Maintenance-free glandless circulator with screwed connection, blocking-current proof synchronous motor according to ECM technology and built-in electronic power control for variable differential pressure control. Can be used for all heating and air-conditioning applications. Control mode can be selected in accordance with the radiator/underfloor heating application.
Standard-equipped with:
– Preselectable control modes for optimum load adjustment: Differential pressure constant (Δp-c), differential pressure variable (Δp-v), constant speed (3 pump curves)
– Integrated motor protection
– LED for setting the setpoint, displaying the current consumption in watts and the flow rate in m³/h
– Automatic deblocking function
– Manual pump venting function for venting the rotor chamber
– Manual restart
