Is there a way of communicating some of these issues directly to the Carrier R&D group? Talking to a Carrier tech over the phone most likely wouldn't get the message passed on. There are some...

Thanks jrbenny.

It seems to work, the system is now adjusting the target Heat Humidity setting as required. There might however be a simpler way for this control to present itself to the users....

jrbenny,

I tried your advice, lowered the Heat Humidity setting to 3 squares and yes the Auto Heat Humidity setting finally moved below 45%!

But...when I set the Heat Humidity to 15% the...

There are 7 squares visible on both the Auto and Manual setting.

When you change from Manual to Auto you can see the setting % change from 35% to 45%, bars remain the same.

The Honeywell...

Outdoor temp is currently 31°F or about 0°C.

Outdoor sensor is installed outside in the correct position.

I have just set the Humidifier back to Auto as you suggested. The Humidity setting...

I'm having some issues with the Infinity control and the "Auto" setting of the Humidifier.

During the initial setup the Heat Humidity Setting was set at 45% in the "Auto" position. As this was...

You are exactly right! Not sure how the heat humidity mode works without a humidifier. Let us know how you do without one.

The cooling mode humidity screen actually does say "Dehumidify", Thorton...

Thorton,

The Infinity humidity settings for the heating and cooling modes are set separately.

The heating humidity may be set between 5% to 45%. It also allows the user to select the Auto mode...

The Infinity controller is quite a bit different from the Thermidistat, at least from what we users see. The humidity settings for both heat and cool are user selectable and the fan settings need to...

Thanks for the reply, appreciate it.

The reading material I have found for the Infinity controller indicates you can hook up as many as 4 remote room sensors and the system will average the temp...

Let me try this one more time....a different way.

Has anyone used the Carrier remote room sensors with the Infinity system?

Do they work well when the Infinity controller uses the average of...

We had the Infinity system installed in our new house last summer. We new the cost wouldn't allow us to put in zoning or an ERV until the spring, but we wanted the best.

The question is, would...

Sorry that should read dehumidifier not humidifier!!

Coil is CC5AXA, 2 1/2 ton, paired with a 38TDB 3ton, 58MVP 80.

Yes the low/no AC load days are a bit of an issue, but I'm not sure if a humidifier is necessary or just more knowledge of how the...

I also own an Infinity system. Whenever I put the fan on low instead of auto the humidity level increases by as much as 4% in a 4 hour time period. I'm starting to wonder if the fan being set on...

Thanks everyone for your input. It is appreciated. I don't know of anywhere else where we can find this much HVAC knowledge given so generously. Hopefully I will be able to repay somehow, someday.

Okay, now I'm confused!

Carrier 58MVP080-F, inside or outside air for combustion? Carrier manuals say outside, some installers are saying inside, others outside.

The installer of this system...

Thanks everyone for taking the time to respond.

It sounds like combustion air from the outside is the way to go. The furnace is working the way it is but I've always wondered.

The installer...

Quick question about the Carrier 58MVP combustion air setup. The furnace it replaced (4 year old Carrier builder's model) did not use outside air for combustion, so the installer did not change this...

Thanks for the response!

nascar, I believe dash is right, it was chrisp who indicated he was from the Carrier engineering group.

jrbenny, thanks for the input. What you say is pretty well what...

Hi everyone. I am a new member here as well as a new Infinity system owner of a few months.

The system consists of a 38TDB, 58MVP, Infinity D01 controller and a fan powered humidifier. The...
