Description
The Lennox 66C67 DPDT Blower Relay is a control component used to direct electrical power to blower motor circuits during heating and cooling cycles. It operates by switching between connected contacts in response to a 24V control input allowing the system to manage fan operation based on conditions. Frequently integrated into HVAC systems, this relay assists with timed airflow management and electrical routing between connected components. Positioned within the units variable section, it helps maintain consistent blower supports circuit isolation, and enables smooth transition between operating modes.
