That was helpful. Thanks.

Yes it is.

Hi there. My snowmelt system is set to 12psi (50% water/ 50% glycol).

I notice when the system goes on the PSI jumps very high - well over 30psi (triggering the relief valve) if the boiler is...

Hi - in the middle of a home build and speccing out my HVAC equipment. Question for all you carrier guys:

Want to install a VanEE ERV (as opposed to the proprietary carrier). I will control the...

Everything seems to be working fine now... I'm chalking this up to the power failures / surges we had that night. Hope that is the cause!

For about 1 hour last night I received the following errors on my iComfort Wi-Fi / SLP98V combo during heating:

1. Alert ID: 114 - AC Line Frequency/Distortion Prob
2. Alert ID: 115 - Low...

I bought mine online. First one was replaced, second one the online retailer refused to replace - said it was over Lennox's 1 year warranty. My warranty booklet says 5 years. Go figure.

Anyone else having an issue with the iComfort Wifi? I've had two units die (blank screen - totally dead) inside about a year and a half.

Ok.. thanks for the reply, but I am looking for a definitive answer. Do you know for sure?

Hi,

I'm looking at the Lennox iHarmony Zoning system. I currently have an SLP98V/XC17/iComfort Wifi setup. We very much like the dehumidification feature during the summer months (the...

Interesting. Thanks for the update!

Seems like it still isn't auto-setup like the carrier option but at least we can use it now with the iComfort Wifi.

Do you have any additional information about the iComfort Zoning Panel? I have been waiting for this since the original iComfort has come out.

Thanks.

Does anyone know if Lennox will be releasing a communicating zoning system that works with the iComfort Wi-Fi and SLP98V? I would hate to give-up my iComfort Wi-Fi to use the Harmony III zoning...

Water pad is new, water is turned on and flowing (connected to hot) and winter mode is turned on. It is connected to an SLP98V so I'm thinking the low CFM and heat that is constantly runs at is not...

With my bypass humidifier dumping the humid air into the return airflow, which is then filtered by a Merv 16 air filter ... wouldn't all the humidity be caught by the filter?

I'm having a hard...

You need to re-read my question.

TB - I think you misunderstood my problem. The only way I can lower the humidity setting is by lowering the dehumidify setting (because of the deadband - but of course, de-humidify can only be...

Hi,

Does anyone know how to adjust the humidity setting when dew-point control is on? It seems that I can only adjust the dehumidify setting which will them move the humidify setting within a 5%...

So I think I've finally figured this out, with no help of the Lennox dealer.

Looked up the installation manual on the SLP98V. It clearly states that the vent from the condensate trap must not...

I had the guys come out to inspect. What a waste of two visits and $$$ for "annual cleaning". On his first visit he agreed there may be an issue with water in the inducer. He removed the inducer...

What is Load−tracking Variable Capacity?
When an SLP98 Furnace is connected to an icomfort Wi−Fi thermostat, the thermostat takes complete...

Ok thanks

Any idea what normally causes this then?

Just received this from my thermostat... I guess it related to water inside the inducer?

Dear icomfort user,

The icomfort system has generated a new alert. Below is some more detailed...

I can definitely hear some water hitting the inducer fan blades - I'm trying to figure out if this is a normal condition for these types of furnaces so I don't have my dealer come around and tinker...

Enough to hear?

I had the tech come in today. He didn't know what was causing the condensation and said he needed to circle back with lennox.

Question for the pros - should the draft inducer be totally bone dry,...

It was installed in February of this year (2012).

Hi,

Winter is coming and we have started using our furnace. I notice that our SLP98V has a gurgling noise at the fan inducer (sounds like water/condensate is swishing around in there). The...

If I use an independent ventilation controller and command it to run the infinity system by the G terminal, if the infinity system is off, won't all the zone dampers also be in the "closed" position...

I'm spec'ing the infinity because it is what I believe (after shifting through many of this forums threads) to be the best zoning system. I currently have an SLP98V with iComfort wi-fi control, and...

I emailed you back... hopefully it went through.

Actually - I don't even think I can send private messages on here. Drop me an email, tuffcalc1 AT me DOT com.

In short the home will be on a 25 x 125 lot ... essentially a 2-story box (plus...

George2 - will send you a private message.

I actually don't want the infinity system to control the ventilator. I prefer to use a non-carrier ventilator:

and...

Would love to find someone in Toronto that can design this. If anyone is interested or can provide a recommendation please let me know.

I guess the follow-up question to that is will it work if I don't connect the HRV to the infinity control. Based on my research on this site I would prefer to use the venmar platinum controller, as...

As a follow-up ... if the zoning system closes all dampers when the temperature is satisfied, what happens if I want to add an HRV/ERV to the system using the existing ductwork and interlocked to the...

For anyone with similar questions - I found the answer here:

Hi,

I'm building a new house with my wife. I am looking at the carrier infinity zoning system and am looking for clarification on how the system actually operates.

I plan on having 7 zones...

Thanks for this. I was able to go to the app store and find the app "MyInfinity" which demo's the new thermostat. I have another question about the infinity and its modulating / zoning capability. ...

Anyone know if Carrier or Bryant is coming out with a new controller soon (something similar to the iComfort Wi-Fi perhaps)?

Hi,

I am looking at purchasing a new house. To my dismay it is not a zoned system, which is the only issue I have with it. It was something I was really hoping for since our current home has...
