They were first on the list of approved Samsung heat pump installers and servicing in my area. Now they have stopped all heat pump installs, I can only assume their installs hit some problems. I’ve got some serious real oldies in the house, having to resort to supplemental oil radiators to stop them freezing to death.

Thank you, so it seems it isn’t the outdoor air temp sensor then. How difficult would it be for Samsung to actually produce a engineering diagram identifying each component!
So it’s a frost sensor, mine doesn’t touch the coil nor does the one in the photo that Sean sent you. Either they need to touch the coil or they don’t, it doesn’t seem to be a subjective requirement. I wonder if that’s why mine keeps going through phantom defrosts? Who to ask, my installer is useless, Samsung tech support is not existent. 2 steps forward, one step back, fecking heat pumps!
@papahuhu have you got any monitoring software on it?

@papahuhu I am attaching a photo of the sensor siting on the rear of my Daikin Altherma monobloc heat pump; it looks as though the sensor is some ~6-7 cm. from the fins to me. Regards, Toodles.
Toodles, heats his home with cold draughts and cooks food with magnets.
Thank you. So if that particular sensor is for frost, do you know where it is measuring outside air temp please? I can’t see it anywhere.
A homely optimiser is supposedly controlling the system. But, heat pump sits idle more than its on even with the heating settings on 24/7. Ramps up high then stops for an hour. Homely blames the installer, the installer says it’s fine, so I’ve gone to RECC as I’ve got oldies in the house and the bedrooms are at 12C whilst other rooms are tropical. Complicated by the installer reducing my emitter output in the rooms that are cold by about 50% when changing from a high temp system to a low temp system, don’t ask why!
@papahuhu Comparing our two arrangements of sensors, I suspect that the sensor you attached a photo of some postings back is of the sensor for the OAT similarly to my Daikin. Regards, Toodles.
@papahuhu If some rooms are warm then it sounds like either the radiators are not big enough in the bedrooms or they are being restricted by valves. Do they have TRVs or just lockshield valves

Been having some niggles with cycling and unnecessary defrosts on a newish install. Samsung Gen 6 R32 16kW 1P mono, not getting anywhere fast with installer. Image below is my outside air temp sensor which I would have thought would had a metal sleeve/ sheath covering a PT100 type RTD. What I find on mine is pliable black plastic tube surrounding some type of thinnish wire upto the point where the white cable tie sits, but for the final 2 inches it’s a completely empty plastic tube. I would have expected to see a metal sleeve/sheath sticking out the end. What’s in the picture is wrong, isn’t it? Thanks
This is perfectly normal. The outdoor temp sensor on my Gen 6 is identical.
Mine reads reasonably accurately, maybe slightly on the low side (~0.5C low).
The data can be read at the top of the home screen, and is used for WL (weather compensation) as well as defrost operation and pump anti-seizure cycles (below 5C).
Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
not beyond the basic Samsung controller and the homely modbus data which only the installer can view (and won’t share). I can sit there and watch the output, it’s nothing like you’d expect for a weather comp system. It “sniffs” at a very low output for about 10 mins, then stops for 5 mins, then launches into a 50C flow temp for 20 mins. By which time the reference room has reached setpoint, then stops completely for 30ish minutes whilst it drops below setpoint and starts the cycle again.
