Have a Lennox Thermostat installed now, Wires read (R)=Black, (Y)=Blue, (F)=Green,
(M)=red, (Y)=Orange. I want to install a Hunter Auto Saver 550 Model # 44550.
The thermostat panel connector are in this order, W,RH,RC,G,Y/Y1,O/B
Need to know what color wire need to go on what terminal on the new Hunter.
The new Hunter said to remove the jump wire from RH to RC if there in 5 wire. I did that.
Thanks for your help

Hunter has the Auto Saver Model #44550 user manual online (http://www.hunterair.com/ssi/pdf/hunter/44550-Owners-Manual.pdf), and on page 11 you will find the chart for color coordination.
