Nest Thermostat E Installation

[Branflake98]

Hi,

I plan on installing a Nest Thermostat E with Heat Link to my property however can’t seem to match up the wiring on the apps instructions.

The property was built last year and has air source heating installed, I have, in the cupboard some sort of tank with a Daikin control panel. I have then, in the hallway a Myson Thermostat for my heating.

I cannot match up the wiring on the nest app and not sure if it’s compatible or not.

I have attached my current set up including the wiring for the Myson.

The device will be provided from SSE Energy with the heat link I believe.

I most likely will need to terminate the live wires because it’s battery powered, what’s the best and easiest way to do this?

Black and grey to the Nest terminals.

The blue/brown L&N are 230V power for a proper mains powered thermostat or receiver, but as you have purchased a battery operated piece they are not required, but must be safely terminated and insulated.

Thanks for the response.
