What if you’re installing central air conditioning for the first time, are installing a Honeywell Prestige thermostat and don’t have enough thermostat conductor wires in the wall to do so? You’ll want this module, then. This wiring module connects to “K” terminal on Honeywell Prestige thermostats and separates into “Y” and “G” signals at furnace or air handler equipment. Intended to be used in conventional and heat pump systems requiring one wire more than is available.

it worked, but you can use the fan wire … it worked, but you can use the fan wire instead and you wont need this- no one ever tells you that.
Works perfectly, Super easy install Super easy install, read the directions carefully, and print the wiring page so you can document your current wiring, and the transfer the colored wires over to the new thermostat, and HVAC system. Someone said to watch the video, that’s too confusing, just write down the wire colors, and transfer them over. The colors don’t really matter, just connect them to the matching terminals, from the wire saver, and the thermostat, using the Rc, K, C, W/OB, and you can’t go wrong, the match terminals…
Major problem solver for 20 bucks! Works exactly as advertised. My house only had 4 wires but the Honeywell TH8110R1008 Vision Pro 8000 required a fifth blue “C” wire to use Red Link Technology. This module was easy to hook up and it solved the problem. I moved the yellow wire to the C terminal of the thermostat and the green wire to the K terminal. Thermostat is now working great with the wireless indoor temperature sensor.
