- Restores proper 3-way valve sequencing and control functionality
- Includes a replacement wiring harness to eliminate aging or degraded factory wiring
- Integrated relay ensures reliable switching for the 3-way valve circuit

Application
This retrofit kit is the correct solution when servicing Weil McLain CGt boilers that predate control package CP5952944. Over time, original wiring harnesses can degrade and relay contacts can wear, leading to erratic 3-way valve behavior, improper zone sequencing, or system lockouts. By replacing both the wiring harness and relay as a matched set, technicians can confidently restore full system performance and extend the service life of the boiler.
