Operating Modes

This controller supports common blower programming including:

• 20-minute automatic run cycle
• 20-minute run cycle with purge
• 30-minute automatic run cycle
• 30-minute run cycle with purge

Automatic purge cycles help remove moisture from the air plumbing after use, reducing trapped moisture and helping extend blower life.

Expert Tip from Whirly Bros

One of the most common causes of blower controller failure isn't the electronics—it's cracked pneumatic tubing or broken air fittings. Before replacing the controller, inspect the air button, tubing, and blower connections for leaks or damage. Replacing worn tubing at the same time can help ensure years of dependable operation.
