Daikin brc1c51/61

[Palkoper]

Hi there anyone have got service manual 4 remote controller Daikin brc1c51/61 cos one of mine customer is so fasy and need to change temperature range ... if is possible .


So the temperature range is from 18 - 24 degree ... ????
How to change it higher or lower please I think it must be somewhere in 10 or 50 secret menu when holding TEST button ...


Thank You for any advice how to fix it otherwise I will lose contract

is it set for controller sensor control- is it sized correctly?-is it working correctly?- what does ur customer expect??- oh and model number would be good as some codes dont apply

In some ways that was good - it meant I had to read a bunch and had a reasonable idea what I was doing by the time I actually worked it out. But it also meant I tried a few things that probably I didn't need to.

Anyway, this thread is looking to summarise some of the Daikin codes, and how you actually use them. We've been gradually renovating our house, as we did that we've insulated, double glazed, and sealed properly. The heating/cooling load in our house has dropped quite a bit as we go, so our Daikin ductet unit is now oversized for the house. The things I was trying to do were:
- set the fan to go on a lower fan speed - I didn't need so much air blowing
- set the fan to turn off when not heating/cooling, as the air blowing around was annoying
- set the unit to use the thermistor in the wall controller, as once the fan turns off, measuring temperature in the return air causes the unit to cycle more frequently than it should (the air in the ducts under the house cools much faster than the house itself, so with the fan off, the unit would cycle quite quickly)

Firstly, how to enter the Daikin service codes.
1. Press and hold the "test" button. The controller should show "10". From here you can enter the 10 and 20 series codes, in particular changing fan speed and setting to read the thermistor in the controller
2. Press and hold the "test" button again. The controller should show "40". From here you can enter the 40 series codes - in particular accessing the temperature readings
3. Press and hold the "test" button again. The controller should show "50" From here you can enter the 50 series codes - which are really supposed to be for Daikin service personnel only - they can break your unit (i.e. use at own risk)
4. Press and hold the test button again. The controller should show "60". From here you can enter the 60 series codes - of which I know nothing other than that they are still more likely to irreparably break your unit than 50 series codes.

To actually enter a code, from any of the 10, 40, 50 or 60:
- use the temperature up and down buttons to change the primary number - e.g. to select 41
- use the clock up button to select the secondary code - e.g. to select 01
- use the clock down button to set to a particular value - e.g. to set to 02
- press the set button (clock with a cross through it) to set the value
- press the test button to exit. The unit should reset - showing 88 on the controller (it doesn't do this for 50 series codes)

To give an example, to set code 22-2 to value 01 (often shown as 22-2-01 on this forum) you would:
- press and hold test button - controller shows 10
- use the temperature up and down buttons to select 22
- use the clock up button to select 2
- use the clock down button to set to 01
- press the clock with a cross through it
- press test
- controller shows 88, unit resets

The codes that I think I'm aware of (user beware and all that, but all these seem pretty safe)
10-2 temperature sensor selection (this may be factory setting, and you should use 20-2 instead)
.10-2-01 measure temperature from some combination of controller and return air
.10-2-02 measure temperature from return air
.10-2-03 measure from controller only - if your unit supports this setting (mine doesn't)
11-2 factory setting for fan speed, don't change this, use 21-2 / 22-3 instead
12-4 perhaps controls how much temperature change you need to shift the unit from heating to cooling and vice versa
12-4-01 default (not sure what the default is)
12-4-02 1 degree set point
12-4-03 2 degree set point
20-2
.20-2-01 measure temperature from some combination of controller and return air
.20-2-02 measure temperature from return air
.20-2-03 measure from controller only - if your unit supports this setting (mine doesn't)
21-2 allows you to cut inside fan when outside unit stops heating/cooling
.21-2-02 cuts fan on heating and cooling
23-2 fan speed.
.23-2-01 - LL
.23-2-02 - set fan speed - I think this lets you set from controller
41-1 report what the different temperature sensors are reading
.41-1-00 reports controller thermistor
.41-1-01 return air
.41-1-02 liquid line return temp (no idea what one of these is, guessing it's part of the external compressor)
.41-1-03 suction line thermistor temp (no idea what this is either)
50-0 one thread on here suggested it did what 50-4 does on my unit. Not sure if this is different on different units, or just wrong on the thread
50-4 seems to be fine tuning for 10-2
.50-4-01 if you've set 10-2-01, setting 50-4-01 reads temp from controller only, not combination with return air

Hope that helps someone do the things I did. And hopefully someone more knowledgeable than I will point out anything I got wrong in that summary.
