Is there an issue with Daikin HVAC systems working with wireless?

9 months ago

last modified: 9 months ago

We bought a cabin that needed work. We replaced all the windows, most of the appliances, got wall mounted mini-splits for the 2nd floor bedrooms, and for the basement and first floor they installed a zoned ceiling mounted unit (Airzone DZK model AZDZKS030E4-4) in the basement and the outside unit (a heat exchanger) and since then its been issues with the zoning that took like 3 -5 visits and a few part replacements to get it working, or sort of becasue it seems like mre recently its starting to not cool adequately. We have to run the AC set at 68 deg all day and it MIGHT get to 78. But one of the MAIN things we specified when we got the estimate was that whatever usit we got HAD to be WiFi enabled. We Live 5 hrs from the cabin so we need to be able to monitor the temperature and turn it up or down. The 2nd floor WiFi units work with no issues. The unit for the 1st floor and basement have never worked and after several call ouits the tech said that they would have to contact the manufacturer, Daikin. Then after me calling back several times they said that they were told there was an upgrade and that the wireless box wont work with this model so we are waiting on a firmware or module upgrade for this issue to be fixed. This has almost been a year now and I have stayed in contact with the company as well as tried to contact Daikin. How can teh hardware all be new and not work together? If this is true what company releases something that doesnt work with current products being sold? I feel I am getting brushed off by the installer company and have nevere received a reply from Daikin. 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? We stupidly paid in full about $28k for he system so the company seems to have no sense of urgency. I dont want to let this go too far and then find out there was a statute of limitations or something that says we are now screwed. The HVAC company came highly recommended in this area of Virginia. Thanks for any and all assistance anyone can offer.

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.

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.

2ea 5 ton 16 SEER Systems in the Goodman Brand with duct systems in Tulsa from www.morrisheatandair.com would have cost no more than $30,000 for equivalent products.

They operate at 19 SEER and usually qualify for a bunch of rebates.

Is my HVAC high limit switch working or not? Two HVAC pros said it is.

WHAT IS A HIGH LIMIT SWITCH? https://www.newcentralairconditioner.com/ The high limit switch in your gas furnace is a small part with two very important jobs. This switch plays a role in the normal operation of your furnace. Turning the fan motor on and off is the high limit switch’s main job. This is the role it plays in every cycle of your furnace’s normal operation. But that’s not the only thing that the high limit switch does. It’s also safety device that helps prevent your furnace from overheating. The high limit switch consists of a long temperature-sensing probe attached to a metal mounting plate. From the mounting plate, the switch is wired to the blower fan motor and to the gas valve. The switch is generally located just past the heat exchanger. This is so that it can detect the temperature of the supply air. In other words, the air that’s about to be blown into your home.

Sizing can be less of an issue when you have multiple units. Because each unit is controlled independently, provided of course the unit itself is not over sized for the area in which it serves resulting in excessive short cycling. In your case 3 ton plus 2 ton isn't necessarily equal to 5 tons of cooling... unless you drive those thermostats really low. By having two systems with total capacity of 5 tons (which, most of the time this would be oversized for a 1700 - 1800 sq ft structure) has a few advantages. 1. You have the ability to use one system only during low heat days or set the opposing unit higher. The unit set higher only runs if load conditions warrant.... meaning if it's not hot, the thermostat controlling the unit does not call... the unit can not run without a call... 2. Utility bills can be much less... because you rarely use both systems at the same time. You run the bedroom system when you sleep, the other when you're awake. If you have a home office in one the bedrooms you may need to rethink things a bit. 3. Extra capacity for when it's hot out. When it's hot you have the capacity to cool the home. (even while entertaining guests --- additional people add heat) Remember heat waves come, heat waves go... a so call 'properly sized' AC system is essentially properly sized roughly 10% of the time... especially if that system is a single speed AC system. Alot of people I come across like to sleep cool. So for that reason I doubt I would change the configuration of the space. Once you realize what you have, the choices you make are mostly budget type concerns. Essentially a set up like this runs like a 2 stage system. This kind of subject is above the pay grade of many... choose your contractor wisely. I service the Katy, Texas area.

"Both systems(two zones) have been running well and making the house cool since the installation" You can't go by the colors of the wires - you have to trace them from the thermostat to the furnace to the condenser. The fact that both systems are working fine (7 degree drop is an hour ain't bad but you need to measure the delta for a more accurate assessment) suggests everything is OK. DON'T go changing any wires around unless you do the above. Better yet, call the guy and ask him what you asked us and ask him to take a look at it.
