    Does not make sense to me

    In my honeywell T5 istallation it says this for heat pump
    1H/1C Heat Pump System
    R Power
    Rc [R+Rc joined by Slider Tab]
    Y Compressor contactor
    C 24VAC common
    O/B Changeover valve
    G Fan relay

    What does not make sense to me is the Rc slider. I thought that Rc was only meant or 2 stage systems

    Doesn't make sense to me either.

    If you have electric heat or furnace heat....that's not going to work.
    I wish I had a $1.00 for every response I deleted.....

    this looks like a misapplication of a thermostat and one that does not realize it yet.

    Call back tech support and tell them you have electric heat.

    That couldn't be the right t-stat if there's a secondary source of heat like a furnace, or heat strip.

    In my opinion it is not the right t-stat as a 2-1 is needed to bring on the auxiliary heat when needed as well as an actual emergency heat position.

    Wrong thermostat for your application.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Another DIY money saver that will end up calling the stat, equipment and tech support names due to THEIR own lack of understanding!!!

    Best of luck on getting this to work properly.

    A call to a competent HVAC contractor would be advised!!!!!!

    Rc and Rh are for multiple transformer systems. you used to add a jumper if only one transformer so both internal wiring circuits would be powered, they just added a switch to do that.

    I'd wonder where the W1, aux or E went to in the instruction.
