Premium smart-pump Wilo-Stratos MAXO-Z High-efficiency in-line glandless pump with EC motor and electronic power adjustment. Can be used for drinking water, chilled water, heating water and water/glycol mixtures. Energy efficiency index (EEI) between ≤ 0.17 and ≤ 0.19 depending on pump type. Control modes: *Permanent, automatic power adjustment to system requirements without setpoint specification Wilo Dynamic Adapt plus. Up to 20% energy savings compared to dp-v control mode. *Constant temperature(T-const., factory setting) *Constant differential temperature (dT-const.) *Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple pumps (Multi-Flow Adaptation). *Constant volume flow (Q-const.) *Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator) *Constant differential pressure (dp-c) *Variable differential pressure (dp-v) with the option to set the nominal duty point *Constant speed (n-const.) *User-defined PID control Functions: *Heat quantity measurement *Cooling quantity measurement *Pump automatically deactivates when no flow rate is detected (No-Flow Stop) *Switchover between heating and cooling mode (automatic, external or manual) *Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.) *Dual-pump operations: Efficiency-optimised parallel operation for dp-c and dp-v, main and standby operation *Ability to save and restore configured pump settings (3 restoration points) *Fault and warning messages shown in plain text with advice on resolving the issue *Pump venting function for automatic venting of the rotor chamber *Automatic night setback *Automatic deblocking function and integrated full motor protection *Dry-running detection *Automatic detection of thermal disinfection (for domestic hot water circulation) in conjunction with a separate temperature sensor Display: *Control mode *Setpoint *Volume flow *Temperature *Power consumption *Electric consumption *Active influences (e.g. STOP, No-Flow Stop) Version: *2 configurable analogue inputs: 0-10 V, 2-10 V, 0-20 mA, 4-20 mA and commercially available Pt1000; +24 V DC power supply *2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection)) *2 configurable signal relays for run signals and fault messages *Slot for Wilo-CIF modules with interfaces for building automation BA (optional accessories: CIF modules Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CAN) *Wilo Net as a 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 with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction *Graphic colour display (4.3 inches) with one button manual operation level *Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface (no further accessories required) *Cable break detection when using an analogue signal (in connection with 2 – 10 V or 4 – 20 mA) *Outdoor installation with weather protection possible in accordance with the installation and operating instructions *Pre-set date and time *Thermal insulation shell for heating applications Scope of delivery: *Pump *Optimised Wilo-Connector *2x threaded cable gland M16 x 1.5 *Washers for flange screws M12 and M16 (for nominal connection diameters DN 32 to DN 65) *2x gaskets for threaded connection *Thermal insulation shell *Concise Installation and operating instructions Optional accessories: *ClimaForm cold insulation to avoid the formation of condensate *CIF module: Modbus TCP, Modbus RTU, BACnet IP, BACnet MS/TP, LON, PLR, CAN *Pt1000 (B) pipe surface contact sensor (for domestic hot water) *Pt1000 (AA) sensor for installation in immersion sleeve *Differential pressure sensor
