• Optimized screen for better reading and handling
• Mounting in tight spaces thanks to compact construction and free-standing liquid crystal display
• Modular concept to link all conventional bus systems (e.g. e.g. Modbus, BACnet, CAN, LON, PLR)
• Guaranteed quality and reliability

Type

Wet rotor circulator pump with threaded or flanged connection, EC motor with automatic power adaptation

Application

All hot water heating systems, air conditioning installations, closed cooling circuits and industrial circulation systems.
