Luke1 Posted September 2, 2021 Share Posted September 2, 2021 Recently I had a Nibe F2040 & SMO20 installed. Whilst the recent weather definitely doesn't require cooling I would like to know if the system I've got can be used for cooling in the future. After quite a lot of research I believe it can, however some parts of the manual talk about an accessory being required, however it doesn't state what that is?? If I were to enable cooling to be permitted in the Service menu, would I damage anything? Are all the pumps and valves etc. designed to run for cooling as well as heating? I am aware that I would need to be careful about the relative humidity / dew point to prevent condensation etc, Has anyone else enabled it on their Nibe units? 1 Link to comment Share on other sites More sharing options...
IanR Posted September 2, 2021 Share Posted September 2, 2021 I have the same unit, although with the SMO40. I have cooling enabled on mine and when I purchased in 2017 it required an additional cooling module to be able to cool. I was also told I needed the SMO40 controller.

matt_wood87 Posted Monday at 09:38 Share Posted Monday at 09:38 Hi @Luke1 did you ever manage to activate cooling, and did it require an extra accessory? I’ve got the same setup and keen to know more. Cheers Link to comment Share on other sites More sharing options...
Luke1 Posted Tuesday at 11:31 Author Share Posted Tuesday at 11:31 No extra accessories were required. I had to access the service menu by holding the back arrow for 7 seconds, and then selected permit cooling. Link to comment Share on other sites More sharing options...
