Thanks Craig, now lower the LWT setting to 30C and see what happens to how the system operates.
Right, finished timing. Now back to 8 mins on 20 seconds off again.
Flow temp 28.1 set to 30
Indoor 22.1Â
Outdoor 6.5
Room temp 19

Hi Craig,
I'm afraid that I have run out of suggestions.
There appears to be something fundamentally wrong with your heat pump, and/or how the system has been installed. The only thing that I can see that appears to be incorrect is the Teva_out temperature reading of -50C, which could possibly be due to a faulty or disconnected temperature sensor.
I would suggest that you e-mail Samsung Technical Help and ask them why your system may be operating as it is doing.
In the meantime set your system back onto WC mode and adjust for the required indoor temperature.
Â
Okay, many thanks for all of your help. I'll update if I find anything from Samsung. Thanks again. Much appreciated.Â
Interestingly, when I put the settings back to WC I get error E121. Upon looking this up in the manual it saysÂ
"Short-or open- circuit error of the room temperature sensor of the zone 1 indoor unit (detected only when the room thermostat is used) Error source - Hydro unit.Â
Posted by: @hughfPosted by: @mike-hAm I right in thinking that Craig's system (from Joule) does not have a buffer tank? I'm still trying to get my head round the mandatory buffer tank for Samsung ASHP question.
Â
It doesn't have a buffer, no...
Which set of instructions say that the samsung needs a buffer?
Â
@hughf Please see the topic about Samsung install and buffer tank
https://renewableheatinghub.co.uk/forums/postid/11342
Freedom Heat Pumps claims a buffer tank is required to be within the Samsung warranty, even though the manual implies otherwise and Joule make a pre-plumbed cylinder without a buffer tank.
Â
@mike-h Ah yes, good old freedom. I’d trust the instructions from midsummer wholesale personally. I know that GH was always getting 911 errors (low flow) on his early installs, so they probably mandated a buffer to deal with that issue, allowing the primary pump to run at full speed to charge the buffer.
