Digital Roomstat

Johntheo5 · 14 Oct 2023

I installed one of these (FantiniCosmi) about a year ago, its a very simple stat with only a adjustable differential of 0.3C to 2C. I have it set to 0.3C differential. I have noticed though that it switches in at its SP-0.15C and switches off at its SP+0.15, yet I have to increase the SP by 0.3C to get it to switch on if I turn it up immediately after it switches off which one would think is correct for a roomstat in heating mode, ie switch on at SP-0.3C and off at its SP. Has anyone noticed this behaviour?.
