I am trying to set “Weather Compensation”, but settings do not match those on YouTube demos. Upper temperature change not available and lower tremperature change always returns to -30C. See photo. What am I missing/ getting wrong here? [IMG_1337]

[image] AlgarveASHP: However if you select “View” there is a provision for adjustment of the lower temperature with horizontal arrows. View does not change any settings, but simply lets you slide along horizontally to see what the flow temperature will be at a given outdoor temperature. In y…

[image] AlgarveASHP: What am I missing/ getting wrong here? Have you long pressed the menu key?

From the Main Screen, I long press Menu and get ‘DHW’; ‘Home’; ‘Timer’; ‘Holiday’; ‘Initial’; and ‘Service’ I select ‘Home’ and get photo 1 and I select: ‘Compensation’ (Note that whichever I select the Compensation panel appears on the RHS) As I previously commented, I then have no practical adju…

Photo #1 looks like the display you get when you short-press the menu button. The 4th button is the one to edit the curve, yet the pencil symbol is missing. Does it do anything when you press it? [image] PS: from the manual… [image] The arrows at the bottom will change from white-on-black to bl…

Thank you very much Timbones. You were correct and although “my” long press brought up the second menu it was obviously not long enough to bring up the weather compensation adjustment on the subsequent screen. Now on the ‘Compensation Curve’ icon I have the ability to view AND to adjust. [IMG_134…

I don’t know the FTC 5, and maybe I misunderstand your question, but to me your photo is saying that at ambient = -15degC or below your target flow temp will be 50degC, at ambient temp = +35degc or above your target flow temp will be 25degC, and between -15 and +35degC your controller will interpola…

Hello Sarah and thanks for your contribution. I wasn’t particularly referring to a temperature of -30C, but just to the numerals to the right hand end of the graph. As I said later, my lowest temperature out here in the Algarve is not likely to reach -5C, so I am going to start with a lowest settin…

Depending on the heat loss of the property, size of the heat pump and output from emitters (radiators or underfloor) you might be able to get away with a lower flow when it’s cold, say 45C. Conversely, you may find the heat pump cycling more often with low flow temperatures in mild weather as the r…

Do you have Melcloud? Do you want to see stats from your heat pump in a better format? Send me a message and I’ll explain how I can help get your data out…

Hi Tim, Sorry I am involved in clearing a house for a friend who has moved back to UK. Very interested in what you have to say and yes, I have been using Melcloud although I am unsure of overlap on FTC5 settings. At the moment, I can’t see how to do private message from this Forum.
