Resideo THP9045A1023 Wire Saver
The Resideo THP9045A1023 Wire Saver is a specialized C-wire adapter designed for 1-heat/1-cool retrofit applications where the existing thermostat cable lacks a dedicated 24V common wire. By utilizing the K terminal on compatible Honeywell Home thermostats, including the RedLINK 8000 series and THX9000 Series, this module effectively splits the signal at the air handler or furnace. This allows a single conductor to manage both fan and compressor relay signals, freeing up a wire to serve as the common power source required for modern Wi-Fi and smart thermostat installation.
For service technicians, this module eliminates the labor-intensive process of pulling new thermostat wiring through finished walls. The THP9045A1023 features easy-push terminals for secure, tool-free connections and can be mounted in any orientation near the HVAC equipment’s control board. It is specifically engineered to support 24V common wire requirements without sacrificing independent fan control, making it a critical tool for upgrading older HVAC systems to high-performance digital controls.
Key Benefits- Eliminates New Wire Pulls: Provides a reliable C-wire solution for 4-wire cables, saving significant time on retrofit jobs.
- Advanced Signal Management: Uses the K terminal to multiplex fan (G) and compressor (Y) signals over a single lead.
- Broad Compatibility: Seamlessly integrates with Honeywell Prestige, VisionPro, and T-Series Wi-Fi thermostats.
- Technical Reliability: Rugged design intended for HVACR contractor use in residential and light commercial equipment environments.
- Flexible Mounting: The gray housing is compact and designed for easy attachment to or near the furnace cabinet.
Which systems are compatible with this wiring module?
This module is designed for conventional 1H/1C and heat pump systems. It is specifically intended for use with THX9000 series thermostats and other Honeywell Home models featuring a K terminal. It is not compatible with heat-only (2-wire) applications.
Does this module replace the need for a C-wire?
Technically, it creates a common wire path by reconfiguring how the existing conductors transmit signals. One physical wire is converted to provide the constant 24V power (C) needed for the thermostat’s internal logic and display.
Can I use this with two-transformer systems?
Yes, the THP9045A1023 can be integrated into systems with separate heating and cooling transformers; however, careful attention to the wiring module diagram is required to ensure the R and C legs are properly referenced.
