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...
