    Trane Heat Pump Installation Problems

    If this is what you want to call DIY and don't wish to answer, please point me in the right direction

    I had this Trane 16i installed last November. The T-Stat settings were as shown. After calling them out 2 weeks later a different tech set the T-Stat as shown. You may see why I have little, to no, confidence in the installer. After
    several calls the installer refused to come out again but said my heating bills
    where normal for the weather.I went from a 2 ton ~11 sear system to a 16+ sear 2.5/3 ton unit and my electric bill went up over 30%. The AC part of this system seems to work great and my electric bill fell ~20%. I believe the strip heaters are coming on whenever the heat comes on. I'm not sure if it's a wiring or control problem and would like any advice you may want to give. I thought it would be easiest to check the T-Stat first. Thanks

    If your energy bills for cooling are dropping and in heating are rising, I would bet that your electric heat is indeed coming on every time. Are you in a climate that is below 20 deg. for the entire winter? I would contact a contractor that is willing to work with you. Unfortunately that will come with a price tag, but so does your system being set up incorrectly. Good luck

    I'm in mid-lower Tennessee. Rarely gets to 20 but sometimes gets below zero for a short time.

    never have figured out why some people are bent on bringing the electric heat on "9" cph

    th8320 (+/-)=tcont803, if anyone else cares
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    i have to wonder are you setting the stat back during the day and then kicking up up 4 or ten degrees
    if so then you are kicking in the heaters to bring the temp up to with in 1 or 2 degrees of set point then the heatpump will take over and raise you elecrric bill acordingly
    a properly sized pump osnt ment to recover it is ment to maintain temp
    set and forget is the best way to save

    CPH = Cycles Per Hour. This is the MAX # of cycles allowed in the control algorithm. Electric heat does not have a start up cost like a compressor motor, so cycle it as often as needed to do the job. I usually set this parameter to 12.

    Didn't see a setting for 530, Adaptive Intelligent Recovery. Set that to 1 to minimize Tinknocker's concern.

    Even with AIR enabled, I tell customers to not set the set-back temp more that 4* below normal temp in the heating mode. You really arent saving that much and the system may not be able to recover from a larger setback.
    "Customer Service" is not a department, it's an attitude!
