Honeywell Commercial E3SM

Honeywell E3SM is the go-to solution for reliable, energy-efficient sensing in commercial buildings. The E3SM wall-mount sensor uses BACnet and Modbus for seamless integration, supports 24VAC or 24VDC power, and replaces the older E3SB 1309A0047 with a lean, less-sensor design.

• BACnet/Modbus interoperability for reliable data sharing with modern building management systems.
• Flexible power options—supports 24VAC or 24VDC to fit your electrical setup.
• Efficient wall-mount design that simplifies installation and servicing in tight spaces.
• Lean, less-sensor footprint reduces the number of sensors required without compromising accuracy.
• Seamless replacement for E3SB 1309A0047, ensuring smooth upgrades in existing networks.

Designed for commercial building automation, the Honeywell E3SM delivers dependable performance across zones, enabling precise environmental control and optimized energy use. Ideal for HVAC monitoring, space sensing, and integrated systems, it helps facilities managers simplify deployments and improve occupant comfort.
