There is 4 feet under them, and just above them the walls turn to ceiling, sloped up like any cape cod.

If you're claiming it's too low then you are not hearing that when the air is moving that argument goes out the window same as it being oversized.

I can run it with a window open (simulates a larger room) and it will still heat the room exactly 6 degrees too high!!

Anyway, It doesn't seem I'm able to post a pic...but you get the idea!

Thanks!

If you look back at post #7 where I explained the heating height offset it makes more sense considering that your units are installed 4' off the ground so your overshoot is going to be worse. Sounds like your contractor sold you the wrong indoor equipment for the application. Have him ask Daikin tech support if there's a way to turn off the offset.

If there is an offset due to height why is there no problem at all in AC mode?

Also if that was the problem wouldn't turning on a fan in the room change the resulting temperature since the air is no longer stratified?

 

[Mott Rettop]

So it's clear to have nothing useful to add by calling it a dead horse...

Not one post here has even tried to explain where I'm wrong (in pointing out that height and oversize can be easily ruled out by moving air)!

In all of the cases where it's been tested with ceiling fan on and/or window cracked, it performs identically to when the room is sealed up!!!

You are just looking for someone to tell you what you want to hear, that it's all Daikin's fault. Good luck with that.

You are correct. It’s a conspiracy directed at you.

Really, pritty much everyone has said that’s the way it is. We do not have to get into the design aspect. Your install appears to be oversized and not to manufactures specifications.

Live with it or buy a different system.

The offset only comes into play in heating mode, thus "heating height offset". It's logic built into the control board that can be turned off on some units. Not sure about Daikin, but your installing contractor should be able to get that answer from their tech support.

People are giving sarcastic answers because you keep asking the same questions that have already been answered.

-It's installed outside recommended parameters
-It's likely oversized

Until those get corrected there likely won't be any satisfaction.

 

[Mott Rettop]

They informed me Daikin doesn't have a parameter they can change...if there was we wouldn't ever have had this conversation 😊

I get that it sounds like I'm beating a dead horse, but my two key points have never been refuted in the slightest...

-If it was due to air stratification then moving the air would negate that and it wouldn't be 6 degrees off any longer (but it maintains 6 degrees no matter what, tight control!)
-If it was due to it being somewhat oversized then cracking a window would simulate a larger room and it wouldn't be 6 degrees off any longer (but it maintains 6 degrees no matter what, tight control!)

As far as it being oversized isn't the biggest downside that it's just not as efficient while still trying to maintain the same setpoint as an exact size match?

Thanks!

Geez, just turn it down, 6 degrees, and carry on.

Actually I just had a thought, had a customer that complained the ducted Daikin I installed on her second floor, was running over the temp. I asked her if it was running, she said no, I told her heat rises, I can't control that. Could that be your problem, you are getting heat from down below?

 

[Mott Rettop]

It's in my Mother-in-Law's space and I need it to run in auto, no way I could explain all of the conditions/settings she would have to know to run it like that!

If it was just me, yes I agree!

 

[EugeneTheJeep]

Mother in Law? That explains the urgency. :grin2:

 

[Mott Rettop]

I tested it with the heat off downstairs too, besides that wouldn't explain how it maintains perfect control! (Just 6 degrees off)

Thanks!

 

[Mott Rettop]

Yep in general, but it turns out in my case I'm blessed, fortunately, as she's truly awesome!
