It is my first dive into the world of programmable thermostats and before buying a HestiaPi, I’d like to make sure it can replace a RAMSES 722 S. Given that the latter is a basic thermostat (hot water is on demand and there is no cooling), I’m thinking of getting the HestiaPi Touch.
Thanks for any help,
Hello Christophe and welcome to the club
I looked at your link and the schematic. As long as you use only the contacts 2,3,4 and 5 in your wiring you are good to go. Please check the inside of your thermostat or simply send us a photo.
