Taco RPP-Z-T-075-1T2V-RP Zone Valve Control Module 3 Zones

Product Description

The TACO RPP-Z-T-075-1T2V-RP is a zone valve control module designed for hydronic heating systems supporting up to 3 zones. It accepts two-wire, three-wire, or four-wire zone valves and provides a fully fused, protected circuit for each zone. The board includes two isolated end switches and a built-in priority switch, giving installers the control architecture needed for typical priority-zone heating applications. External indicator lights deliver instant diagnostic feedback at the board, reducing troubleshooting time on service calls. UL and CSA listed for compliance with standard installation requirements.

This module is suited for residential and light commercial hydronic heating installations where multiple zone valves require centralized control. It is installed by licensed plumbers, HVAC technicians, and hydronic heating contractors working with baseboard, radiant floor, or fan-coil zone distribution systems. The PC board layout is designed to minimize wiring errors during installation, and the sturdy screw-terminal connections support reliable long-term performance in mechanical room environments.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with low-voltage hydronic control wiring. De-energize all system power before wiring the control board. Follow all applicable local codes and NEC requirements for low-voltage control wiring. Verify zone valve type and wire count before connecting to confirm compatibility with the module terminals.
