Thanks for your reply. I have a slight water leak (outdoors so not too worried)- so phoned the installer to get it sorted - and asked about any changes to get it to cool - he obviously only knows the settings he was told to make and said "that would be good if it could cool". I have a Samsung Eco - 8Kw. I have the manuals - which are good bedtime reading. The only settings to make it work in cold mode seem to be to change it from "heat only" to "heat and cold". The "waterlaw" has two parts - one for heating and the other for cooling. For cooling the only figures that seem relevant are the temperature the waterlaw takes over with it's lowest output (the minimum outdoor temperature) and the higher value when the pump will be on full output. The lower, when the waterlaw provides the lowest output has a minimum of 25C, which is why I do wonder if it will not start working under that outdoor temperature. It is possible to alter some other variables such as the pump's out temperature but unless it works at all that is immaterial. If it does work then perhaps sometime I would change the radiator to one that has a fan - I wonder if they also have the water in at the top and out at the bottom as that would force the cold water to spread across the radiator to some extent. I am considering setting the temporary thermostat I have fitted to demand cooling and holding a hot water bottle on the outdoor thermistor to fool it into thinking the outdoor temperature is higher and see what happens. I will come back to update on the progress. I hope I have not messed up the original post, but it seemed appropriate to confine cooling issues to this thread until more people are asking bout cooling.

Great - the reason I joined! I have a Samsung AW heat pump, fitted earlier this year (by chance on the coldest days of the winter just to remind us what a cold house is like). It was fitted totally free - including solar panels as my wife is disabled, so I had to accept what I got - which included basic settings. It is radiator only. I have need for cooling just one or perhaps 2 rooms as my wife can't tolerate heat. I have studied the Samsung user manual and find little to help work out how to turn it cold. I fitted a thermostat which surprisingly made it display cooling where it only showed heating before. I had to change one setting to tell it I wanted heat and cold. If I turn the thermostat to demand cooling the water circulates but the heat pump does not start. I am thinking the device thinks I don't need it on until the outdoor temperature is hot enough for whatever pre-set notion Samsung have. The Water Law (climate control) just has temperatures that set the lower and higher limits of it's water law algorithm - but surely it can work outside these. In heating mode you set similar parameters but if the outside temperature falls below or above these it will still work. I changed the lower setting to it's minimum 25 degrees, today has been 21 C so it may be I have to wait for the anticipated hot spell. I would really appreciate any help.

Hi, I'm an old codger of 75 who really has run to nearly the end of my projects (I'd like to keep going but my wife says I have passed my sell by date). Of course there are things to do and some technical help for the newest stuff. In the past I have converted a flint barn (I did use a builder for the floor and steelwork), built extensions without help - including the drawings etc, renovated neglected buildings (largest was a 12 bed hotel in Austria - by the time I'd fitted en-suites I felt pretty good at doing them - and installed a second hand heating system that ran in wood chips, I collected it in four stages as it was a pile of stuff in a barn. Before it was naughty I have rewired houses, fitted gas central heating and plastic windows. In the last 23 years I have lived in Austria twice, France, Isle of Mann and several places in England. Some time I will be moving again to be free of a large garden - so that may give me an excuse for a final swan song of house doing up. After a flair-up of my emphysema, then with various arthritic joints I have swapped the sledge hammer for repairing clocks (but not for long I hope).
