Wilo-Stratos high-efficiency pump

electronically controlled, glandless circulation pump with minimum operating costs, for pipe installation. Can be used for all HVAC applications (-10 ?C to 110 ?C). With built-in electronic power control for constant/variable differential pressure. Standard-equipped thermal insulation shells. One-button manual operation level as standard, for:
Pump On/Off
Selecting the control mode:
dp-c (differential pressure constant )
dp-v (differential pressure variable)
dp-T (differential pressure temperature-controlled) by means of IR-Monitor/IR-Module/IR-Stick, Modbus, BACnet, LON or Can
Q-Limit to restrict the maximum volume flow (setting only via IR-Stick)
Manual control mode (setting constant speed)
Automatic setback operation (self-learning)
Setpoint or speed adjustment

Graphical pump display with rotatable display horizontal and vertical module mounting, for display of:

Operating status
Control mode
Differential pressure or rotation speed setpoint
Fault and alarm signals

Synchronous motor using ECM technology with very high efficiency and high starting torque, automatic unblocking function and built-in full motor protection. Fault signal light, potential-free collective fault signal, infrared interface for wireless communication with Wilo IR-Monitor/IR-Stick operating and service device.
