Wilo

Premium smart-pump Wilo-Stratos MAXO-R7

High efficiency in line glandless pump with EC motor and electronic power adjustment. Can be utilised for Cold water, heating water and water/glycol mixtures. Energy efficiency index (EEI) between š¢§ 0.17 and š¢§ 0.19 depending on pump type.

Control modes:

Permanent, automatic power adjustment to system requirements without setpoint specification Wilo - Dynamic Adapt plus (factory setting). Up to 20% energy savings compared to dp-v control mode., Constant temperature (T-const.), 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.), and User-defined PID control.

Product Functions:

Heat quantity measurement, Cooling quantity measurement, Pump automatically deactivates when no flow is detected (No-Flow Stop), Switchover between heating and cooling mode (automatic, external or manual) (automatic, possible with Stratos MAXO temperature sensor), Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.), Operating modes of twin-head pumps: 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 setback operation (possible with Stratos MAXO temperature sensor), Automatic deblocking function and integrated full motor protection, and Dry-running detection.
