Resideo HPSR104 Switching Relay
The Resideo HPSR104 is a robust four-zone switching relay designed for professional hydronic applications. This 120V pump zoning panel provides precise control for up to four circulator pumps, integrating a dedicated priority zone for domestic hot water (DHW) calls. Engineered for versatility, it is fully compatible with most thermostats, including power-stealing, electromechanical, and modern smart thermostats like the T6 Pro. Each thermostat connection includes a dedicated C-terminal to simplify low-voltage wiring and ensure consistent power to connected devices.
For the field technician, the HPSR104/U features an intuitive layout with color-coded labels and a covered control board that minimizes visual clutter while providing 15 VA of transformer capacity. The LED diagnostics panel is visible with the cover on or off, allowing for rapid troubleshooting of zone activity and system power. Installation is streamlined via the gravity-centered hang hole or the included DIN rail mounting system, making it a reliable solution for complex multi-zone boiler systems.
Key Benefits- Features priority zone control to ensure domestic hot water demands are met without interference from space heating cycles.
- Includes a C-terminal for every zone, eliminating the need for external transformers when installing Wi-Fi thermostats.
- Designed with a DIN rail mounting option and a gravity-centered hanging hole for fast, level installation on any mechanical room wall.
- Equipped with an external LED display that provides real-time status of pump relays and 24V power without opening the enclosure.
- Full compatibility with power-stealing thermostats, preventing common rhythmic cycling issues found in lesser relay panels.
Is the Resideo HPSR104 compatible with Nest or Ecobee thermostats?
Yes. Because each of the four zones includes a common (C) terminal, this relay panel supports power-stealing and smart thermostats that require a constant 24V power source.
Can I use this relay for both zone valves and pumps?
The HPSR104 is specifically a switching relay for circulator pumps. If you are controlling zone valves, you should utilize the HPZC series valve controllers to match the specific voltage and end-switch requirements of those components.
How does the priority zone function during a call for heat?
When Priority Zone 4 is activated, the switching relay logic can be configured to temporarily disable Zones 1, 2, and 3. This ensures all boiler output is directed to the indirect water heater for rapid recovery.
