Help with Thermostat wiring

[rljxxx]

I'm trying to replace a White-Rodgers 1F58-910 thermostat with a Totaline Programable

P474-1050 and need help with the wiring.

The White-Rodgers is wired as follows:

Terminal / Wire color
F / Green
V / Red also jumped to VR
Y / White
M / Yellow
R / Orange

Terminals on Totaline:

G - Fan
Y1 - Cooling
W1,O,B - Heating & Rev. Value
R - Power
C - Common
Y2 - 2nd Stage Cool
W2 - 2nd Stage Heat

I think the following is correct but I don't know where the R-Orange wire goes. From what I

have read this is for the Rev. Value. Would it also go to W1,O,B?

White-Rodgers Totaline
F - Green G - Fan
V - Red also jumped to VR R - Power
Y - White W1,O,B - Heating
M - Yellow Y2 - Cooling
R - Orange ?



thanks...

Doesn`t make sense to me, Never seen a V or VR or F , remember colors mean nothing, the last installer could have used any amount of colors, I personally, if I had limited tools or knowledge , would jump the wires one at a time to see what it controls.

example:

Touch red and green together if it powers your blower motor, then hook red to r and green to g, then touch red to yellow if you hear the compressor turn on , then attach yellow to y.

The easiest way would be to check how it is wired at the unit and duplicate at the tstat, if it is a heat pump you may have to jump y and w, doesn`t sound like it though , because you have 5 wires, orange should be hooked up to "o" unless you have a Goettl or a Rheem <some models> then you would hook it up to "b"
