I'm trying to install 2441TH thermostat at my house, but found the cable has only 3 wires (R, W, G; the old thermostat only uses two wires R+W). The wall that installs the old thermostat is close to stairs, and the stud structure is complex, so I couldn't find a way to replace the old cable with new 5-wire cable.
After searching on web, I came up with method to connect 2441TH with 3 wires, but want to confirm if that is correct.
2441TH side, wire, furnace side
24R --------- R ---------- R
W --------- W ---------- W
24COM --------- G ---------- C
Also if I like to control the fan separately, can I use the “Add-a-Wire” adapter to split W and G wire?
Thanks for your input.
