Description
The ICM Controls ICM279 Post-Purge Timer Fan Blower Control Time Delay extends blower motor operation after the heating cycle ends to remove residual heat from the system and improve airflow circulation. Its adjustable time-delay control circuitry keeps the blower energized for a preset interval before automatic shutdown, allowing controlled post-purge airflow within HVAC systems such as warm air furnaces and air distribution cabinets. This timer control is wired into the blower control circuit and mounted inside the electrical compartment where delayed fan operation is required. Its timed airflow management improves heat utilization and reduces temperature buildup inside the storage unit.
