SCC Inc. Page 1 Section 1
1-1: Introduction
The LMV5 Burner / Boiler Management System (BMS) is ideally suited for use with steam
boilers, hot water boilers, thermal fluid heaters, and industrial burners. The LMV5 is e tremely
fle ible, and encompasses the following features:
• Flame safeguard (independent processor)
• Fuel-air ratio control
• Load control / full PID control for pressure or temperature
• Integrated O2 trim
• Variable Frequency Drive (VFD) control
• Fuel usage monitoring
• Efficiency monitoring
• Simultaneous operation of up to 5 rotary actuators (up to 6 connected)
• Dual setpoints
• Modbus communication
• Remote setpoint or remote firing rate from building automation or e ternal controller
• Flue gas recirculation hold functions (LMV52)
• Thermal shock protection
• Valve proving / valve leak testing
• Dual flame scanner options
