Has the system been told to refer to EXT RT ( this can be found in installer settings, System layout, Standard, Control method ) assuming your using 3rd party thermostats and not the daikin controller as stat. if you are using the daikin controller there is frost protection setting via the stat?
Thats the latest question from daikin, must check tonight when i get home.
so it happened again at 11:30last night, l have attached pics of what was running and temps. Have other pics of other settings
but not sure if relevant.
anyway ext rt was ok. Happened again this morning at 6am, only noticed which proves my point no call for heat, thermostat main a is off when this is happening and thats on when stat calling. V strange noise coming from pump this morning so def a physical issue rather then a setting. Was onto daikin and hoping to get engineer out and maybe replacement unit. Major buzzing noise coming from somewhere.
Just last update, turns out a small number alterma2 hps left factory with room frost protection enabled when i should be disabled,enabled on older monobloc hp. I was guided into installer settings and overview settings until i got to code 2-06, this had 1 beside indicating it was enabled, disabled it and appears the issue is sorted. This was probably casusing high energy usage all winter i hope. Thanks for all input here aswell, even daikin fella said you know alot about the heat pumps as was able to answer all his questions and rule stuff out.
Out of interest, does anybody know if daikin altherma 2 have sd cards like the altherma3? Just talking to guy at work who has the newer model and was asking me do i have sd card, seems to be usb port on front of the altherma 2 models but nor sure4 what for.
We have a Daikin EDLA08E2V3 Altherma 3 A and that came with a ‘Network Card’ ready to connect to our network and there is a USB socket just next to it on the MMI. My installer told me that ‘They don’t normally come with a network Card’ however, I’m not sure of this as it is firmly embedded in their manual and in the sales literature as well. My istallers had prepared the base area with three ‘sleepers’ for the feet to rest on - only to find when they came to unpack it that this model now only has two feet! Regards, Toodles.

Oh yes!, Sorry, forgot to say: The USB socket allows for a thumb drive to be plugged in and load pre-programmed configuration for the control and / or to save a copy of the configuration. Regards, Toodles.

Does it link to phone app to show usage etc. For my altherma2 i presume cant link to app as no sd card?
Yes, the card enables the MMI to communicate with iPadOS. And iPhoneOS in my case but I think Android is also possible. I can see ‘consumption’ and I think the granularity of their barchart is pretty rudimentary; nothing, 1 kW or 2 kW which I think is better then nothing but not by much! Though I have installed the app and linked it to the Daikin 7 or 8 times, it is still very poor and likes to tell me that it has found other units to add. When I allow it to look and install these new units, it just sits with a revolving graphic - the cows come home and the graphic is still revolving! The app indicates external temperature and there is a tab for service but there isn’t very much else so as apps go - it leaves a lot to be desired in my opinion. Regards, Toodles.

@toodles cheers man. So i shouldn't mind too much the older altherma 2 model cant do this. Have external kwh meter and can see produced energy on unit itself anyway.
@newhouse87I was somewhat underwhelmed at the usefulness of the Onecta app; I was expecting that the options on the tabs would enable me to see the same data (consumption and generation for a start) as seen on the MMI. Regards, Toodles.

anybody with a daikin, do ye know if BUH is enabled and runs during space heating when unit is in defrost mode. So far in December mine has run for 4 hours to aid space hating. Very costly im presuming and maybe unnecessary. Its needed for legionella cycle and last couple of degrees for dhw schedule i think but i dont want it for space heating.
