Apologies for another Nest question.
I`ve finished installing the Nest Heatlink to replace a Danfoss CP715. The rest of the system seems to be all Danfoss too (three way valve, tank thermostat on a Y type system).
Installed without any major issue - central heating working fine but don`t seem to be able to use the hot water boost or schedule hot water.
The heatlink is in the kitchen under the boiler and I can hear a click from possibly the heatlink when I call for hot water on the thermostat. Three way valve and boiler are upstairs in the airing cupboard.
I`ve attached the wiring diagrams for the installation. The brown wire (3 to 6) I had assumed that this was a switch. Is this the issue or is it another live?
I have the old thermostat to remove in the hall way but I`ve maxed out the temp and central heating working without any issue.
Any help greatly appreciated.
