    Tstat question

    I was looking at the install guide the hvac contractor left for my t-stat on my new home. They installed the outside unit last week and have it up and running. I have the York 8t two stage heat pump and have aux strips. Is this the right stat?

    outdoor- YZH06011
    indoor- AHE60D+TXV
    Tstat- TH6220D1002


    The thermostat installed (model TH6220D1002) as part of the HVAC system is compatible with the two-stage condenser unit. The stat will run the second stage only if needed when the first stage cannot achieve the desired temperature. Thanks and let me know if you have any questions.

    Honeywell specs show 2 heat one cool heat pump or 2 heat 2 cool conventional

    So I would say no you would need to go up to the Vision Pro

    I am not familiar with the equipment, but I am with the HW stats.

    I would use the VisionPro 8000 series(or better/higher models) with the outdoor sensor.

    The vision pro looks nice but I think the 6320 will work. I'm not paying for it and just need the right one so the 2 stage will work. I guess depending on if the y or y2 is connected on the unit determines if I am currently getting stage 1 or 2?

    The aux heat is controlled by the defrost board on that heat pump.It has its own outdoor temp sensor.The 8000 series wouldn't help much if any The stat wires to the defrost board to tell it if aux heat is being called for, and the defrost board determines if its needed or not, the same as an 8000 with an outdoor sensor. .

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

    OD stat on unit is only keeping aux from coming on above its set point, or does it also lock out pump below a set point?

    Cust has a Nordyne unit that has OD snap disk type stat, but it only locks strips out above its set point so pump runs in 0 or lower along with strips.

    In that case, trying to determine if the 8000 would be more beneficial, same in this case?

    Also can be set to lock out heat pump below X temp. Although the YZH is still efficient at 0F outdoor temp.

    That defrost board also controls hot heat pump operation when wired up properly and enabled.

    For a two stage compressor should the AH blow at two different speeds?

    Thanks.

    I have not seen one of these before.

    Yes, or it wouldn't be able to dehumidify much in first stage.

    They're real nice units. The defrost board cn be intimidating when you first look at it. But its easy to set up.

    But it will change two different speeds with the ecm blower? Vs blower isn't required?

    A VS blower is best to use, as it can be slowed down in both first and second stage for better moisture removal. Along with more CFM settings then just the 5 speed settings of a X13 motor.
