Just purchased a Daiken Fit 5 ton unit furnace and air handler yesterday. Your explanation of the maintenance side of the thermostat was OUTSTANDING! I always like to know a little about the installer settings of the system. You were fantastic. In Oklahoma City temp is 105 today and system doesn't look like it wants to keep up. Spent $17500 on all new Daiken Fit ac , furnace and air handler.

[@a..c1241]

How did your contractor go about sizing your system? I don’t mean to sound negative, but I’ve heard that 5-ton is rarely the right answer. If you really need that much heating and cooling you’re likely better served by two smaller systems. Then again, 105 is really hot!

Great video!!..Just had a error on the one installed yesterday..these stats are new to me..Thanks again!

[@ronnygrochowski9953]

Great video thank you need to learn the whole Daikin line of products very impressed so far thank you sir

Thank you Ted

Fantastic video! Thank you so much for posting this and your other videos. Struggling with getting my Daikin One dailed in. It is hotter than the sun here in the Tampa area. I have a 3-ton unit in a 1278sqft home. Current settings are -5 on cooling high trim and +5 on cooling low trim. Dehumidification is set to "standard" and cool profile is set to "D". The house is still humid and warm. During the day we keep it set to 76 but the house is usally hovering around 78 with 58-62% humidity. Is there any other setting(s) I should change or adjust? I appreciate any insight. Local techs are little to no help.

Thank you for this thorough explanation. I'm based in South Florida and just had a new 5 ton Fit system installed a few days ago. I realized that the temp readout on the One Touch was off as we were not comfortable and used 2 source temp/humidity gages I purchased online to verify. The system wasn't cooling as low as we desired and the tech showed how he was compensating for this delta using his gage. Unfortunately, there was a lag in his reading and not certain if the offsets were exactly correct. I reset the calibration based on an average of 8-10 readings on both gages ( +1 F and and -3%RH) and the One Touch over a 24 hr period. On average, the Daikin read 75 deg F and 53.6% RH. The 2 independent gages read 76.1 and 77 deg F, and RH of 48.3% and 49.9%. My question is: I did not waiting 30 mins as you stated in your video before adjusting the offsets. Would that cause any issues?

[@thedude2897]

I don't know if he'll reply, but I've had the one plus for a good year. It took several adjustments and dealer visits to get it working right. I'm in Florida too. If you don't wait 30 mins the thermostat may read wrong. I've run into that. I want to upgrade to the one touch thermostat, but I'm scared to lol

[@lindacottle6398]

Hello I really appreciate your thorough explanation of this thermostat. I recently bought a heat pump with the newest thermostat, and many of these features that you have shown or not on the new one. Theres a lot less options and it’s a little frustrating. There are no new videos on this new smart, one thermostat from Daikin. Maybe you could upload one? Thank you

[@Zelko0925]

Great Video first one that showed the detailed options behind the menus...Coming form a Eco Bee this thermostat is not very easy unit to program even for an engineer...The Daikin One Fit, I am running has been a blessing compared to the TRANE TRASH here in Central Florida Sun... The things that are still a mystery are the Dehumidification settings suggestions .. Seems to be 5 choices no dehumidification and Standard dehumidification and then A B C profiles.. No clue what they do in terms of system operation, no place in literature left behind does it explain impact of each setting. I read the line verbiage of each option on thermostat menu... Right now the unit is running profile D on COOLING and Installer enabled profile C on dehumidification no idea why? that what he was told? I think the unit is smarter than some of these techs...any suggestions where I can find guidelines be appreciated...l These units are far the best on the market I just wish they are a bit more technology friendly in terms of programing...

[@user-oy6sy4pm9x]

I agree with the others that this is a great and informative video and that it is very hard to find information regarding the dealer settings on this unit. It seems like most dealers just leave it how it comes. I installed two new Daikin fits in my home, one on each floor, and have some questions. Overall they are running well but I have the humidity set at a 40 to 55 target and sometimes they’re hovering in the high 50s. I have not messed with any of the trims under the cooling section. The cooling profile is set on D, which I think is the one that best lets the inverter use all of the variable speed ability. The dehumidification is set to on and standard. I noticed there is an A, B, and C as well. Should I choose one of those for better dehumidification? If so, which? Setting A looks like a gives the most range. Will these affect the longevity of the unit or it’s electric energy efficiency? I also have not used the over cool to dehumidify function. With that on, once it reaches the temperature setpoint, but not the humidity setpoint, does it just keep cooling normally or does it change somehow to do more dehumidification without making it that much colder. What I’m concerned about with this function is that it will get too cold in the house while trying to reach the humidity level. Also, how does the setting where you tell the unit the square feet of the house affect anything? I have two units, one on each floor. Do I put the total house square footage on both units or the square footage of each floor on its respective unit? Again, thanks for all your help. I’m hoping you can answer some of these questions. I do like the system, and it’s cooling the house very well, but I would like to figure out how to lower the humidity while still enjoying better energy efficiency than my old unit. Thanks!

Hello, I have a Daiken 4 Ton DX17vss481ba outside and a DV48fecd14 inside (installed 9/2023. The evap coil started dripping water to the floor under the unit. I have had techs out, the coil is clean, the charge is correct but i have high static pressure due to old metal duct work in my home. Never an issue with conventual AC's in the past however with the constant ramping up and down of the inverter technology this has begun. Temp at the top of the air handler (measured at the base of the ductwork exiting the cabinet is 56 degrees). All ducts in the home are open...curious how you would program the thermostat to prevent the drip that occurs I believe at lower fan speeds. I would prefer not to have to replace all of the ductwork in this 1955 home :). Unfortunately not many techs are experts w these systems. Thank you!

[@scottbenton1314]

What additional steps are needed to commission this with dual fuel with the heat pump set as primary heat source?

[@benproutey3428]

I have a Daikin Ducted mini. The thermostat shows the temperature at the air handler. Is there a way to make it read at the wall thermostat?

[@machaf]

How did you wire the Aux heat to the thermostat? The instructions talk about 24V AC signal must be routed through one of the aux contacts of the thermostat and the use of a SPST relay. I'm confused.

[@Mcclurecentral]

You don’t, the circuit board turns it on and off according to conditions. You just tell it there is one and size of electric heat so it knows how much airflow to increase

[@FlavioTorres]

Hello, thank you for detailed explanation. I noticed that yout air handler had a 2 hours drift from the heat pump, does it mean the air handler stays ON all the time? I got a new system and my air handler stays ON regardless the whole system is off, i usually see the outside unit fan running slow for a few minutes (2-5) throughout the day, is that normal? I built a monitoring system via Daikin One API but im unable to spot why is it running. Appreciate your insight!

[@W8TLS]

I forgot to add. The AC unit will turn off if I pull the thermostat. I have the Daikin One thermostat.

[@W8TLS]

I have a question. I had my system put in. It is gas furnace and I have a 2 ton AC. The problem is since the dealer installed the unit the AC runs 24/7 unless I pull the outside fuses. Which I did during the winter. I have to leave the thermostat on heat during the summer months or the AC will freeze me out. If I set it to cool, It never shuts off. Is there anything I can look for? I had this system put in 2 years ago and the dealer hasn't been able to figure it out. They tried replacing the thermostat, But it still does it. I have no problems trouble shooting my system as I have worked with trouble shooting PLC's and other equipment and repairing for my work. I'm at my wits end. I don't want to have to buy another brand unit. I have the books for installing the units but have no clue what to look for on this one. Thanks.

[@rbird7193]

Do you know if I should turn dehumidification off in the cool setting when using with a whole house dehumidifier that is controlled separately? Thanks!

[@Zelko0925]

no humidity control is part of cooling

[@shanebreidenbach2295]

Great video, is there an option to use a hydronic coil for back up heat instead of electric back up and still use the daikin one controller

[@hvaciswin723]

Yes there is one word of caution adding a hot water coil can add to much static pressure to tge duct system so duct sizing would have to be addressed

[@hvaciswin723]

The lastest update must have corrected that. Thanks for the feed back

[@jackrobert82]

Is the Daikin fit system available now in dual fuel? I noticed you showed a setting for it on the thermostat. Associated equipment said that the fit system was not AHRI rated for the duel fuel systems at the time.

[@zachcroft6871]

I don't know who told you that; We have dual fuel up to 3ton vertical. Horizontal, and 4 and 5 ton do not rate in ahri.

[@jackrobert82]

@@zachcroft6871 this was for a 5 ton system

[@zachcroft6871]

@@jackrobert82Yes, you would be correct sir, we do not have an ahri rating for the fit at 5 ton, however, a way around that is to go with a VrV life system 1 to 1 with a furnace and VrV coil. I will have to check the AHRI rating but I want to say the last time I quoted one it was 16seer. If you have any questions feel free to call the Chattanooga branch and ask for me, I'm glad to help!

[@tekjunkie28]

Have you ever seen a Daikin fit tell the thermostat the wrong CFM?

[@hvaciswin723]

Its fairly accurate it uses input volts and amps plus motor rpm and blower wheel size to calculate cfm it gets you pretty close but not exact

[@hvaciswin723]

If cfm trims have been select it would be different than the reported number

[@tekjunkie28]

@@hvaciswin723 I don’t think so. In heating most at -10% trim then the thermostat and AHU report back 900cfm. If at 0% it reports back 1000cfm and if the HP calls for 1000 the AHU will deliver and report the same cfm.
