    Wiring from Janitrol hpt 18-60 to Robertshaw 9420
    I have 5 wires going to the Janitrol thermostat as follows:
    Y = yellow
    G = green
    R = red
    O = white
    E = blue
    C = nothing
    E jumpered to W2 with copper wire

    Can someone help me with which wires go where on the new Robertshaw 9420 Thermostat? Does anything need to be jumpered? My heat pump is a Goodman 2 1/2 ton self contained unit. Any help greatly appreciated.
