INTEGRATED BOILER CONTROL

The integrated boiler control monitors the status of the room thermostat, high limit switch, low water cutoff (if installed), water inlet and outlet sensors, flue gas sensor and flame sensor. It controls the operation of the circula- tor, combustion blower, gas valve and spark ignitor. The boiler control also determines the sequence of operation and timing for pre and post purge periods, trial for ignition and lock out.

The control display board provides information on boiler operation on a mode and temperature display and can be viewed, programmed and reset with specific push buttons. Diagnostic information is also provided on the display, to help determine the cause of boiler failure. (See Figure 9).
