I have just moved into a new place and this is the first time I have had this type of set up so would like to get some clarification as to if I can use my 3rd Gen Nest stat.
I have a 3 phase supply with an air source heat pump heating a small pool, an electric Fusion Comet boiler (linked to a 2 channel Danfoss programmer) and an OSO water cylinder. An unvented system I believe?
I've tried to find an installer where I live (Jersey, Channel Islands) but no one is has installed one before and so it is proving difficult.
Does anyone know if it's possible to install it on a system/boiler like this and could point me in the right direction for any guidance for diagrams or instructions please?
Many thanks

It doesn't sound like what you want to do is compatible with any Nest thermostat.
The Nest thermostats are designed to only work with the 24vac control system that HVAC systems use.
Three phase power is not compatible.
