3.3 INDICATOR LIGHTS
Indicatorlightsarettedtothecontrolpanelasanadditionalaidtotheoperator.
The meaning and operating sequence of these lights is as follows:
Start / Low Water Reset
This switch is used to start the boiler and to reset the low water alarm. When the switch is pressed
to initiate the start-up sequence, the low water alarm lamp also illuminates and the low water
audible alarm sounds. Keeping the switch depressed for approximately 2 seconds cancels the low
water alarm and initiates the burner start sequence.
Illumination of this switch and sounding of the audible alarm at any other time other than at switch
on indicates that the boiler has gone to a lockout (safe condition) due to low water. Once the water
in the boiler has been restored to a safe operating level, pressing the switch will reset the controls.
Circuit On
Indicates that power is being supplied to the control panel.
Low Water Alarm (1st. low water).

Low Water Reset (2nd low water).
The 1st. low water light and alarm are replaced by the 2nd. low water light and a continuous
alarm, indicated by the low water reset switch.
