Resideo R24AA1008 Heat Sequencer
The Resideo R24AA1008 Heat Sequencer is a field-proven, solid-state solution for managing heating element staging in electric furnaces, heat pumps, and air handlers. Engineered with a positive temperature coefficient (PTC) heater, this single-switch sequencer ensures staggered activation to mitigate high inrush currents and prevent circuit overload. For crews on the job, the universal heat sequencer replacement design is a significant advantage, as it is built to cross-reference over 40 competitive models from major HVAC manufacturers.
This 24V electric heat sequencer features a reliable 1-20 second "On" delay and a 40-110 second "Off" delay, crucial for eliminating the initial blast of cold air during startup. The unit is shock and vibration resistant, allowing for stable performance in high-duty cycle residential or commercial equipment. With a 25 Amp resistive rating and 14 Amp inductive rating at 120Vac, it handles standard element loads with ease. The R24AA1008 sequencer is designed for flexible installation, featuring 1/4" quick-connect terminals and a compact frame that mounts in any position.
Key Benefits:
- Universal Compatibility: Replaces a wide range of OEM sequencers, reducing the need to carry multiple specialized parts on the truck.
- Precision Timing: Controlled sequenced switching protects heating elements and improves homeowner comfort by managing airflow timing.
- Rugged Construction: Solid-state PTC design and vibration resistance ensure longevity in demanding air handler environments.
- Flexible Installation: Professional-grade HVAC sequencer wiring is simplified via 1/4" solder or screw-type quick-connect electrical connections.
Common Questions:
How do I know if this sequencer is compatible with my furnace?
The R24AA1008 is a highly versatile component that replaces many 24V single-switch models. Check your existing part’s timing and contact ratings; if they align with the 25A resistive rating and 24Vac input, this is a standard replacement.
Can this unit be mounted horizontally?
Yes, the internal PTC heater and solid-state components allow the unit to be mounted in any orientation without affecting the timing delays or contact performance.
What is the purpose of the 40-110 second off-delay?
The off-delay ensures that the blower fan continues to run long enough to dissipate residual heat from the elements after the thermostat is satisfied, protecting the heat exchanger and maximizing efficiency.
