multiple thermonstats to control single zone valve

[Ajj81]

Hi all,

hoping someone can help me out here.  I have a traditional Gas central heating system that is comprised of 2 zones (upstairs and downstairs).

The downstairs "zone" is actually an underfloor heating system that is controlled by 5 nest 3rd generation thermostats. 

The issue Im having is that only 1 of the thermostats actually controls the zone valve and calls the boiler for heat.  Meaning that if I want to heat just 1 room I have to actually heat 2.  Is there a way to get this so I can get another room to come on or will the 2 units just end up confusing each other?

thanks

youd need a Nest on every loop, or at least the loops you want to independently control. After that youd need to connect them to a wiring centre like the Heatmiser UH8 or similar. I have something similar to what you have, although its UFH downstairs and radiator upstairs. The UFH is 4 loops, but i have them connected to make 2x2, and i have  Nest attached to each. So i have 2 Nests for the UFH and 1 Nest for the rads upstairs.

Hi folks,

Thanks for chiming in, @Super_paulie.

@Ajj81, thanks for posting, and I'm sorry for the late response. If you have a traditional gas central heating system with multiple zones controlled by Nest Thermostats, it's possible to configure the system to heat individual rooms without activating the other zones.

Create a custom routine using the Alexa app or smart home platform to adjust temperature settings for specific durations. Set the desired temperature and duration, and reset the thermostat to Home/Away mode after the specified duration. Activate the routine using a voice command or schedule it for automatic running at specific times, like every night. By ensuring that each Nest Thermostat is correctly wired to its respective zone valve and taking any necessary compatibility considerations into account, you should be able to control each room independently without activating other zones unnecessarily. 

Let us know if that helps.

Best,

Zoe
