Timeclock to Nest System

[Point2]

Happy Christmas/Holidays to all.

Want to replace the below timeclock with a Nest. System uses an oil boiler and an immersion heater for the water. Heating fully controlled by existing timeclock, no thermostats.

Current timeclock:

You do if it's single channel heating only

Just checking; you've got Nest in the title and the text, and a Hive wiring diagram...

Ah! Well spotted. Nest was an error. The Hive diagram is correct.

Thanks

I see on another forum that you are in Ireland, so you should really consider having this installed by a Registered Electrical Contractor (REC).
