	RE: Mitsu PUHZ120Y 'Outdoor Temp 'error? By DavidB, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Hi David, I have no knowledge of your brand of HP. I have a Vaillant Aerotherm and the instal instructions make it very clear the outdoor temperature sensor must never be in direct sunlight. The sug...
	RE: Help needed with Samsung AE120RXYDEG By JamesPa, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	What do you mean by the tank pressure exactly, do you mean the pressure in the heating system or something else? I think this error could also occur if the filters are blocked. The dynamic pressure d...

	Interesting and sensible behaviour by the heat pump, prioritizing DHW as one would expect and ensuring no colder water flows through the DHW coil. Based on that I would say nothing to worry about, and...

	Exactly, the petrol pump icon, or left handed one armed bandit as I sometimes call it, indicates the compressor is running (and so active heating is taking place, unless it's in a defrost).
	Help needed with Samsung AE120RXYDEG - E111 error code By TomF, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Hi, I've got a recurring issue with my Samsung heat pump. It will work fine for a few weeks and then bring up an E111 error code. I check the pressure, release what air I can from the system, then res...
