Section 1-1: Overview
The LMV3 Burner Boiler Management System (BMS) is ideally suited for use with steam
boilers, hot water boilers, thermal fluid heaters, and industrial burners. The LMV3 is extremely
flexible, and encompasses the following features:
• Flame safeguard (independent processor)
• Fuel-air ratio control
• Variable Frequency Drive (VFD) control
• Fuel usage monitoring
• Simultaneous operation of up to 2 rotary actuators (up to 3 connected)
• Dual fuel switchover
• Modbus communication
• Remote firing rate from building automation or external controller
• Valve proving valve leak testing
