Tråd: Low pressure switch (LP) alarm on IVT greenling HT plus E7

Go to 5.11 and change the setting to P3 kont. drift. This is just for testing and should not be kept that way. This way the pump will be on regardless if the compressor is running or not. Then do a Norwegian reset of the pump which is to kill the electricity to the whole system. Let it be off for at least 30secs and turn it back on. After restoring the electricity you can change the startup time to 20secs again.

Deltas and temps seem to be ok. (y) Cold side temps will vary based on mutch much the heat pump is extracting from the brine. The actual temp isn’t crucial but it is important that both sensors, brine in & out, is reporting the same temp when P3 isn’t running and that the delta isn’t too high. I checked my Greenline C7 HT+ yesterday and it takes under a minute for the bubbles to disappear. It is normal that you see them when the compressor starts. You can change the dark grey area in the picture but the most important thing is that you see all the info from the heat pump. You cannot confirm or see the alarms only see that it has triggered. There’s a port on a small logical board on the heat pump where it attaches via a serial port. https://online.husdata.se/h-docs/C00.pdf

Quite similiar gas temps in my logs as well. The reason for it dropping is when the compressor is resting.

GT6 reads around 66 degrees now.. the compressor has been running for some time now. I don't recall the compressor running that often b4 and I am worried it gets exhausted and lose it.. so honestly I wouldn't mind that heating runs sometimes on electricity (elpatron). I happen to have a fixed electricity price for the coming 2 years at low price (66 öre). But I will definitely now call the maintenance to look into the bubbles thing in the sightseeing glass. We are off on vacation next week for 1 week. What would you recommend to do while away? I have now the heat curve currently set to 1.8, it is giving us around 21-23 degrees inside. I was thinking to put it down to around 1..
