Resideo R8239B1076 Control
The Resideo R8239B1076 Control Center is a robust solution for managing line-voltage system components in residential or light commercial HVAC systems. Designed for multi-voltage operation (120/208/240 Vac), this unit integrates a 50VA transformer and a DPDT switching relay to consolidate wiring for blowers, electronic air cleaners, and humidifiers. It is specifically engineered for systems utilizing the F50 Electronic Air Cleaner, providing a dedicated 26.5V secondary power supply to drive low-voltage control circuits while handling high-current inductive loads. The included R8222D relay ensures reliable performance under heavy starting torque, supporting 3/4 HP motors with a full load rating of 12A at 120Vac. This junction box mounted relay simplifies installation by fitting directly onto a standard 4" x 4" box, allowing technicians to centralize low voltage HVAC control and high-voltage power distribution in one durable housing. This switching relay control center is essential for vintage upgrades or new installations requiring precise sequencing of peripheral indoor air quality equipment.
Key Benefits
- Universal Voltage Compatibility: Operates on 120V, 208V, or 240V primary power for versatile field application.
- High Inductive Load Rating: Rated for 3/4 HP blower motors with a 72A locked rotor rating at 120Vac.
- Integrated Transformer: Provides 50VA of power, sufficient for multiple 24V accessories without overloading the air handler transformer.
- Streamlined Installation: Mounts on a standard 4x4 junction box with color-coded leadwires for fast HVAC wiring.
- Double Pole Double Throw (DPDT): Offers flexible switching configurations for simultaneous control of air cleaners and humidifiers.
Common Questions
Can the R8239B1076 replace a standard R8239A model?
Yes, the 'B' model includes a higher 50VA transformer capacity compared to many older 'A' variants, but always verify your specific switching action and terminal requirements before swapping.
Is this control center compatible with non-Resideo air cleaners?
While optimized for the F50 series, this DPDT relay center can control any accessory within its electrical ratings, provided the control voltage matches the 24V-26.5V secondary output.
How do I wire this for a 240V system?
The primary leads are color-coded for specific voltages; utilize the black and red leads for 240V installations, ensuring the unused white (120V) or orange (208V) leads are properly capped.
