WILO Stratos MAXO-D 50 / 0.5-16 R7 340mm without temperature sensor

The Stratos MAXO-R7 does not have an integrated temperature sensor.

This results in functional differences compared to Stratos MAXO pumps with integrated temperature sensor.

Highly efficient inline wet running pump with EC motor and electronic power adjustment. Can be used for heating water, cold water and water / glycol mixtures. Energy efficiency index (EEI) according to pump type between ≤ 0.17 and ≤ 0.19.

Regulatory modes:

• Permanent, automatic power adjustment to the device requirements without entering the Wilo-Dynamic Adapt plus setpoint (factory setting). Current savings of up to 20% compared to dp-v control mode.
• Constant temperature (T-const.)
• Constant temperature difference (dT-const.)
• Optimization of the pumped quantity of the feed pump as required by connection and communication with several pumps (Multi-Flow Adaptation).
• Constant pumped quantity (Q-const.)
• Control according to the differential pressure dp-c at a remote point in the pipeline network (wrong point regulation)
• Constant differential pressure (dp-c)
• Variable differential pressure (dp-v) with optional input of nominal operating points
• Constant speed (n-const.)
• User-defined PID control

Function:

• Records of the amount of heat
• Records of the amount of cold
• Automatic pump shutdown when No-Flow Stop is detected
• Switching between heating and cooling operation (automatic, external or manual) (automatic, possible with Stratos MAXO temperature sensor)
• Adjustable pump power limitation with Q-Limit function (Qmin. And Qmax.)
• Dual pump operating modes: Parallel operation with effect optimization for dp-c and dp-v, main / backup mode
• Save and restore configured pump settings (3 restore points)
• Display of the fault / warning message in block letters, including recommendations for remediation
• Venting function for automatic ventilation of the rotor chamber
• Automatic attenuation mode (possible with Stratos MAXO temperature sensor)
• Automatic unlocking function and integrated full motor protection
• Dry running detection
