Daikin BRC1E63 controller set up field settings cycle fan off, activate sensor in wall controller

This video is about setting up a standard Daikin BRC1E63 wall mounted controller with the standard field settings we would set when connected to a ducted (Australian ducted) unit. We set the fan to cycle with the thermostat and set the to sensor location for wall controller. We also show how to adjust the fan speed settings and explain how the fan should be set up for best efficiency, effectiveness for heating and cooling operation. we show how to get into setting mode for the Daikin wall controller.

What a god send. Unit was installed by a well know company that has been in business for 50 years, yet they did not ask anything around these settings. The constant dribbling cold breeze when in heat mode is what drove me to start looking for answers & found this. Also the bit of changing the temp sensor to the controller because in summer we were freezing & had the controller temp set to 28c to try tame it. Thank you so much.

[@grahamcarruthers9337]

I found it best to keep fan running during cooling, 22 - 6, during hot weather I found the ducting can warm up in the ceiling space and when the fan turns back I will get a blast of warm air before it cools. Keeping the inside fan running prevents this and having a draft during cooling is also preferrable IMHO.

[@Greynomad1000]

Thank you - your explanation of what the codes do was very helpful. I have a Daikin ducted setup which was installed last December. At present we are experiencing some hefty frosts, down to -4. Consequently the house was very cold in the morning and the AC unit was struggling to warm it up, especially since it goes into a defrost cycle. Last night I let it run all night with a setting of 20 degrees. This morning the house was warmer but the AC had still entered a defrost cycle which may have happened several times during the night. Is it safe/sensible to let the unit run overnight in these conditions? Do I run the risk of damaging it?

[@FullyAirconditioned]

It’s fine to let them run, design to do so. Improving your insulation (heat loss) will help system and reduce running cost.

[@incompletefool9513]

Thank you for posting this information. I'm wondering if there's any way to adjust the fan speed range? Right now even the lowest fan setting is too much.

[@FullyAirconditioned]

Yes , but only if 23-6-(1-15) 1 groups the three fan speeds selectable from the controller at the lowest speeds. 15 groupe the three fan speed setting to the highest speeds. If you can only select high and low (medium is skipped) your fan is a AC fan motor, with only the few speeds.

Thank you so much! We have this unit and want to know if there is a “night mode” because that power light is so bright at night time

[@FullyAirconditioned]

Sorry I don’t think it has this function

[@FullyAirconditioned]

I was just think there may be a way, when the timer is uses there is a set temp in the off setting with a heating cooling set point. It’s set up so that if the house gets above 35 degrees the system will come on even if its set to off and in heating I think its about 5 degrees, the heating will come on even if its off at the controller. Both the heating and cooling set points can be adjusted to a higher setting for heating or lower set point for cooling. If you set this up the unit should turn on if the temp in the house drops below the set point, so the heating will start and heat your home at night with out the operation light lit. Haven’t tried it my self but I believe it will work, not to shore of the differential of the system kicking in and out, but you should be able to work this out with a bit of trial and error.

Very very helpful!! Thank you so much! One more question- The AC is too noisy in one of the bedroom but good in the others. I set the fan speed at 5 and also tried several speeds but didn't help. Is this a normal situation or if there's anything wrong with my AC?

[@FullyAirconditioned]

How long is a pice of string, there could be many factors into why it’s noise, air flow, short duct, 1st duct / closet duct to the indoor unit, restricted air flow, too much air flow 🤷‍♂️. But one thing is that it’s only that outlet, so it would be something different with just that particular duct. Check to see what difference are and maybe that will point you in the right direction.

[@aidanhaines4863]

Can you please explain what the Indoor Unit Status temperature labels are for in this setup menu. For example Th1: 22°C, Th5: 27°C etc... my indoor room temp is saying 27°C but it feels much cooler. Could it be incorrect? I have a BRC1E63 as well

[@FullyAirconditioned]

Hi Aidan, It depends on what indoor units its connected to, but on ducted systems Australia th1 is usually the suction air thermistor on the indoor unit, th2 heat exchanger liquid line indoor unit, th3 heat exchanger gas pipe indoor unit, th4 discharge air temp indoor unit, th5 could be wall controller ??, easy way to check is to blow warm in the thermistor and see if it changes.

[@FullyAirconditioned]

Hi Christian, It depends on the model of the ducted indoor unit and how new it is, with the older units they have a AC fan motor with 3 or 4 speeds (usually only 2 selectable from controller) . With the newer units they have a DC fan motor with 15 fan settings, each fan setting adjust the 3 selectable fan speeds at the controller. Yours may be an older system or it could also be a low static indoor unit that has less speeds. Kind regards Craig

Another question - thx for your answers so far. I've seen several videos explaining how to set the system to take it's operating temperatures from the controller or the the return air or alternating between the two. But no-one explains why Daikin have the different settings or which one is the best to use. Can you explain which one is best to use and why?

[@FullyAirconditioned]

Depends on the insulation application, for a office that’s need to meet the standard for introduced outside air (a conditioned office space requires 1lt/sec of outside air per m2 of floor area). The indoor fan need to run all the time to draw that air in, regardless if it heating or cooling, so measuring from the return air is more accurate. In a home this is not necessary and cycling the fan completely off to stop drafts is best. If the sensor in the return air is active (air inlet of indoor unit) and the fan is not running it’s not actually measuring the room temperature. On a cold but sunny day with a ducted system installed in the roof, the roof cavity may be quite pleasant 22 degrees, but in the house it’s only 18 degrees, if the controller was set to 21 heating, it would not turn on. So it is best to set the controller to look at the wall sensor for control for this application.

Am I using this unit properly or can you advise otherwise? Much appreciated! Thanks

[@FullyAirconditioned]

From experience leaving it on is more cost effective as the system is just ticking over and not running at full speed to raise the temp in the space. When my wife started staying home with the newborn I thought the running cost would go through the roof, but it was the same if not cheaper to run and more comfortable.

We have good northern facing glass so house gets good free heat from the sun during the day, we make shore the curtains are open during the day. At 3.00 pm the unit turn back on at 22 deg c and runs through to 10.00 pm. At 10pm it turn back down to 16 deg c and run through the night (well the system is on but it doesn’t blow any air as the fan is set to cycle off, on the real cold nights, below 0 deg c it might kick in once , twice, maybe three times during the night. So it’s not set to turn off during winter but when it’s set down to 16 deg c it hardly comes on.

Thank you. I just want to know how to turn off the AC only in some rooms while it’s on in the other areas at the same time?

[@FullyAirconditioned]

This controller cannot do that. You would need a controller that’s has zone function. Assuming it’s a ducted unit, you would need to have zone motors installed in the ductwork to the room you want to be able to turn off.

[@jaimiehenry5266]

We have a ducted system with bedroom and living room zones. There is the master control panel in the living space and a slave/sub control panel in the upstairs hallway, with the return air duct in the same upstairs hallway. Does the control panel thermistor only read the downstairs main control panel (when the field settings are changed)? Does it make more sense to use the return air temp in this case?

[@FullyAirconditioned]

When sensing from the wall controller when you have a master controller and a slave controller, the sensor will only look at the master controller. The 2nd controller is a slave controller just mimics what happening on the other controller and give you the ability to adjust settings from both controllers.

Hey there. Just got a Daikin heat pump installed (FDYA125AV1 indoor unit) and found this video. Of course I jumped in and changed all the settings (apart from the fan speed), then I read that indoor units vary and I may have messed up some setting (didn’t make a note of what I changed from). I did ask the sales person about the this and said it looked ok but he wasn’t sure about Mode 22-3 fan turning off when thermostat shuts off heat. Here comes the question.

[@mifl6739]

Hi there, I have one of these controllers, connected to a compact ceiling cassette. My observation is the system never works hard enough when I have it set to FAN AUTO mode. By that I mean it really struggles to reach the set temperature because it rarely shifts itself up beyond the lowest/quietest fan speed/power level. Is there some way in the field settings to make it more keen to shift into a 'higher gear' when in FAN AUTO mode; thus working a bit harder overall? I guess what I'm trying to say is I'd like the system overall to be more enthusiastic about ramping itself up so it can get to the set temperature faster. I had hoped your advice in this video with regard to changing the max fan speed would help, but it seems that playing with this particular field setting isn't available in my setup (I presume this is because I have a ceiling cassette and not a ducted unit).

[@FullyAirconditioned]

Hi, With the cassette systems there some field settings that can be set like high ceilings, this off sets the control temperature to compensate for high ceilings. Also there is a different code to make the sensor active in the wired remote control. See attached link drive.google.com/drive/folders/1KHh8K8Bq4G3KYqpdkkU7a4jQAMLbkU36

As for the making-the-controller-sensor-active setting being different; I just checked my system and it looks like it is already set to use the controller sensor already. Can I ask one more question? Does my particular setup offer any corresponding field settings for the turning-off-indoor-fan-when-thermostat-is-satisfied options that you go through in your video? Many thanks!

Hi Craig, the for the video. I set 22-06-03 for the compressor and fan to disable when the temp is reached however in cooling I have a set point of 23degrees and room temp of 22degrees. I have also changed the setting to read the controller temp. Any tips?

[@FullyAirconditioned]

Make sure 20-2-03 is set, also check c1-1-02 is set. Some models will all ways have some influence from the return air sensor. The only way around this is to install a remote sensor. You unplug the return thermistor, plug in the same plug on the pc board a remote sensor. You then install wall mounted sensor next to the wall controller. That’s the only way around this, there are a number of different sensors available from DAIKIN depending on the indoor model, if you get the wrong one, you can always cut the plug off the existing sensor and join the cables to the wall mounted sensor.

Hi Shaun, Good question, No they haven’t changed, codes starting with 1, ie 10 and 12 allow you to change the setting, and codes starting with 2, ie 20 and 22 are where you can view the current setting. With old controllers (about 10-20 years) you had to set the settings in the code starting with 1 and view the current settings in the codes starting with 2. You can now adjust the settings in both 1 or 2, but can only view current setting in codes starting with 2. Hopefully this is not confusing. Thanks Craig

This is brilliant. Thanks for such a clear explanation. Our Daikin unit is about 10 years old we have a BRC24Z4 type controller that you cover in another video. Are the settings the same as in this video when you access them? I am trying to work out how to adjust controller so that the fan doesn’t blow cold air for 5 minutes when we first turn the unit on before it starts blowing warm air. Is there a “pre heat” type setting?

[@FullyAirconditioned]

If your unit is 10 years old then the fan in the indoor unit is a ac fan motor, this fan only has a few speeds and there is only about 5%~10% different in air flow. When the unit starts up it will warm the indoor unit coil to about 42 deg before it turn no the fan, but the compressor is an inverter and it will take about 10 minutes to reach full speed (full heat output). This different in time is the cool air you are feeling. With the newer units the fan is a dc fan motor that has many speeds, ranging in speed from 5%~100%. The fan comes on slowly and continues to speed up as the coil increases in temperature, the end result is less cool air blowing at start up. With the brc24z4 best to set it to cycle fan off in heating and cooling, if you leave as factory set the fan will stay on all the time unless you have the fan in auto. But in auto fan it will sample the air (turn on the fan every 5 minutes for two minutes) so the return air sensor can take an air temp reading.

Also, is the BRC1E63 still the latest model? If not, do the latest controllers have any new features compared to this one? Oh & would there be anything else to know if the apartment setup was a mixture of integrated vent in a bulkhead in living room & a couple of split system units in bedrooms (with their own, zoned controllers)?

This is a difficult one as it depends on what unit this controller is connected as they all have different settings from ducted, Vrv, cassette ect. I have looked and asked the question but don’t have that information sorry. I will post the sheet that comes with the current ducted unit.

[@madeline998]

Hi Craig, would you mind telling me why my air con the one you are talking about isn’t working in the bedrooms (main bedroom working perfectly) but everywhere else in the house is? I’ve cleaned filters, changed settings. Just don’t know what else to do. It’s so hot my kids are boiling in the rooms.

[@FullyAirconditioned]

If it’s a ducted system and the air flow is not even, you won’t get an even temperature. Most common cause is bad duct design, the length of duct feeding that room is longer than the other ducts or too small for the area. The other reason could be that that actually room has a higher heat load the the other rooms (like big west facing windows)

I recently shifted to an apartment where daikin brc1e63 system is installed. I changed the settings following your video. Also, I have set fan speed to auto and set the heat (this is heat not auto node) to 18 degree as it is winters where I am staying, cool temperature is set to 27 degrees, am I setting it correctly? I am totally new to this. Please advise for any corrections in the settings I have done. Regards

[@FullyAirconditioned]

If it gets below 18 it should start heating and above 27 start cooling, in-between the two remodel it should do nothing (dead zone). I do find 18 a little too cool tho for heating but whatever you find comfortable.

[@victoriaweingartner6376]

@@FullyAirconditioned Great thank you. how quickly would you expect the system to heat up from 18 to 22degrees-3 bedroom kitchen dining and lounge 188sqm.

[@FullyAirconditioned]

That’s a hard question to answer. It depends on the size of the system and where you live (how cold it gets). I live in Canberra, it gets cold here, so when we size a system we don’t look at the capacity in the brochure as it’s measured when it’s 6 degrees outside. We refer to the engineering data book and look at the units capacity @ -5 degrees outside. As there is a large drop of in capacity at low outside temps. The daikin FDYA160 ducted system has a capacity of 18kw heating at 6 degrees outside. But that same system only has 12.9kw at -5, so it losses 5kw of performance. On top of that at -5 the system will need to go through a defrost so you loss heating for 10-15 min so there goes another 3kw of heat. So now your 18kw system is only capable of delivering 10kw of heat in 1 hour. If you needed 18kw of heat we would have sized a unit one or two sizes bigger. The FDYQ180 system has a large coil, so it’s ability to pick up heat from the air outside is very good. This unit has a rated capacity if 20kw heating and drops to 19.8kw @ -5, so it only loses 200watts. Not all units are the same and the loss differs depending on the model of unit, so it’s important for us to always look at the capacity in the engineering book for that unit. Sorry for the long answer. 😳

[@antonokmyanskiy2928]

Nice video! My MSX36 inverter always seems to run at full speed (loud) even with one FDMQ calling for 1 degree change. Any ideas why this could be? Thanks!

[@FullyAirconditioned]

The fan at full speed or the heating cooling capacity?? If it’s the fan then it depends on the fam motor type. Ac fan motors are limited to a few speeds with not a lot of difference. A dc fan motor can have many fan speeds over a very wide range.

My brand new ducted slimline premium unit was not cooling the house down in extreme weathers. I just checked the settings and it was set on 5 when it had the option on 15 now its blowing cold air must harder. Why was it set so low is that a daiken thing?

[@FullyAirconditioned]

Don’t think so as factory set is 10, if you don’t get enough air across the coil it won’t allow the compressor to fully ramp up. The compressor will only run as fast as it’s needed, with low air flow, only so much gas can evaporate off, (changing from a liquid to a vapour) the speed of the compressor is slowed down so that liquid gas doesn’t flood back to the compressor and damage it.

[@kerrynlucas9995]

Great video, My room temperature is set to 18 but the temperature is showing 23 it’s definitely not 23 we do have another weather gage which shows the room at 20. At times the system will heat to 25 even though it’s stet to no more the 20 heating. Hope you can help.

[@FullyAirconditioned]

Have you set the wall controller to be the active sensor like in the video ?? 20-2-03. Are you using the temp display on the wall controller or a different temp gauge. The system is only going to look at the active sensor to control the temp, the sensors are not always 100% accurate so you just adjust it till you feel comfortable. Is the wall controller near other heat source (like the sun or air blowing from a vent on to the sensor), is the controller on an exterior wall that cops a lot of sun.

[@user-jd9qc4dy1c]

Thanks for the informative video! I tried these settings out, and when I changed 22-3-01 to 22-3-03, and changed 22-6-02 to 22-6-03, this seems to have changed something on the compressor - it seems to step through more incremental speeds, and some of these are really quite loud and buzzy, clearly being heard from inside the house. Are these setting supposed to change the compressor settings like this? If I reset back to 22-3-01 and 22-6-02, everything goes back to normal again and the outside compressor is back to normal noise levels (i.e. not being heard from inside the house). My set up is an Australian install of a Daikin 3 phase FDYQN180LB-LY, and the outdoor unit is a RZQ180LY1, all using a BRC1E63 controller. I've tried to look up where I can find the field settings for this unit in case they're just different for this unit, but I'm having no luck at all finding them. Can you help at all please? Thanks in advance!!

[@FullyAirconditioned]

The settings are common for this unit, when you change the fan to cycle on and off with the t-stat you will need to set the sensor to the wall controller as it’s factory set to the indoor unit. If the fan cycles off, the indoor sensor is not sensing the room temperature air as there is no Air passing over it, this could be causing a big differential, and when the system starts back up, it realises that the temperature differences is wider than what it was reading, it may need to ramp up to a high-speed or over come the larger temp differential. You should set 20-2-03 sensing from wall controller only when setting the fan to cycle off. When it’s set to fan all ways being on it may be cycling the compressor more frequently at a lessor speed. But you are doing the correct thing, if it’s not how you want it change it back. You could try setting it too 22-6-01 fan set to low low speed in cooling t-stat off and keep it set to indoor unit sensor. This will drop the fan to a very low speed when the t-stat is off but keeps a small amount of air passing over the sensor in the indoor unit. Trial and error, just make a note of what it was set too original and if you’re not happy change it back.

[@user-jd9qc4dy1c]

@@FullyAirconditioned Thanks for the quick reply! Yeah, I originally tried that with 20-2-03 set too, and that’s when I encountered the problem. I tried it with 20-2-02 (the original setting) too, but it kept happening. I’ll just try going with low-low fan speed for cooling instead (22-6-03). Thanks again for the help and detailed videos!

[@Kakashi_San_1989]

Hello, I was just wondering what your recommended field setting would be for the fan on a Daikin unit in “cool” mode as the information online is very conflicting. In your video you suggest to set it to 22 6:03 (Fan shuts off when set temperature is reached), would that be your recommended setting to ensure a longer lifespan on the unit. As there are arguments for and against it, some of the information online suggest that having the fan on 22 6:02 in “cool” mode has benefits over having it set to 22 6:03. In your experience what setting ensure longevity of the unit?

[@FullyAirconditioned]

Person choose, change it and see if you like it and how the system operates, you can change it back easily. I leave on unit on from the start of summer, if the house is hot the system runs to cook it down, we have had a cool spell in the weather and the system hasn’t needed to come on for the last two days, if the fan was set to run all the time I would find it annoying. Personal choice, you can set 02 as well low low fan speed.

[@Kakashi_San_1989]

Thank you for your prompt response! Appreciate the information. Would you say one option over another ensures a longer lifespan for the unit? Or one tends to cause more issues in the long term with parts wearing out?

[@FullyAirconditioned]

@@Kakashi_San_1989 no, l can’t see one over the other having an impact on life of the unit, the quality of the installation will have the biggest effect on the life of the system than any thing else. Evacuating the system below 500 microns to ensure no oxygen or moisture exists in the refrigerant circuit and just a general quantity insulation. That’s the biggest cause of premature failure of a system. Using cert three in refrigeration air conditioning trade and not a cert 2 installer, one is a 4 year apprenticeship and the others a 2 day course, so many cowboys companies and workers in this industry.

Is it possible to have an external or second temperature sensor with this controller? We also have an airbase

[@FullyAirconditioned]

You can plug in a remote sensor into the return air sensor port on the indoor pc board. Then that sensor can be placed somewhere in the house. You then set the controller to sense the temp from the return air temp sensor. If you wanted to switch from one to the other you would have to do it in settings in the controller. The other way would be to inset all a double pole double throw switch and wire two sensor into it and with the flick of the switch you would change sensing locations. You could install the daikin zone controller it has the ability to have two additional sensors fitted that can be selected from the controller. The problem with the zone controller is that it has a rubbish timer, doesn’t show actual temp, is difficult to set timer and doesn’t have half the stand feature of your current controller.

Do you also install the controller next to your zoning box? This may be a weird question but just needed to know. Also if I have installed my 2 controllers in by my wired thermostat, I still have 2 more left and the rest are wireless thermostat? Does it matter where I install the other 2 controllers?

[@FullyAirconditioned]

I don’t quite understand your questions, but with the controller if we were install a separate controller for zones (on off zones) we would normally install them next to each other. If the controller was a Myair zone controller that has wireless sensors, we would normally not install the daikin controller at all. With this this type of controller (Myair) the sensor location is set to the master wall controller (so Myair tablet) and the daikin controller becomes a slave controller (sensor not active). Then the Myair taps into the sensor input from the controller and tell what temp it is and manipulates the sensor input and controls the system like that. Dose that help ?

[@ryanroy5524]

@@FullyAirconditioned I think I do understand . I think all I needed to know was where would you place these controllers that’s all. I would assume you would Place them in a common area by the ac where it could sense the temp? Do these controllers go anywhere else?

You have a VRV system, the controller that has all the functions is the master controller, what it set to will only be available on the other units controllers. You can set a new master by holding down the mode button on the current master controller for 5 sec, all controllers should be flashing now, to select a new master you need to push the mode button on the controller that you would like to be the master.

The filter requires to be reset on the controller. Do you have a video or steps to restore the system as it is turning off after 10 mins as this message I believe is stopping it from functioning . Two Bulkhead in wall units connect to the compressor.

[@FullyAirconditioned]

Filter will not stop the system from operating, the filter is purely a timed function, it’s a reminder and it won’t stop The unit from operating. There is a reset for the filter, if you go into the menu you should find it there. The biggest reason the system could be turning on after 10 minutes is there could be a fault or you may have one of the energy efficiency setting set. So if you go into your main menu, check energy efficiency and just have a look at all the potential settings and make sure that they’re all set to off, that’s what I’ll be checking first.
