the Q101 protects the heat exchanger and improves airflow delivery across the coil

this unit is designed to manage multi-stage heat pumps with auxiliary heat strips

Technicians should look for a humming motor with no shaft movement

the actuator must be positioned above the valve body and never tilted more than 85 degrees from vertical

either directing it to the condenser or bypassing it to ensure optimal system performance in fluctuating ambient conditions

Advanced Distributor Products 76726700 Sequencer R-134A the Q101 protects the heatThe Advanced Distributor Products 76726700 Sequencer is a precision engineered control component designed to coordinate the electrical staging of heating elements, blowers, and compressors. By managing the power on and power off cycles, this HVAC sequencer replacement prevents sudden electrical surges that can lead to circuit breaker trips or system overloads. Built with a 24V control circuit, it features programmable delays that allow multi stage
