Resideo HPSR101 Relay
The Resideo HPSR101 Relay is a heavy-duty single zone switching relay designed for demanding hydronic heating applications and general-purpose cooling systems. Engineered to replace standard single-pole relays, this unit features a 120V input and high-performance DPDT switching capabilities. It provides reliable control for circulator pumps, boiler burners, and indirect water heaters by effectively bridging the gap between low-voltage thermostats and line-voltage equipment. The robust internal construction ensures low contact resistance, while the gold-flashed contacts provide superior reliability when switching millivolt signals or low-current electronic loads. Technicians frequently spec the HPSR101 for its versatile 1/3 HP motor rating and its ability to handle inductive loads without premature contact pitting. This electro-mechanical relay is a staple for service vans due to its universal compatibility with 2-wire and 3-wire 24V thermostats, making it the go-to solution for isolating circuits and preventing feedback in complex multi-zone manifolds.
- Heavy-Duty DPDT Contacts: Allows for simultaneous control of multiple line-voltage or low-voltage circuits.
- Universal Thermostat Compatibility: Seamlessly interfaces with 24VAC digital, mechanical, and power-stealing thermostats.
- 1/3 HP Rating: Built to handle the high inrush current of standard hydronic circulator pumps and blowers.
- Snap-Action Switching: Reduces arcing and extends the operational life of the internal coil and contact assembly.
- Compact Field Enclosure: Features multiple knockouts for easy wiring and integration into existing electrical panels.
Common Questions
Can the Resideo HPSR101 be used to control a circulator pump?
Yes, this switching relay is specifically rated for inductive motor loads up to 1/3 HP at 120V, making it ideal for standard hydronic circulators.
Does this relay support power-stealing thermostats?
The HPSR101 contains an internal transformer and circuitry designed to provide stable performance even when used with modern smart thermostats that require a C-wire or use power-stealing technology.
What is the difference between this and a standard SR501?
While both serve as single-zone relay controls, the Resideo HPSR101 is valued for its specific terminal layout and footprint, which many contractors prefer for retrofitting older Resideo or Honeywell systems.
