HVAC auto-switchover between cooling and heating using weather forecast
#1
Hi,

I have a thermopump that can be put in either cooling or heating mode - I want to design a logic that will automatically decide when to switch the modes and do it, instead of requiring manual switchover.

My idea is to use a script that runs daily at midnight - it will calculate the average temperature for the next 7 days, and use thresholds - if avg temp is less than X, then activate heating, if more than Y, then activate cooling.

One immediate question that comes to mind is - if it were the right thing to do, maybe the vendor of the heatpump would have provided such an 'auto' mode - but they didn't, so perhaps i'm missing something here and there's a reason not to do it.

Has anyone seen/implemented similar logic and can share from their experience of whether or not it 'works' for the comfort of the owner to not have to switch between the modes manually, or perhaps it will cause more harm than good somehow?
Thank you!
