Premium Smart Pump Wilo-Stratos MAXO high-efficiency inline glandless pump with EC motor and electronic power adjustment. Can be used for heating water, cold water, and water/glycol mixtures. Energy Efficiency Index (EEI) between ≤ 0.17 and ≤ 0.19 depending on the pump type. Control modes: Permanent, automatic power adaptation to system requirements without setpoint specification Wilo-Dynamic Adapt plus (factory setting). Up to 20% energy saving compared to dp-v control mode. Constant temperature (T-const.). Constant differential temperature (dT-const.). Demand-driven volume flow optimisation of the feeder pump through networking and communication with multiple pumps (Multi-Flow Adaptation). Constant volume flow (Q-const.). Differential pressure control dp-c at a remote point in the pipe network (poor point control). Constant differential pressure (dp-c). Variable differential pressure (dp-v) with the option of nominal operating point input. Constant speed (n-const.). User-defined PID control. Functions: Heat quantity detection, cooling quantity detection, automatic pump shutdown upon zero-flow detection (No-Flow Stop), switching between heating and cooling mode (automatic, external or manual), adjustable volume flow limitation via QLimit function (Qmin. and Qmax.). Dual pump operating modes: Efficiency-optimised addition mode for dp-c and dp-v, main/standby mode. Saving and restoring of configured pump settings (3 restore points). Plain text fault/warning message display including remedy recommendation. Venting function for automatic de-aeration of the rotor chamber. Automatic night setback. Automatic deblocking function and integrated full motor protection. Dry-running detection. Display: Control mode, setpoint, volume flow, temperature, power consumption, electrical consumption, active influences (e.g. STOP, No-Flow Stop). Design: 2 configurable analog inputs: 0-10V, 2-10V, 0-20mA, 4-20mA and standard PT1000; power supply with +24 V DC. 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, Heating/Cooling, Manual Override (building automation disconnected), Operation Lock (button lock and remote control configuration protection)). 2 configurable relay outputs for operating and fault messages. Slot for Wilo-CIF modules with interfaces for building automation BA (Optional accessory: CIF modules Modbus RTU, BACnet MS/TP, LON, PLR). Wilo Net as Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation; dual pump operation and Wilo-Smart Gateway. Integrated temperature sensor. Automatic emergency operation in special conditions (pump speed definable) e.g. in case of bus communication failure or sensor value failure. Graphical colour display (4.3 inch) with one-button manual control level. Reading and setting of operating data as well as e.g. creation of a commissioning report via Bluetooth interface (without additional accessories) using the Wilo Assistant App. Integrated dual pump management (dual pumps are pre-wired), when using 2 single pumps as a dual pump unit, connection via WILO Net. Cable break detection for analog signal (in conjunction with 2-10V or 4-20mA). Outdoor installation with weather protection possible according to installation and operating instructions. Date and time preset. Thermal insulation shell for heating applications. 5-year warranty. Scope of delivery: Pump, optimised Wilo-Connector for all sizes the same, 2x cable glands M16 x 1.5, washers for flange screws M12 and M16 (for nominal connection sizes DN32 to DN65), 2x gaskets for threaded connection, thermal insulation shell, compact installation and operating instructions. Optional accessories: ClimaForm cooling insulation to prevent condensation, CIF module: Modbus RTU, BACnet MS/TP, LON, PLR, PT 1000 (B) pipe contact sensor (for domestic hot water), PT 1000 (AA) sensor for installation in immersion sleeve, differential pressure sensor.
