Wiring 3rd gen nest learning thermostat heatlink

[ampav_is]

Hi,

I have a European 3rd gen Nest learning thermostat (T3029EX) and I need to replace one of my current thermostats and test it before I purchase more.

My heating and cooling system is:

• A Daikin heat pump / boiler (I believe an Altherma model) that controls the temperature of the water and sends it through the home system.
• Underfloor heating and cooling on all 34 floors. These are connected to a Legrand Smarther thermostat (link at the end). I'll keep them for now and will replace in the future. I believe even a Nest E should suffice here as the legrand ones are pretty simple too.
• Fan coil units on all 4 floors with 3 fan speeds. These are connected to a Hailin Breath thermostat which unfortunately don't have any integrations with other systems but just a crappy app. 

I can't figure out how to connect the current wiring to the Heatlink of the thermostat for both heating and cooling but also controlling the 3 fan speeds.

Important note:

My house is in Athens, Greece and I havd a very hard time finding electricians or skilled professionals that know how to install Nest here. Any advice where to find one is very welcomed. 🙂

Hi there, thanks for reaching out! The European version of the Nest Learning Thermostat or the Nest Thermostat E, doesn't support the cooling, only the US version does. Also if you have a heat pump which is reversible or hybrid, that is also not supported by the European version of the Nest.

Hi there, just checking in with you. Did you manage to check my colleague's last message?

Do you know if a US version will work in Greece with the system mentioned above?

Did you try the compatibility checker? Does it say it's compatible?
