How do i? Get daikin vrv iii discharge temp

[Aircon467]

Hi guys/girls

I see a lot of you are clued up on daikin vrv iii

This is a new install and i would like to know how to get the compressor discharge temp via the new style controller (brc1e52a7)

I only have 1 remote controller per system
I also have the itouch controller

Each system has 2no outdoor units, its a 3 pipe system.
Outdoor setup is remq10p8y1b & remq8p8y1b (both linked)

Any further info required to help me?

Thanks in advance

I haven't used one of these BRC1E since I was in Australia, but I remember that they give you a lot of details.

press and hold cancel button for 5 seconds then press and hold cancel button for 5 seconds again.

scroll down to outdoor display or outdoor sensors or something like that.

press the cancel button again to exit

Hope this helps

set the system in heating mode with setpoint 30 and as icemanpaj says hold the TEST button for 5 seconds then another 5 seconds. timer up to setting mode 41 temp up to read 00 return air 01 controller sensor 02 pipe sensor- that will give you discharge temp in heating mode should rise to 33 deg then the indoor fans will speed up- left in test can reach 50 deg

Not quite correct IM. That only applys to the older BRC1D.
The BRC1E has a Big text display and has words instead of the mode 41 we are used to.

Use PT chart to get your discharged temperature from your High-pressure reading.
Normally 47C to 50C around 400 to 420psig for R410A system regardless of brands.

Can you explain that further.

[JoeAT50A]

Either VRV or VRF, mostly are similar
Compressor discharged temperature around 85 to 100C
B::Condenser outlet temperature around 40 to 45C
Subcooling target range fall between 8 to 12C (let say 10C)
A::For R410A High pressure around 400psi (47C) to 420 psi (50C).
We called it condensing temperature to find out the subcool from "A" minus "B".
So that we can adjust the refrigerant easier.
Hope this help!

no, that will give you your condensing temp (saturated)

discharge temp is superheated.

[JoeAT50A]

That's why I am saying that Compressor discharged temperature around 85 to 100C.
Sorry for confusion. My apology, maybe I have not given enough proper explanation.

Aircon467, how is the system now? please update.

The compressor discharge line temp can only be measured using a touch probe (on each comp) or with a service checker.

Compressor discharge superheat = dischrge pipe temp - saturated condensing temp

You can only view indoor sensor values from the remote controller, in heating mode the indoor gas pipe sensor value will be considerably lower than the compressor discharge temp.

Hold down cancel button for 5 secs x 2
scroll down to sensor address display & enter
First 2 digits are indoor address - Second 2 digits are sensor address
00 = R/Con
01 = Return air
02 = Liquid/coil
03 = Gas pipe
