What do I do with my existing CH HW settings?

[mikeramseyer]

I have moved into a brand new house.

A Nest 3 Learning was  already installed as well as a coventional CH HW megaflow system with a Solus controller.

It seems to me that one controller is overriding the other and I don't know which.

So it makes sense to use NEST to run the CH and HW but how should I set the existing CH HW controller?

Should I set the Solus controller to 'off' 'auto/timed' or 'constant/on'?

Hi mikeramseyer, 

Yikes! Let's sort this out. Are you located in North America or Europe? And could you send us a photo of your Nest Learning Thermostat and your CH HW megaflow system with a Solus controller so we can visually check on them?

I'll look forward to your response. 

Best,

Zoe
