Wilo Stratos MAXO-D 50/0.5-9 -R7, Circulation Pump

Description

Wet smart pump in twin design, delivered complete with built-in motor protection, alarm output, connection 0-10 V, pump on/off, external operation indication. Equipped with permanent magnet motor, function for flow limitation and built-in frequency converter. Measurement of cooling and heating energy possible together with sensor (accessory). Energy optimization function Dynamic Adapt Plus. Together with CIF module (accessory) prepared for connection to building automation, interface CAN, LON, BACnet or Modbus.

Functions

• Heat quantity recording (with optional Wilo-media temperature sensor or analog temperature sensors, e.g. 2x PT1000 possible)
• Cooling quantity registration (with optional Wilo-media temperature sensor or analog temperature sensors, e.g. 2x PT1000 possible)
• Automatic pump shutdown when zero flow is detected (No-Flow Stop)
• Switching between heating and cooling operation (automatic, external or manual) (automatic, possible with optional Wilo-media temperature sensor)
• Adjustable flow limitation through Q-Limit function (Qmin. and Qmax.)
• Operating types twin pumps: Efficiency-optimized parallel operation for dp-c and dp-v, main/standby operation
