Wilo Stratos Maxo-Z 30/0.5-8

Stratos MAXO-Z 30/0.5-12

Typekey

 Superior intelligence, unparalleled quality.

The Wilo-Stratos MAXO-Z has specifically been developed for drinking water applications and combines the innovative characteristics of the Wilo-Stratos MAXO with a stainless steel housing. The durable and hygienic material sets it apart from other domestic hot water circulators on the market.

Premium smart-pump Wilo-Stratos MAXO-Z

High-efficiency inline glandless pump with EC motor and electronic power adjustment. Can be used for drinking water, cold 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 performance adaptation 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 is detected (No-Flow Stop)
• Switchover between heating and cooling mode (automatic, external or manual)
• Adjustable volume flow limiter using the Q-Limit function (Q_min. and Q_max.)
• 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
• 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)
