[@ozspur]

Thank you so much for your videos. They have been a massive help. We have just bought a house in Norway and could not get the heat pump to work efficiently. Now all is good and at long last we are feeling warm in our new home.

[@johnwashburn7423]

Moved into a house that has this unit and had no idea how it worked. Thank you

Great vid same remote diff head unit well explained had unit installed mid 17 WA outback..works great in summer as we have weeks of heat in low mid forties..(110).

[@llnow1237]

This was great! Thank you for a clear explanation of the key points.

[@lumpyfarts]

Thanks very much for taking the time to make this video for us :)

[@michelenolastname]

Thank you. Couldn't find a dang thing on their website and never had a run through with contractor. Didn't even know the bottom part of the remote was under there.

[@jaaniiceee]

Me neither!! Just found out about the bottom half now

[@thromboid]

Excellent run-down, thank you! I have an older Fujitsu high-wall model (ASTA24LCC, heating output approx. 1-8 kW) which I suspect is oversized for the room(s) it is intended to heat, and it will often heat for a couple of minutes before abruptly stopping, and then won't restart for 5-7 minutes (typical compressor protection). I've thought about getting a wired remote controller/thermostat installed but for now have taken the budget option of wiring an extension onto the return/room air thermistor. The thermistor can then be positioned in a cool corner of the room or in the hallway if heating the whole house. This seems to solve the short-cycling issue, but in Heat mode it tends to overshoot the set point (had it been in Auto mode it would have switched over to cooling already). Is this normal behaviour? I'm aware there are temperature adjust jumpers on the circuit board but I'm not sure exactly what they do and in what modes they take effect. Thanks!

[@sellison899]

Thanks for the rundown! It was very helpful.

[@aminakihel1312]

Wonderful explanation 10/10 bro, keep doing this videos, it’s very useful!

[@silversong4VR]

Really enjoying these vids..so much more entertaining than the *&*&^*()(*)&*&% manual that came with the unit. I found it's doing a great job for cooling (on dry), but am finding the winter air cold so came looking for tips. Cleaned (and removed the two "extra" filters) ,changed fan mode to auto and will see if that helps. This is supposed to be my main source of heat now, but I find I'm still running a portable heater to take off the chill. Toodles!

[@mauriciomesa6455]

Excellent video, would be great if you made a video explaining how to program the weekly mode. Thanks a lot!

[@alicesmith6133]

This is the best video available for the operation of the remote. Why are temperature settings only allowed in 2 degree increments for Fahrenheit temperatures but 1 degree for temperatures in Celsius? No one seems to know the answer to this, and I seem to be the only person wondering about it.

[@rkjelsrud]

I suspect it is because the Fahrenheit scale between freezing and boiling has 180 points or degrees (212 boiling, 32 freezing) where Celsius has only 100 points or degrees (100 boiling, 0 freezing). This is a small example of why most of the world uses the metric system.

[@dougfry9949]

Awesome job! I asked the guys that installed my unit for an explanation and got the deer in the headlights look. The manual was especially confusing between energy mode and economy. One must override the other I guess. But makes sense to keep it out of economy and let the sensor do the work. At least for my use. I use mine for primarily heating a room over the garage which isn't used much to keeps the pipes from bursting. Live Northern Michigan. Does a great job.

[@leighbaker548]

I'm another owner suffering to understand the the Timer Settings, so it can go down while we're at work and in bed and come up to temperature for morning and evening meals.....tried 5 times to follow the manual and considering learning Japanese which might help me understand how they are using which terms. THIS video is great - thanks.

[@vaughanwoodruff]

+Leigh Baker Have you tried the Energy Savings Program setting that uses the motion sensor? This might be a much easier way to go that will serve you based on your occupancy rather than a set schedule.

[@Blazeyayo]

Thanks for the tips my AC is much older and same with the remote but the remote is very similar!

[@JeffBaynham]

Thank you for creating this; very helpful.

[@Tony-ej8sz]

Damn, watched right through till 12.45 because I wanted to see how to set the program, because the manual is a nightmare to try and decypher and you say go to the manual :) I am stuck with one of these heat pumps in our bedroom, but going back to Mitsubishi now because the timer is such a pain. Thanks for the video anyway.

Thanks for taking the time to make these vids. I was wondering if you could do one for programming daily ups and downs for the week. The manual is very difficult. Many thanks in advance if you can.

[@ryant75]

Thank you for your time! 😎

[@mainerforlife4887]

This is very helpful! Would you consider making a video about the timer functions? It's very confusing in the operating manual.

[@vaughanwoodruff]

+mainerforlife We'll post a link here if we make a timer video this winter. We often recommend using the Energy Savings Program feature that uses the motion sensor if it suits the needs that a timer might otherwise serve. It's much easier to program...

[@9thundercat]

As I see it, the energy savings function would be good in the summer for AC but in the winter, we tend to want to enter a warm house and the only way to do that is to program the unit to come on 60 to 90 minutes before you get home. I am waiting patiently for your vid...thanks

[@pukimaster1670]

How to setup the Timer (I struggled for nearly 2 weeks with this Timer). The manual is not very user friendly. Steps as follows: 1. Ensure unit clock is set correctly as per manual. This is the key part that I was missing 2. While the Unit is still turned on!!! Press the TIMER SETTING button (WEEKLY will begin flashing) 3. Keep pressing the SELECT button and you will step through the following modes ON, OFF, ON/OFF mode. Select the ON mode for this setup. 4. To set the time you want the heater to come on, press the NEXT button and the clock will start flashing. 5. Press the SELECT button to increase the time on the clock in 5 min intervals until you reach the desired time once you have the time that you want the heater to come on. Press the SEND. 6. The unit will shutdown and your Timer settings will be displayed on the remote control. 7. You will be able to see whether it has worked by checking the wall unit, it should have turned itself off once you pressed SEND and the vents should have closed. 8. You will see a little orange clock lit on the front panel indicating that the TIMER is active. Hope this works for you. We are still jumping around the house celebrating that we got it to work. If you have problems following this let me know.

[@vanessastraub9510]

+Puki Master I'm struggling too. Do I do the same steps to set the OFF time so it's not constantly running?

What is the lowest outside temperature you would recommend using the heat function in the winter?

[@ProductsForMen]

What does the economy mode do when you are running in DRY Mode? Thanks

[@mickfitch4581]

Excellent info thanks

[@MrPjdowns]

We just installed one in a sunroom. Our main concern is maintaining a steady temperature all day long to keep our plants happy. Would you use AUTO mode for this purpose?

[@jasonprout1974]

I wish it showed somewhere what the temperature sensor was reading. I have 9.5' ceilings, and I think it might be 72 at the unit but freezing at couch level. Wish I knew so I could either turn it up or know that it's not working properly.

[@who_cares848]

I put a Fujitsu in my house as a primary source of heat, I oversized it on purpose because I wanted to make sure it could heat my place since it gets down in the negative Temps where I am. It feels like it's always cold in my house. I have it set on 70 but it doesn't feel like 70. Is it because I'm used to forced hot water? I know hot air furnaces are similar in that aspect, always feeling cold. I'm an oil burner tech so I don't know a lot about these things.

[@flipflop3880]

We have the same one. The only thing about this pump is it doesn't have the left to right function. We are a bit upset spending the amount for this lemon

[@colecormier2797]

Great Videos! Very informative. If i happen to bend one of the fins on the coil of the outside unit, can i straighten them back out with a fine tooth comb? or will that likely do more damage?

[@insourcerenewables890]

There are special tools designed for straightening fins which are essentially fine toothed combs with the teeth properly spaced. If you google "fin comb" you'll see lots of options. If the spacing of your comb aligns with the fins you could give it a try, just be cautious.

[@colecormier2797]

Awesome. Thanks man! Great vids! Very informative.

[@karencobb2744]

What temperature is best to set the air condition on cool ?

[@luckypete0879]

Great video but I don't understand these temperatures as we are in celsius here where i live

[@bobbyfrees1925]

Yes, I have a question. Does it affect the unit or damage the unit, or create mildew if you shut off the unit after say 4 hours of running time on a daily basis?

[@LibertyDIY]

Economy mode limits the compressor to 60% (on my 09LZAS1) for heating and cooling, which increases the efficiency of the unit. So it may take longer to reach temp (or may not be able to reach temp sometimes) but will use much less electrcity overall.

[@lauraflynn2358]

Super helpful! The remote is very confusing.

[@theitfguy]

Can you program the weekly/timer function to be in economy mode.

[@neilforrest8030]

Is there a setting that allows you to allow solar gain without the unit trying to cool/adjust downward for the rise in temperature due to the sun? thanks.

[@ryankproductions7943]

great vid. do you know why I feel air coming out of the indoor unit even when its not calling for heat? I have the unit on heat and fan on auto. but with the barely luke warm air coming out kind of defeats the purpose. anyway to turn the fan right off until its calls for heat? Thanks.

[@insourcerenewables890]

+travel si When the unit is on, it will always cycle air through the fan so that it can get a temperature reading and determine whether there is a demand for heating/cooling.

[@rigakit]

+travel si The fan runs at a very low speed till the coil gets hot so its not blowing cold air until the coil warms up. if the fan never speeds up and the air is not noticeably warm you are low on refrigerant, hope this helps...

[@123ram123ram]

Great video, just messing with dry mode, I notice fan will not move from auto, and temp will go no lower than 18 celcius, roughly (68f). Thank you again.

[@vaughanwoodruff]

In dry mode, the outdoor fan and the indoor fan run at fixed speeds. The only way to vary the fan speed to remove moisture is to use cooling mode.

[@123ram123ram]

Thank you kindly Sir for your help.

[@robertpelcovits9651]

Excellent video. I took out my filters today and found mold on them. At the end of the cooling season last fall I did run the unit on fan for about 30 minutes as recommended by Fujitsu to dry out the unit. It was used occasionally during the winter for heat but not regularly. I washed the filters today with warm water which removed the obvious mold stains. Is there anything I should do to neutralize the mold? thanks

[@vaughanwoodruff]

+Robert Pelcovits You can use a mold inhibitor spray that is available for HVAC applications.

[@robertpelcovits9651]

thanks

[@atlasrn]

Spray Nine. Turn unit off, remove the dust collectors, spray the spray nine over the coils underneath the dust collectors, reinstall dust collectors, turn units on powerful. That's what I've done to prevent mold (not necessarily remove mold) during the summer when AC mode is used. It's what my installers told me to do.

[@mikelaaper9100]

Very good! I did not understand many of the functions on my remote until now

[@belmontsolar6202]

I programmed the weekly timer (thanks to KZbin) however am I correct that the unit does not show it is in weekly timer mode? So using the on off timer shows the orange timer light but the weekly timer does not show it is in timer mode. So I basically have to assume it is working?

How do you make the heat constant on 24/7? It’s cycling off and on and I don’t want that.

[@rpmmustang89]

I have a 15rls3hy 15000 unit supposedly good to -30C Had a 12000 unit previously installed and they changed it after a month as the smaller 12000 couldn't keep up in heat in my old bungalow poorly insulated. Installed the 15000 unit last winter. Seemed fine never went past 26 on the setting. This winter at the 30C setting fan on high its only getting to 20-21C 10 feet infront of the head unit. Thr kitchen right beside(open concept) is 19. This is after running almost 24 hours at around -20 outside.this unit is starting to do the same as the old 12000 unit did. On max heat setting the temps coming out of it are no always the same.i used a heat gun last year to test on the 12000 unit. Sometimes would be 30 degreesF difference coming out of the head. This makes the difference of the baseboard heaters in the house being on or off at 18C. Im starting to believe its a fujitsu issue. My buddy has a gree extreme. No issues. Ive also noticed bith these units the temp on the remote you need to increase it based on outside temperatures.never made sense to me. To keep 21-2 in house id need to change the remote setting to between 23-30C. But now on 30 it doesn't even maintain 20 threw out the ground floor of the house.

[@vaughanwoodruff]

It's difficult to diagnose from afar, but here are the points of reference we would look for if a unit was doing well last heating season but not this heating season: 1) Compare heating demand between the two years to determine whether the difference is related to the unit. 2) Check the filters. 3) Increase the temperature setting on the remote to determine whether it maintains comfort, just not at same setting (could be due to a drift in the thermistor accuracy). 4) Check pressure to see if there is a leak.

[@rpmmustang89]

I reset the remote.all good had to turn down from.max 30 to 25C within 20 mins.gained 4C in that time.we have lots of power blips.

Hello I'm new to these pumps. One of the fans the front goes up and down circulating heat great. My second fan doesn't move. How can I make my second move like the first. Thank you.

[@vaughanwoodruff]

Paul, did you resolve your issue? I'm not sure I understand the two fans you are talking about. There is one fan on the indoor unit. Some units have sweep functions that direct the fan up-and-down (and the new models left-to-right) like an oscillating fan. Is this what you are talking about?

[@katherinebohemier539]

We just recently had the fujitsu heat pumps installed in December and we are having an issue the same as a friend had where 3 lights are flashing on our down stairs basement unit. Our friend had called the service office to get someone to fix it and they had said it had to do with the timer on it and they fixed it. Both my husband and I have tried with the manual to fix this problem without any luck. There was no reason for the timer buttons to be pushed since we don't really do anything in the basement and only adjust the temperature up or down. So we don't understand why there would be a timer issue. Can you explain step by step how to fix this issue because what it says in the manual doesn't fix the problem? Thanks so much.

[@vaughanwoodruff]

If all of the lights re flashing, it indicates an error. The flashing of the lights indicates the issue. The economy light on the right will flash continuously, and the two other lights will flash in a pattern that indicates the nature of the issue. Count the number of times the operation light (green one on the left) blinks, then the number of blinks for the timer light.

[@katherinebohemier539]

@@vaughanwoodruff So after looking online to see if I could figure out what error code was happening, I did come across error code 97 to match the flashing lights, which indicates it's the outside unit. Is this something that I can fix myself with using the remote control or is it something I have to call service to come and fix? Do you know why this happened and is this a defect with the product and could happen again? We did have a blowing snow storm that happened the same evening it stopped working properly. When we got up the next morning (this past Sunday) it was cold in our basement and it didn't appear that the unit outside was plugged up with any snow. Thanks so much for any assistance you can offer.

[@juliaivy459]

I have the same system. It seems that the remote shows ONLY the temperature that I target to have, but does not show a current temperature. E.g., when I enter a cool room (obviously around 60) and turn the system on, the remote immediately shows 72 because it's my targeted temperature. How could I see a real (not targeted) temperature in the room?

[@insourcerenewables890]

Julia, the units do not have that feature. You will need an external thermometer in the room to measure the room temperature (a thermostat in the room for your other heating system might suffice). The number on the remote is a setting that targets the air temperature you are asking for.

[@cfldriven]

If your unit has wifi you can get a temperature reading by using the FGLair app.

[@billhooper5604]

We don't want to use the timer. How can we turn it off? We have the following model ASTG18KMCA.

[@rickdag1]

Is the thermostat always in the unit and not the remote on Fujitsu mini splits? Fujitsu remote seems to be line of site only, is this true? Thanks, Rick

[@vaughanwoodruff]

The unit measures the room temperature by measuring the temperature of the air entering the top of the unit. There is no "thermostat" per se; the unit runs on a program based on a variety of temperatures at the outdoor unit and the indoor unit.

[@edithmendoza7310]

Thank you for the video, it's very helpful . I have a question, I set the mode to heat up to the 88 Fahrenheit, but the air feels cool not warm. and I am not on economy mode. what should i do?

[@vaughanwoodruff]

If you have let it run for 10 minutes and still do not feel hot air, you can try a hard reset by turning the breaker to the heat pump off for 5 minutes and then turning the breaker back on. I suspect you have a refrigeration leak that will need to be repaired.

[@faithafterdark7801]

Same thing is happening to mine. It was just installed a couple days ago. The objective is to feel heat when heat is on; not cool air. I'd never buy this thing if I was a homeowner. The constant turning off, on, off again is distracting and it makes funny noises. There are cold spots in the home and it does not hear evenly. Poor people wasted their money on this thing. I'd rather use my Walmart space heater.

[@tifmcvietty7004]

My daughter just bought a home in Iowa and she has two of these units in a 750sq ft home. It is 2 degree here and the temp in the house is 57 and we have tried everything to get heat in this house and it is not working. I have to go buy two large space heaters, which we are trying now. I do not recommend these things for heat. They don't work with the temps in the midwest.

[@snapdiagnostics9989]

Hi, would you happen to know why the front door on my unit won't raise up when turned on? Many thanks.

[@vaughanwoodruff]

If it is an RLS2 model (the only model I know of that has this feature), it is likely due to a cracked gear on the intake grille cover. It is a simple fix and the part should be covered under the warranty. Call your installer or supplier ASAP.

[@jackmeoff7084]

So what is happening when the lights on the unit are flashing. I purchased a house with this unit in it and there doesn’t seem to be a users manual

[@insourcerenewables890]

That indicates an error. The two lights to the left (the green one and the amber one) blink in a code that indicate the issue. It will blink a certain number of green blinks, then a certain number of amber ones. If you still have this issue, post the pattern of blinks and we'll let you know what it is.

[@vaughanwoodruff]

You can give the unit a hard reset by turning off the main breaker for 5 minutes. If that doesn't fix it (and make sure you let it run for 10 minutes to check), you likely have bigger issues.

[@barathank]

Why does my indoor unit ASU9RLF1 green light is constantly flashing. Outside temp is 50deg with 90% humidity. The owners manual says it is defrosting, but this stays on for almost 2 days and i had to manually turn it off and on to reset and again it goes to blinking green lights.

[@vaughanwoodruff]

Did you do a hard reset at the breaker or just turn it off at the remote? If you shut the breaker off for 5 minutes and turn it back on and the unit is still exhibiting the same behavior, I would call your installer or another service professional.

Bris Edeny I’m having this problem right now!!! It’s so so cold and my heat won’t go on and it just keeps blinking economy mode. I know this was a year ago but plz tell me you found a solution

Have this system going on second year now summer time i had no problem but now in winter when i have the heat turn on it comes and after 30min it goes to slow cool fan mode and when i turn it off the green light blinks for about 5 minutes and i can only turn it back on after an hour for 20-30 before it starts doing the samething again

Sameer, what you are describing sounds like the unit running in defrost mode. See this video for more information: kzbin.info/www/bejne/enikmZ2BaNOegJY

My remote no longer seems to be transmitting a signal to my Fujitsu. Same remote as in your video. Brand new Duracell installed just now. Help?

My Fujitsu mini split operates but the flap does not go up. I’ve tried it in swing mode and the flap still doesn’t go up on its own
