    One Last Time...

    The Bottom Limit Is 46%.

    If You Need To Go Below 46%, Buy A Dehumidifier Not An Air Conditioner!!!!!

    If you want to understand the Infinity logic, use the search function. I've explained it in detail in previous posts.
    Perhaps you should have read the instructions before calling.

    Was the 3 ton drive furnace set to a cfm compatible to a 2 ton condenser?

    Sounds like you have a large source of moisture infiltration. I'm thinking that every time I ask a home owner about the comfort in their house I'm told that they no longer set the stat at 72 but find that 75 or 76 is plenty comfortable. We set the cooling humidity setpoint at 48% at start up and for homes that aren't wicking moisture up through the slab into the carpet the 48% is plenty comfortable. The Infinity or any system with dehum capabilities is intended to deal with the humidity associated with normal humidity that comes with heat gain by normal means. If you have a home that has an alternate source of moisture that adds several gallons of moisture to the living conditions then I don't think you can blame it on the A/C system.
    Like Jr. Benny says get a stand alone dehumidifier and find the source of the extra high humidity.
    If you choose not to decide you still have made a choice.

    depending on how much humidity you want.

    What you can do is go into advance mode and air flow selection pick dehumidify and turn on. then cooling will be allowed to over cool the space by up to 3 degrees f if the humidity level is above the cooling humidity target setpoint. the amount of over cooling allowed varies with the dehumidification demand, the cooling demand, and the actual space temperature. More over cooling is allowed with greater dehumidification demand. When space temperature is above 75 degrees and the dehumification is high, over cooling is up to 3 degrees. You can not go below 70 degrees it safe guards unit.
    Do it right the first time.

    What if the temperature is above 70°F but below 75°F?

    I have no problem with 40 RH

    Can a Carrier Infinity knowledgeable person confirm that it truly can't be set below 46%? Or can I talk to someone at Carrier? And I apologize if someone already has given me a clear answer has it is hard to tell what knowledge level some of the statements made on here are based on. This is not really a HVAC question but a Infinity question. So no disrespect meant again.

    Thanks again,

    Keith I am in a dryer area, but our summers the humidity can get higher. I do keep my house at 40% RH in winter and will be watching to see what RH will be on next warm day.

    You can over cool till 70 degrees and then it will kick off.

    You can set up for low ambient cooling with defrost intervals timer or auto- defrost with out door control.

    What about the humidity setpoint? Does the Infinity control make any internal changes to the humidity setpoint?

    JR the guy was asking about going below 46%

    Are we splitting hairs now. I thought the question was, can I lower my humidity below 46 %. Phone Tim at indy plant and ask him. Didn't you work for Carrier.

    Alright, I'll quit messing with you.

    Look, you are all over the place. You get features of the Infinity control confused. I suggest you read through the Infinity FAQ and Infinity Troubleshooting Manuals.

    Use the search function. I've posted them on the site.

    A - The LA feature is used with the 19/21 series unit

    B - The ODT interacts with winter humidification.

    C - You can NOT set dehumidification as low as you want.

    It has been awhile.

    Ya I know it has been awhile since I put one in. But you can manipulate the humidity control through. I have done this before and it does work. My house I will check on next hot day. This week it is cool. As far as reading manual I have read more than once. I do know this controler abit. Even Carrier residential/ commercial sales team is always calling me about different features and questions. I beleive In vegas we were one of the first companies complaining about HRV control. We do like series B.
