Resideo R24AA3004 Heat Sequencer
The Resideo R24AA3004 Heat Sequencer is a field-proven solution for staging electric heating elements in furnaces and heat pump applications. This single-switch, solid-state PTC (Positive Temperature Coefficient) heater provides precise control over the timing of heating banks to prevent circuit overload and ensure consistent discharge air temperatures. Operating on a 24Vac input voltage, this sequencer features a calibrated 30-90 second on timing delay and a 1-30 second off timing delay, allowing for smooth transitional sequencing of resistive loads. Built for durability in high-demand environments, the unit is shock and vibration resistant and can be mounted in any orientation to accommodate tight cabinetry. With a 25 Amp resistive contact rating and a 14 Amp inductive contact rating at 120Vac, the R24AA3004 provides the high-amperage switching capacity needed for modern electric furnace sequencing. The terminal block features 1/4" quick-connect solder or screw type electrical connections, simplifying the installation during field service calls or full system retrofits.
Key Benefits for Technicians- Universal Compatibility: Designed to replace a broad range of OEM sequencers in residential and light commercial electric heat applications.
- PTC Reliability: The solid-state PTC heater ensures consistent timing regardless of ambient temperature fluctuations.
- Versatile Mounting: Rugged design allows for installation in any position, facilitating easier troubleshooting and part replacement.
- High Switching Capacity: Supports up to 25 Amps for heavy resistive heating elements and 14 Amps for auxiliary inductive loads.
- Secure Interfacing: 1/4 inch terminals support secure solder or screw type quick connects to ensure low-resistance electrical pathways.
What is the purpose of the 30-90 second delay on this sequencer?
The delay prevents all heating elements from energizing simultaneously, which protects the local transformer from inrush current spikes and ensures the blower motor has sufficient time to reach operational speed before the heat exchangers get too hot.
Can the R24AA3004 be used in multi-stage heating systems?
Yes, this 24 volt heat sequencer is often used alongside multiple units or multi-switch sequencers to provide staggered staging for large kW heaters, allowing for more precise temperature control and comfort.
Does this unit function correctly in cold ambient temperatures?
The R24 series is engineered with a wide operating ambient range (-40°F to 165°F), ensuring the internal timing delay remains within factory specifications even in unconditioned mechanical rooms or attics.
