ICM Controls ICM1503 Oil Primary, Intermittent Ignition, flame sensing circuit, 45 sec, safety switch, reset button

Intermittent Ignition Oil Primary

Honeywell OEM Replacement with 45-Second Safety Timing

ICM’s Intermittent Ignition Oil Primary Control is ideal for residential oil-fired burners used in boilers, forced air furnaces, water heaters and other oil burning appliances where pre/post-purge is not a safety requirement. It uses a C554A Cadmium Sulfide (cad cell) Flame Detector to monitor the burner flame. In the event of flame failure or flame loss, the control will shut the system down.

In the event of a lockout, pressing and holding in the red external reset button for three seconds will manually reset the safety switch. (For added safety, the button press is activated upon release to ensure that the button can not be permanently held in).

A status indicator LED on the control board indicates the function of the control and can be used to aid in testing and/or troubleshooting the control. To initiate a manual lockout of the system, press and hold the reset button when the status LED is off. There is a slight delay before the heat call is implemented. This is to verify the call is valid.
