Honeywell S7999B System Display

Honeywell S7999B System Display

Function Description

The S7999B System Display reduces burner/boiler setup time by letting you create a fuel/air modulation curve (profile) for ControLinksô that allows for safe and efficient operation at all points along the modulation curve. The display uses a wizardlike process to assist you through the commissioning process.

The S7999B can be used on systems with one or two fuels and on systems with or without flue gas re-circulation (FGR)

The S7999B can monitor a single (Local) burner/boiler system or up to 99 burner/boiler systems connected via System Modbusô network. Each burner control, fuel/air ratio control, and expanded annunciator present on each burner system can be viewed individually to determine its status.

Universal Digital Controllers (UDC) can be used for several burner/boiler applications, and the S7999B can control the UDCs during their operation. Applications supported include:

• stack temperature
• water/steam PID load control
• steam/fuel flow monitoring
• thermal shock
• feed pump level control
