Totaline p474-1100rec 4 wire connection

Asked Jul 8, 2010, 06:24 PM — 4 Answers
I just bought the p474-1100rec. I have four wires from wall, white, red, green and blue.
It is currently hooked up to a White Rodgers as follows:
White=W, Red=rc with a jumper to rh, green=g and blue=gas

How do I wire the p474? If I am reading it right, I should have red, white, green and yellow.

Help!

Thanks,
Phil

That is a heat pump thermostat you bought that can also be remote controlled.

What was the exact brand and model of your old thermostat. It is possible there could be some wiring problems since a heat pump requires a B terminal in somecases but also a why terminal for strait A/C usage.

Thank all for your answers. I found that I have a Lennox G60UHV X series.
From the funrance it is wired as follows White=W1, Red=R, Green=G, Blue and Red=Y2

The Therm is a model 1F86-244 The blue is attatched to the why after looking at it better
