    Robet shaw tstat 9620 replacing with a new model
    I have a Robert Shaw 9620 7 day Programmable digital thermostat 2 heat/2 cool heat pump . We have a Goodman heat pump I want to know how to hook up this thermostat to my 7wires coming in, the 7 wires are as follows yellow blue red green white brown orange. I need to know where all these wires go to in the back of the robert shaw and if there is a jumper wire required and where they go to on the jumper one if it is needed.

    With the present tstat here is how it is attached... in which this one is a 84 25-1 Robert Shaq
    The Brown wire is not attached, the white wire goes to the w2e, the Green goes to the G, the orange wire goes to the O terminal, the yellow wire goes to the Y1 terminal, the blue wire goes to the C terminal, the Red wire goes to the R terminal and there is a jumper wire from the Y 1 to W 1. It is a stage 2 heat Pump. It is electric strip heat if this also helps
    . Thanks so much for the help really appreciate it.

    Unless your heatpump has its own transformer(and I`d say it doesn`t looking at the jumper in your old stat )you will need to jumper w1 and Y 1 or rh to rc in this tstat also
