Carrier Infinity control lowest humidity setting 46%

[jrbenny]

You have a variable drive compressor. Different beast.

Just have to go into advanced options and put in manual settings instead of auto tracking out door settings. When you have it in auto setting you can only adjust range which is a small margin, that is where you see bars. You can actually set as low as you want.

Auto Tracking with ODT is for heating humidification.

Just say no to droop. A dehumidifier does not sweaty ducts make.

I noticed the same issue with my Infinity system which has a variable speed motor. What ever you try, it cannot be set lower than 46% in any configuration including non auto. I recently purchased a stand alone dehumidifer to help control humidity in my basement in the early summer months before the cooling season starts in earnest.

As I look threw the product data I dont see any information, ill keep an eye open to see if i can find any info.

When you take this system below 46% rh and 70F, you are entering low ambient operations.

Your system is not designed to operate in this manner.

Buy a dehumidifier. Seal your home.

acmanhoney, When I set it to 46% and the dehumidify is set on, no it does not cool beyond the set temp. It should, but it turns off at the set temp. I wonder if it has a differential humidity difference that says it is close enough? It was just installed and the Puron pressure was calibrated. How can I tell if I have a leak?

jrbenny, The system temp is set for 78F, not 70 nor has been 70 when it limited me to 46%. Are you saying it limits me to 46% in case it hits 70? Then why not limit me to 50% in case it might drop to 65F?

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 can get you just about any information on the infinity systems but allot of times the product data is...somewhat Baud , I would have to speak to technical support and see what they say...may take me a day or so to get a straight answer but ill see what I can do.

*Edit*
Do you happen to have the full model number of your controler. Carrier has came out with a couple different models over the past 3 or so years

[beenthere]

Jrbenny use to be a Carrier rep.
I would think he is giving you the correct info.

[OldSoCalCondo]

Oh, and Carriers marketing says things like:

"Superior humidity control" - For Infinity AC.
"Infinity™ Control—you have precise control over temperature, humidity, ..." - For the T-stat.

"IdealHumidity
Keeping your home comfortable at any temperature
IdealHumidity

Innovative Carrier IdealHumidity™ systems constantly control both temperature and humidity, day and night, in any season. With an IdealHumidity system, you can monitor and adjust your home's humidity level even when your home comfort system isn't actively heating or cooling. Maintaining the proper balance of moisture in your home keeps you more comfortable at higher temperatures in the summer and lower temperatures in the winter.

In the summer, Carrier variable-speed blower systems work in concert with Carrier's highly refined Thermidistat™ Control to remove up to 30 times more moisture than a standard system, keeping you cool and more comfortable. Plus, it can also save you up to 21% in cooling costs."

IdealHumidity doesn't say it will add humidity it just says it will remove up to 30 times more then a standard system. Well I have that variable speed blower.

This all points a pretty strong picture that it will do a superior job of controlling humidity. I don't think any one would think the lowest setting of 46% is superior.

Thanks jrbenny, let me know what you think and how sure you are. This is an important issue for me so I do appreciate the help. Thanks beenthere for letting me know jrbenny's background, that helps.

Hartmizle, thanks, I would appreciate that a lot. Below are all my system details.

Carrier Condenser - 24ANA724A003
Carrier Furnace - 58CVX070112
Carrier Coil - CNPVP2414ACA
Infinity Control - SYSTXCCUID01-B
Software Version - CESR131339-13


Thanks again.

Waiting for a response back from Tech Support

If you want to change the way cooling dehumidification is
controlled, scroll to DEHUMIDIFY. You will have two options.
OFF – The system will not activate the cooling equipment to
dehumidify if the cooling temperature has been satisfied.
ON – The system dehumidifies by activating the cooling
equipment – even after the cooling temperature has been
satisfied. The system will not cool to dehumidify below 70° F
in order to protect equipment.Your air conditioning system will provide excellent
humidification control with DEHUMIDIFY set to either ON or OFF.
However, you will receive better humidification control with
the ON setting.

You may already have this information but its the only thing I found worth posting for the time being.
