    i won't get more technical than that in this forum!

    have your technician e-mail me

    Will do. He should get here in about 20 min. Thanks again.

    Another odd question. Sometimes, when in cooling mode and inside temp is still above the set point, the compressor will turn off and the blower will ramp down to 50% for a few minutes. Then, it will come back on, the blower ramps back up and it cools again until it reaches the set point. Is that random stopping normal? Is it possible Y1 and Y2 connections are backwards to the heat pump?

    How many times must one fix something before it is fixed?

    I just ran the tests for cooling stage 1 and cooling stage 2. In stage 1, the compressor doesnt come on. In stage 2, it does come on. If Y1 and Y2 were switched, wouldn't it still come on regardless?

    No, on yours, a Y2 call, only effects the unloader. So if Y1 is hooked up to Y2 of the OD unit, the OD won't run.
    This probably why your fan is always running.

    Thanks. My tech had an emergency and had to cancel at the last 2nd. He'll be back tomorrow evening. I'll try and point him towards what you said. Thanks again.

    Make sure he rereads both install manuals.
    Might have a few more things not wired right.

    Does that make sense?
    no it does not because, colors should stay the same for each function to avoid confusion!

    again we can't get to technical here!

    use those engineering skills, the answer is right there on the wiring diagram you listed!

    I think you are right (I know you are). I'll point it out and hope the it gets done right this time. The previous times the tech didn't have the info for the OD unit installation manual so he had to just assume it was correct. The first tech (young guy, first solo install) had installed the heat pump what looked to be correct but had installed the furnace with respect to the "conventional" labels on the EIM and not the HeatPump labels. Even I spotted that one right away.

    Thanks again everyone. I'm sure I know enough now to make sure everything gets done properly. I owe you all ice cream.

    OK, everything is wired up except the dehumidifer. The new systemis fantastic. it is barely audible in stage one cooling. stage 2 isn't bad since it doesnt run all that long. The high stage cooling CFMs are set for 1250cfm (3.0 ton HP). Even w/out connecting the DEHUM, there is no ramping profile anymore. When the thermostat calls for stage1, it goes to stage1 speed and same with stage 2. No delays other than the 30sec kick on pre run and 30 sec post kick off run.

    The best part is even w/out the dehumidification controls enabled and connected, this new system is keeping my humidity down to 37% at 78 degrees inside temperature while it is 92 degrees and 70%+ humidity outside. The comfort of the new system is fan-fricking-tastic. I doubt I'll ever have them hookup the DEHUM.

    Thanks again for all the help. Now I feel like I'm finally getting my money's worth.
