Resideo HPZC104 Controller
The Resideo HPZC104 is a professional-grade four zone valve controller designed to streamline hydronic zoning for residential and light commercial boiler systems. Engineered with a familiar board layout that eliminates the learning curve for experienced techs, this hydronic zone panel simplifies the wiring of up to four 24V zone valves. It features a robust 40VA transformer and independent C-terminals for every thermostat connection, ensuring full compatibility with modern WiFi smart thermostats and power-stealing models. The integrated priority zone control allows for seamless domestic hot water (DHW) integration, ensuring the indirect tank takes precedence during high-demand cycles.
For troubleshooting efficiency, the HPZC104 utilizes advanced status LEDs that remain visible through the transparent diagnostic cover. The unit supports flexible installation with a gravity-centered hang hole and native DIN rail mounting options. With color-coded wiring terminals and a quarter-turn hinged door, this controller reduces field errors and installation time. Whether you are replacing a Taco ZVC404 or a Caleffi ZVR104, the HPZC104 provides a reliable, industry-standard solution for managing multi-zone hydronic heat distribution with specialized terminal labeling for rapid wire identification.
Key Benefits for the Job Site- Universal Thermostat Integration: Dedicated C-terminals provide stable power for WiFi thermostats without the need for external resistors or "add-a-wire" kits.
- DHW Priority Logic: Built-in 1-hour priority override prevents the house from freezing if the priority zone (indirect tank) has a stuck call or high demand.
- Contractor-Friendly Mounting: Includes a gravity-centered hang hole and is DIN rail compatible for clean, organized mechanical room setups.
- Advanced Diagnostics: External LED indicators allow for rapid system checks without removing the protective front cover.
- Electrical Protection: Features quick screw terminals and a 40VA transformer to handle multiple actuators safely.
Is the Resideo HPZC104 compatible with 3-wire and 4-wire zone valves?
Yes, the panel is designed to work with standard 2-wire, 3-wire, and 4-wire zone valves. The color-coded terminal labels specifically guide the connection of common industry valves, including Honeywell and Taco models.
Can I expand the system beyond four zones?
While the HPZC104 handles four zones natively, it can be bridged or used in conjunction with additional HPZC series panels for larger manifolds. Always calculate total VA draw when adding high-load actuators.
Does this controller support priority for a domestic hot water tank?
Yes, Zone 1 is typically designated as the priority zone. When enabled, it shuts down the other three zones to direct all boiler energy to the indirect water heater, optimizing recovery times.
