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
