Hello every one,
I recently got a Nest Learning Thermostat 3rd Gen on sale as I wanted the ability to switch on and off the Central Heating & Hot Water remotely.
I have a Glowworm Ultracom2 18sxi boiler (I believe its a system boiler?) with a seperate hot water tank to store hot water as well. It was controlled using a HORSTMANN CentaurPlus C27 programmer.
I was able to install the Nest thermostat & heat link and I am able to control the central heating using the "nest thermostat" & "nest APP" in my mobile. However I am able to switch ON the hot water only by manually pressing the center round button in the "nest heat link". The question I have is this: Is it possible to control the hot water as well using the nest thermostat?
The attached picture shows the wiring that I had before I installed the Nest thermostat.
Using the picture I basically did the following to connect to the Nest Heat Link:
N -> Nest N
L -> Nest L, Nest 2 (common) & Nest 5 (common)
3 -> Nest 6 (call for heat HW)
4 -> Nest 3 (call for heat CH)
Can anyone please help by sharing whether it is possible and if so how?
