Infinity System Indoor Coil Temp?

[ArtMD]

Hi everyone, this is my first post, please be patient.....

I have a new Carrier Infinity system, A/C, cased coil, furnace, purifier, controller and HRV (HRV not yet connected) as listed below;

24ANA124A03
58MVC080-F-1-20
GAPAAXCC2025
SYSTXCCUID01-B
CNPVP1917ACA
HRVCCLHA1150

(My question isn't completely relevant to the entire list but I thought it worthwhile to let everyone know what I am looking at.)

My first question is; is there any way to tell the temperature of the indoor coil, or superheat temperature I gather, (from what I have read here), through the Infinity controller?

Second question; In the advanced menu under Service\AC Status\ there is a setting for Line Voltage. Could anyone tell me what this means or refers to?

Third question; Is there any way to very the amount of charge in the compressor and if it is correct, without bothering the guys with a service call?

All of the above are partly curiosity of a new owner and partly because I would like to know if the temperature of the conditioned air coming out of the vents is correct. I've had other systems in other houses and I don't remember the air being as cold as this system puts out. I mean the air is really cold!!

This is in a brand new condo bungalow, we replaced the builder furnace as soon as we moved in on the 1st of March this year, so I have nothing to compare it to. But I would still feel kind of silly asking for a service call, when there may be nothing wrong. Kind of hot here, I know they're busy!

Thanks ArtMD

Without hooking up refrigerant gauges, you could check indoor coil temp by taking air temp before and after the coil. this is your temp difference. It should be around 18 to 20. Line voltage is the high voltage supplying the unit. 208/240V usually. Will this help put your mind at ease?

"Really cold" is really good for removing moisture.

Infinity systems take care of themselves. Set your desired temp and forget it. If there is anything wrong at all, the Stat will report. If the HVAC tech screws up the install, the system will tattle on him.

I took a look at service screen of one my Infinity controllers.

1. Indoor coil temperature is available under AC Status, mine read 71 degrees.

2. Line voltage is the high voltage for the condenser, mine read 240 volts.

3. Charge pressures are not available.

I think the model number of your coil is incorrect. Also you have the 80,000 BTU furnace with the 2000 CFM fan. I am curious why you didn't get the version with the 1400 CFM fan since you only have a 2 ton condenser.

Thanks for the replies, appreciate the help.

Sorry mike_home, I missed your reply when I thanked everyone!

I believe the coil temp you are referring to is actually the outside condenser temperature, at least it always seems to be the same as the actual outside temperature reported on my Infinity controller.

I was wondering about the line voltage mostly as to why it was there and what it indicated. ie: if the reading is higher or lower than the previous day would that be indicating an issue with the system. Just checked my Line Voltage readings, it moves from 224 to 226. This is with Cool Stage Off and Fan running at Medium speed.

The coil number is I believe correct, it corresponds with the David Debien school of thought and is slightly undersized. I have had issues with previous systems and did an awful lot of reading and research before I purchased this one. I really wish he was still with us, he deserves to be in the HVAC Hall of Fame if there is one, and gave excellent advice.

The installer insisted on the 80,000 BTU Furnace as it was replacing a single speed Armstrong that was rated at 75,000 BTU. As it turns out we should probably have gone to the 60,000 BTU, it would have been more than enough for this very tightly built home and the cased coil would have fit better, I'm told.

I wanted the 20 series instead of the 14 series mainly due to the ECM motor which is 1hp in the 20 and 1/2hp in the 14. From what I read the 1hp might be overkill for this system, but it would only be pushed a bit if the system really needed it. The rest of the time it wouldn't cost much more to run on a 2 speed A/C and a 3 speed Furnace.

Thanks for your reply!

In low speed cooling mode, your supply air will be around 4 degrees cooler than in high speed cooling mode on that system.

Don't worry about your refrig. charge. Just program your Infinity control to the set point temps and times you want, and walk away and let the system do what you paid for it to do.

Art,

I read the Infinity installation guide again. I think you are right about the coil temperature. However I now realize I was reading the manual for the SYSTXCCUIZ01--B model which has the zoning features. In this model there is an option to add a LAT sensor. This sensor will read the leaving air temperature of the indoor unit. I assume this temperature is the air as it passes the coil, but I am not sure.

Like you, I have the SYSTXCCUID01--B model. The indoor coil information is not available.

I believe the line voltage is monitored for potential faults. The 24ana1 product data states the allowable voltage range is 187 - 253 volts. Last year I got a voltage fault message on one of my controllers. My contractor told me this may happen during a brown out condition. The volatge supply is going to vary a few volts during peak load times. I would not worry about it.

Your stategy on the 1 HP motor is interesting. I have been told these motors are very reliable. The 1 HP motor will use a little more power than the 1/2 HP size, but probably not a significant amount.

I have the zone system and so I was able to install sensors in the supply and return ducts to allow me to check my TD whenever I want. Drives my wife nuts when I play around with the user interface all the time but, it is nice to be able to check things. Too bad that option isnt available without zoning.
Whenever I go on a job with the Infinity/Evolution systems I always check the hours and cycles of operation between hi and low stages to determine how well the system has been performing. If the readings are somewhat close then there is an issue. My system will operate between 80-82% of the time in low stage and this is where you can check that for your info.

[ArtMD]

Thanks for the info, again I appreciate everyone's replies.

I also drive my wife nuts, she would prefer I leave it alone....unless of course she's not quite comfortable....

I have had to pretty much shut off the Dehum function, the system is incredibly efficient.

There is one thing if anyone from Carrier is listening, there should be a HIGH and LOW setting on the A/C Dehum setting. As soon as the LOW Dehum setting is reached, the Dehum function should shut down until needed again. This system in this house will take the humidity level down into the low 30's within 30 minutes.

I have to run the control humidity offsets at -4 of -5 to maintain the desired humidity setting of 48. Otherwise the Dehum kicks in and I'm in the 30's again. If the house humidity reaches the humidity set point with the offsets set where I have them, then it's okay because the house humidity is actually over what I want it to be.

Does anyone else have another way of doing this?

The idea of the stats on either side of the indoor coil is a good one, I'm sure I could find the time to walk down and check once in awhile!

Appreciate the help

Carrier Infinity system help. Hey everyone, I am curious if I can use a different controller than what is said to the correct one for my Carrier Infinity Heat pump , 25HNA636A300 , FE4ANF005000 ?(systxccuid01-b) or older version systxccuid01
any help is greatly appreciated.
