Wiring Nest 3rd Gen

[Scrow]

I have an old heating/hot water system that i am looking to upgrade to a Nest 3rd gen control

The system has a switchmaster SM805 and a Danfoss RX1 Reciever

Wondering how i can wire both of these to the nest unit

Any help would be appreciated

Hi there, thanks for reaching out! I suggest you call an installer to help you with the installation since there is high voltage. You can check the installation guide, but I can't tell you how you should install it since I don't have any knowledge about the system that you have at the moment.

Hi, I wanted to check in. Is there anything else I can perhaps try and assist with?
