Resideo R8229A1021 Relay
The Resideo R8229A1021 Relay is a professional-grade electric heat relay engineered for heavy-duty load control in residential and commercial HVACR systems. As a normally closed (NC) DPST (Double Pole, Single Throw) component, this relay is designed to allow continuous load operation, providing a failsafe mechanism that maintains power to heating elements even if the control circuit or wiring fails. This makes it a critical component for electric furnace sequencers and demand management systems where reliability is non-negotiable.
Operating with a standard 24VAC coil, the R8229A1021 is a direct HN61DC024 replacement, facilitating quick field repairs without reconfiguration. Its energy-efficient design consumes zero power while the load is energized, drawing power only during the "shedding" phase to open the contacts. Constructed to withstand harsh environments, it features a wide temperature rating of -40°F to 165°F and rugged #10 combination head screw terminals for secure electrical connections with high-gauge wiring. The unit comes equipped with a universal mounting plate and additional hardware to ensure compatibility with various cabinet configurations and HVAC control panels.
Key Benefits for Taxing HVACR Applications
- Failsafe Load Continuity: Normally closed configuration ensures connected 5 kW elements continue to operate if the 24V signal is lost.
- Versatile Voltage Ratings: Rated for 7A Full Load (AFL) and 25A Resistive at 120/208/240/277 VAC, plus up to 600VAC compatibility for specialized industrial loads.
- Pilot Duty Compatibility: Can be driven directly by pilot-duty rated relays in complex multi-stage heating systems.
- Quick-Connect Flexibility: Included leadwires and hardware allow for seamless integration into Honeywell Home and Resideo legacy systems.
- Field-Proven Durability: UL and CSA recognized for long-cycle reliability in high-cycle power shedding applications.
Common Questions from the Field
Is the R8229A1021 suitable for replacing sequencers?
Yes, this switching relay is a common recontrol replacement for single or multiple element sequencers in electric furnaces, providing quiet and immediate ON/OFF switching without the delay of traditional bimetal sequencers.
What is the maximum kilowatt load this relay can handle?
In standard 240VAC configurations, each pole can typically switch a 5 kW heating element plus a fan, making it capable of managing two 5 kW elements per unit.
Why is my relay normally closed instead of normally open?
The R8229A1021 is specific for load control and energy management where the default state must be energized. It is purposefully used in systems where power is only interrupted (shed) to prevent grid overload or to prioritize other high-demand equipment.
