
– Δp-c for constant differential pressure
– Constant speed (n-const.)
Functions:
– Detection of thermal disinfection of the domestic hot water storage tank
– 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
– Automatic deblocking function and integrated motor protection
Display:
– Control mode
– Setpoint
– Volume flow
– Delivery head

– Power consumption
– Electric consumption
– Active influences (e.g. thermal disinfection, deaeration)
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
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
