Hi Ian, I started with a Hive thermostat because I had that with my previous LPG setup. I wasn’t happy with it because it’s too fine-grained for the heat pump i.e. it stops heating when 0.1c over target and starts again when 0.1c under; my HP has a high start-up cost so I don’t want it starting a l…

[image] iantelescope: I currently use a simple Honeywell radio controlled relay switched “thermostat”. I am considering using a “smart” European 240 vac Thermostat. Hi Ian, Be careful what you wish for ‘smart’ doesn’t necessarily convert to intelligent when coupled with an ASHP. You could…

Hi Christian,Brian,William,Tim My “installer” has just E-mailed to say that " a new replacement “manager” has been appointed to replace Tony Dunn , the former “manager”, who was blamed , and fired, for the fiasco in installing my Samsung Heat Pump. The new “manager” is trying to get Samsung to “i…

Hi Brian, The alarming "instability " I have encountered with the Samsung could be reduced with the provision of a “Continuous” Thermostat control. A suitable control could be interfaced using the Samsung “Intesys” KNX to F3/F4 converter. F3/F4 is the Samsung RS485 control bus. Any Thermostat usi…

Hi Brian and Christian, Just discovered the price of an Intesys for the Samsung £2400 !!! The Zennio KNX Thermostat comes in at £480 … Sorry, ian

Ian, I’m glad your installer seems to be doing something. With regard to the F3/F4 thing I think that’s just adding another layer of complexity. If I had the same problems as you I would revert to pretty basic settings as they should have been done (but correctly!) for the new install. Christian…

At risk of being off-topic, I mostly Avoid thermostats because I run the house heating “normally Off”, “unless there are Renewables Available”, “except when it gets too cold”. The default heating plan is to go out for a walk, and the house quite often feels warm enough when returning to it. I avoi…

Hi Dan, Many thanks for your response. I totally agree with your comments about the unexpressed, hidden, motive of the Energy companies in trying to get the user to spend as much as possible on Energy. The Energy companies well know the importance of energy saving , but have an obvious motive to…

Very interesting thread. I don’t yet have an ASHP but I have been researching towards getting one and shared the concerns expressed here over whether common smart thermostats were suitable such as Tado, Nest, Drayton, etc… FYI - The Tado supports both ye olde call for heat control which would likel…

Hi John, Now, today, I am probably the last person on the planet to advise anyone to use an “installer”. My “installer” having been STRUCK OFF TWICE in the last six months. I do not know of the London situation for Heat Pump Installations, but would advise that you do not trust the guarantees pr…

I’d go to a clean sheet of paper; “what do I Really need?” because the answer which I got was Not to remove anything. The £5k government incentive to spend £10k more than you might need to, is a distraction. I only Added to house heating capabilities, and added to diversity of supply, with the air…
