Honeywell 32001754-001 Relay

The Honeywell 32001754-001 Current Sensing Relay is a professional-grade solution for synchronizing accessory equipment with furnace blower operations. This HVAC current sensor is engineered to detect the electrical field of a running blower motor, allowing it to automatically energize 24V accessories such as bypass or fan-powered humidifiers. Built for high-reliability applications, the Honeywell 32001754-001 is directly compatible with the HE220, HE225, HE260, HE265, HE360, and HE365 series humidifiers. It serves as an identical technical replacement for the 32001754-001/U and A50 variants, ensuring a seamless fit for field technicians. This furnace blower relay supports both 120 Vac and 230 Vac systems, providing the versatility required for residential and light commercial HVACR setups. For motors with lower amperage draws, technicians can simply loop the common wire through the induction bracket to increase sensitivity and ensure consistent switching performance. This solid-state current sensing relay eliminates the need for complex wiring into the furnace control board's accessory terminals, streamlining on-site installations.

Key Benefits:

• Universal Application: Compatible with 120V and 230V blower motors, heat pumps, and electric furnaces for maximum field versatility.
• Precise Blower Activation: Effectively triggers accessory systems like whole-house humidifiers and electronic air cleaners only when the blower is active.
• Reliable Induction Logic: Operates by sensing the magnetic field of the motor?s common wire, requiring a minimum 4.0A load (adjustable via wire looping).
• Technical Cross-Compatibility: Confirmed direct replacement for Honeywell 32001754-001/U and A50 models.
• Space-Efficient Design: Compact form factor allows for mounting within the blower compartment or electrical cabinet with ease.

Common Questions:

Which Honeywell humidifier models use the 32001754-001?
This relay is specifically designed for the HE220, HE225, HE260, HE360, and HE365 humidifier series. It is the standard A50 current sensing relay used to interlock these units with the HVAC fan.

What is the difference between 32001754-001 and 32001754-001/U?
There is no technical difference in performance or specifications; the "/U" suffix typically denotes retail or universal packaging, while the base part number refers to the component itself.

How do I fix a relay that isn't sensing the blower motor?
If the motor draws less than 4.0A, the induction may be too weak. Loop the blower motor's common wire through the relay bracket two or more times to increase the sensed current and ensure the humidifier relay triggers correctly.
