So first of all does ANYONE know of some type of known wifi issue with Daikin controllers or is it all BS? and Secondly what are my options for getting this corrected?

Mini split type units regardless of brand name will have their challenges. These are almost always proprietary controlled communicating systems.

What you have is specialty equipment, with add ons in the form of proprietary zone system.

It wouldn't matter if the brand was Lennox, Trane or Carrier or some other brand--- proprietary gives you less choice forces you down a certain path.

Getting it corrected: Your installing contractor. It's specialty equipment and if I had to guess 9 out 10 companies you call out there will probably tell you to call the installing contractor. It's their baby as they say.

If it was older and out of manufacture warranty period? most will probably tell you to replace it with something else. Proprietary anything doesn't give you many options. While someone (other than your installing HVAC contractor) "could" look into fixing the the problems you have with your system... who is going to pay them? You already paid 28k so I'm sure you're in the camp of no more money? --- that put's you back to your installing contractor.

The manufacture warranty only covers the part cost nothing else. If something was done improperly that falls on installing contractor. They were paid.

I doubt if you called Daikin they would tell you any different.

High end communicating equipment such as this is a different beast to get warranty parts for. It involves in many instances getting approval before hand. Those parts aren't cheap and so getting what is commonly known as "parts changer" for these types of systems -- uh no.

This is another way that HVAC contractors have to keeping you all to themselves, unless a competitor that sells the same brand, same system is willing to look at it for? What does an outsider have to gain for a system you paid 28K to someone else that doesn't work right?

Daikin isn't paying anyone to do it. This is why service after the sale is most important part to any HVAC system.

I service the Katy, Texas area.

Hi, Lloyd,

It's tough to tell from your pictures, but it appears you may have issues with the duct work design/installation--which will affect air flow and the ability to independently control the zones. The supplies don't appear to originate from a well-designed plenum. The return-- in what appears to be an unfinished basement-- doesn't appear that it can be isolated from other returns; it will likely draw return air from the basement even when other zones are operating and the basement zone is not calling for heating/cooling. Mixing of cooler, basement return air with other zones is likely to confound control. I'd recommend having a qualified third party take a look at the system, make a list of issues, and get the installers to remedy them during the warranty period.
