Resideo R8285B1038 Fan Center
The Resideo R8285B1038 Fan Center provides professional-grade control for HVAC 24V systems, integrating a high-performance 40VA transformer with a DPDT switching relay. Designed for 120 Vac primary input, this unit delivers a consistent 26.5 Vac secondary output, making it an ideal solution for managing blower motors up to 3/4 HP at full load. This fan center is purpose-built for installations involving electronic air cleaners, whole-home humidifiers, and multi-speed fans where reliable switching is non-negotiable. Its heavy-duty construction ensures stable contact closure across the DPDT relay terminals, allowing for simultaneous control of high-voltage and low-voltage circuits. Mounting directly to a standard 4x4 junction box via a 1/2 inch conduit hub, the R8285B1038 simplifies field wiring while maintaining a compact footprint. For technicians seeking a robust Honeywell Home R8285B replacement, this component offers the terminal clarity and inductive load capacity required for demanding residential air handling units and furnace fan controls.
Key Benefits for Technicians:
- Universal Compatibility: Seamlessly replaces legacy R8285 series controllers in varied air handling and furnace configurations.
- High Inductive Capacity: Rated for 3/4 HP motors, providing heavy-duty switching for large blower assemblies.
- Versatile 40VA Transformer: Provides ample power for smart thermostats, humidifier solenoids, and air cleaner relays.
- DPDT Switching Logic: Dual-pole, double-throw configuration enables complex control of accessory components alongside the main blower.
- Standardized Mounting: Integrates with existing electrical boxes, reducing installation time during HVAC call-outs.
Common Questions & Technical Support:
Can the R8285B1038 handle a Nest or Ecobee thermostat?
Yes, the 40VA transformer provides sufficient current for the C-wire power requirements of most modern smart thermostats, ensuring stable operation without "power theft" issues.
What is the maximum amperage for the R8285B1038 relay?
The relay is rated for a Full Load Amperage (FLA) of 13.8A at 120V, with a Locked Rotor Amperage (LRA) of 82.8A, suitable for 3/4 HP motors.
Is this compatible with 208V or 240V systems?
No, this specific model is designed for a 120 Vac primary input. For 208/240V applications, use the appropriate R8222 or R8285 series secondary rated for those voltages.
