Resideo HPSR103 Switching Relay
The Resideo HPSR103 is a three-zone switching relay designed for high-performance control of hydronic heating systems. This heavy-duty relay allows for the seamless integration of three thermostats and three circulator pumps, along with a dedicated output for a boiler controller. Engineered for maximum field reliability, the HPSR103 features diagnostic LED indicators that simplify troubleshooting by providing clear status updates for each zone and the circulator relay. The unit’s internal transformer is rated for 15 VA, providing sufficient power for low-voltage control circuits while ensuring precise switching relay logic. Designed to replace multiple individual relays, it reduces wiring complexity in the mechanical room. Whether you are managing a multi-zone hydronic system or retrofitting an existing boiler setup, this zoning controller ensures consistent performance and effective power management across all connected HVAC zone controls.
Key Benefits
- Streamlined Installation: Compact design allows for professional mounting and organized conduit connections.
- Diagnostic LEDs: Immediate visual feedback on zone calls and power status reduces downtime during service calls.
- High Load Capacity: Robust internal switching handles standard circulator motor loads without external contactors.
- System Compatibility: Works effectively with most 24V thermostats and standard boiler control circuits.
Common Questions
Can the Resideo HPSR103 control more than one circulator pump per zone?
The relay is designed for one circulator per zone; however, total amperage must not exceed the individual relay or total board rating to prevent overheating.
Does this relay support priority zoning for domestic hot water?
The HPSR103 functions as a standard three-zone switching relay; if domestic hot water priority is required, ensuring proper external wiring or utilizing a priority-specific model is necessary.
How do I troubleshoot a zone that isn't activating the pump?
Check the internal LEDs; if the zone LED is lit but the pump is inactive, verify the line voltage at the circulator terminals and check for a blown fuse on the control board.
