Samsung Gen 6 Issues with outlet temp

EcoBaker · 2024-03-18T20:58:07Z

I had my system working quite well, a cop of around 3.8, and I had a plan about how to improve it with a few new radiators. I was controlling the system with a Hive, that my installer wired in for me. I set the Hive to about 28 degrees, it would fire up the compressor I left it like this 24/7 I would adjust the outlet temp to get the room temps I wanted, with no weather compensation. Rather manual I know, but I wanted to get a feel for what flow temps worked well given the outside temp. Its a simple set up, two bed terrace house, one open loop heating zone, all radiator valves full open. However I wanted to try running the system without the Hive, using the standard Samsung wired controller, and setting up weather comp, so I disconnected the Hive. I'd set the system to run based on the water outlet temp, which I had set at 30, which would have been about right for today. But without the hive the compressor wont stay on. What happens is the compressor turns on for maybe 3 mintues, water outlet shoots up to 38 to 40ish, the compressor turns off. The water outlet temp very slowly drops until below 33, then fires up again for a few minutes. Any ideas on what is wrong?
