Controls
Burner and safety limit controls are mounted in a control panel that is UL approved and meets NEMA 4 requirements. The panel protects against windblown dust and rain, splashing water and hose-directed water.
The burner management system uses a microprocessor to manage the burner controls and provide proper burner sequencing, ignition and flame monitoring protection. Readouts and signal lights on the face of the control panel indicate the current burner status and its operating history. If a problem occurs that causes the burner to shut down, the lights identify all switches affected by the shutdown. You can normally tell from the lights which limit switches tripped first, setting off the chain reaction that caused the shutdown.
The controls include a water high temperature backup controller and alarm switches for low and high water levels. A water level float gauge is also included. A water level float switch for controlling a solenoid-operated water inlet valve is available as an option.
