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

[@Gasp665]

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.

[@Shaya-lz8lk]

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.

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.

Hi, if I wanted a specific room temperature to be monitored which setting would this be? For example the main bedroom I put it on 25 degrees but it goes to 20 degrees when aircon is on, I think this is because the main living room is the temperature recognition but we arnt cooling it therefore thinks he needs to pump it colder? Tips please

[@FullyAirconditioned]

Mabe invest in a smart zoning system like the "MyAir zoning system", this can be retrofitted to a Daikin system, it will give you temp control in all zones and the ability to select what sensor is active. You can just leave in automatic and it will set the room with the biggest temp difference from set point as the master to cool that room faster, if the other rooms reach set point the zone will automatically close off stopping the supply of cool air to that room. It's your best bet to give your Daikin more control, you will also have wifi as standard with the myair.

[@HugDeeznueces]

Loving Arlo! Good looking pup. Craig, I have a Daikin mini split as a second system in my home to cool the second floor which has all the bedrooms. My indoor unit is a FMDQ24RVJU and the outdoor unit is a RXL24UMVJUA. the. O troller is the Daikin OnePlus. I am in the USA and these systems are fairly new into this American market (from what I am aware of…) I am having a problem with overcooling with this system. Are the field setting tje same as what you have explained here? I am having a hard time finding a document that explain what each setting is. The same for what each mode is. I was wondering g if you could provide a link to where I could go find such document. The installer has not been successful on getting this unit to work properly. It is his first Daikin install 😢 Thanks for your video as you explained some of the settings. Sub’d and I hope to hear from you. Cheers!

[@JasonAshworth-e9u]

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.

[@JasonAshworth-e9u]

@@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!

I was wondering if I could ask a question about efficient use of this unit over the winter? Currently I leave it on all day/ night set between 18 and 22 degrees Celsius. 18 when I leave the house and in between 20-22 when I get home. 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.

[@victoriaweingartner6376]

@@FullyAirconditioned rather than turning it off, what settings would you have during the winter? Would you switch from fan to heating when you are not home? or would you put heating on all day and lower the fan speed when out? - Presuming you can't do this in the scheduling?

[@FullyAirconditioned]

@@victoriaweingartner6376 Hi Victoria, Well we have our Daikin set to turn on to 22 degrees at 5.30am , turn down to 16 deg c at 9.00am, (make shore it set to heat because if it’s set to auto it will cool the house to 16 😬). 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. That’s how we run ours, if someone is home they can over ride the settings, but next time it passes through a schedule it will change to the set schedule.

[@Yourskinnursemaddy]

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. Thanks Craig

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.

[@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

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.

You should be able to connect a 2nd controller, one will be the master and one will be a slave controller. The 2nd controller can be a wireless remote controller. The wireless remote has a receiver and the actual wireless remote. The receiver is wired back to the indoor unit just like the wall controller and is surface mounted on the plasterboard wall or ceiling. The remote is IR, and only work “line of sight” to the receiver, like a tv remote, it doesn’t work if it’s not pointed at the tv’s receiver. Think it’s a BRC1E62.

Also, is the BRC1E63 still the latest model? If not, do the latest controllers have any new features compared to this one?

whats it doing

[@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.

[@Greynomad1000]

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.

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.

[@kevcorduroy5388]

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)

[@samuelguaranteed5163]

Is there a setting for the electric auxiliary heat ?

[@FullyAirconditioned]

No, when the booster heater card is plugged into the indoor unit, it operates automatically. Booster heater will come on then the indoor coil temp is below 38 degrees and the return. Air temp is 2k below the set point. After the system has been operating in heating the indoor fan run on for 60 sec after compressor has cycled off to cool the elements.

Hi there, I keep on getting a message on the screen about filter needing to be cleaned. I clean it but message is still there. Can I get rid of the message? Is there a way? Apart from that aircon works fine.

[@FullyAirconditioned]

The air-conditioner doesn’t know that you’ve cleaned the filter. The filter sign is just a timed reminder that comes up after certain period of time on this controller. To clear it you’ve got to push and hold the clear button, that resets the timer and then after 1250 hours will come up again as a reminder. It doesn’t actually know that you’ve cleaned the filter or if the filter dirty.

[@AbsolutelyEverybody1]

@FullyAirconditioned ok so basically when that "time to clean filter" or similar appears...go and clean filter and then reset the filter timer - then that message should disappear? So really the filter should only be cleaned when the clean filter message appears?

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.

[@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.

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

You can change it and see what one works best for you.

If the Daikin system comes up with U0 in out experience its usually correct in that the refrigerant is low and you have a leak. You need to leak test, find and repair the leak, pull a vacuum below 500 microns and hold for 30min to prove the leak has been repaired. Then charge by weight the correct refrigerant charge into the system, you can not top up it will cause more problems. Repair it correctly the 1st time and it wont give you problems.
