    zone offsets

    Hi , I have a Carrier Infinity Zone control system . In the setup Menu there is
    a setting called Zone offset . Any one know what this does ? I have a static pressure issue and I'm wondering if this my help fix it by leaving a zone slightly opean while the other one is full opean to lower the static pressure .

    Thanks

    No, the offsets won't help.
    Perhaps you should have read the instructions before calling.

    If your running a 1.1" static with both zones open.
    You can rip out the dampers, and your system still won't be fixed.
    Your static is TOO high period. Your duct/air distribution system is TOO small period.
    Bandaids are not fixes, they just cover up the symptom sometimes.

    Think of it this way.
    You are killing you VERY VERY expensive VS blower motor. You will be paying to replace it, more then once.

    Fixing the duct/distribution system will save you money on repairs, and electrical use.
    Your VS blower is using more electric now then a standard blower would.

    static pressure issue

    So it sounds like my only recourse is to resize the ac unit furnace and condensor coil or some how increase the duct size ? Boy is this gettin to be a pain !!!

    Thanks for all the feedback

    You should get an accurate load calc done so you know what size you really need for your house.
    And then you'll know if its your ductwork that needs changed, or your unit.
