direct replacement for 05-326225-053, 2465H600-003. 1 try before lockout, 7 second valve trial, 24 VAC supply, enclosed board.Flame sensing is achieved through the patented technique of using the hot surface element as the sensor or, if required, a separate sensing probe maybe employed.
If after a try-for-ignition, a flame is not present, the unit goes into lock out de-energizing the gas valve automatically. Resetting after the lockout is accomplished by cycling the wall thermostat down to its lowest setting then back to the desired comfort setting. If the flame is lost during normal heat cycle, a new trial-for-ignition sequence will commence.
