Nest Thermostat

[MarkH84]

I’m looking to get a Nest thermostat, my house has a gas boiler with a hot water tank on the top floor and heats two zones, one for most of the house and the other for the lounge. There is currently one controller/programmer downstairs which controls the main house and another in the lounge to control there. Each controls an independent valve on the tank allow hot water to follow through its respective area when turned on. 
im aware I’ll need two thermostats, one to control each area, my question is do you need two heat links installed or can both thermostats run off of one heat link?

thanks

You can configure the heat links to control the other thermostat in the google home app.

Thanks do you mean heat link or Links? As my question is would I need two heat links or can I get away with one heat to run two thermostats? Thanks again

This has been asked dozens of times on here.

No is the answer, you cannot run 2 displays and one Heat Link!
