Multiple Nest stats to taco sr503

Dank

What was the resolution to JayToomey's question in this thread?

 

https://www.googlenestcommunity.com/t5/Nest-Thermostats/Wiring-nest-to-a-TACO-SR-503-zone-board/m-p/...

I have the same question. I am using a nest power connector and successfully connected one thermostat/zone to the COM terminal, but I'm wondering how to go about connecting another Nest to a different zone.

You can connect the other zones to the COM terminal on the Taco. How many zones total? You might not fit all the wires into the screw terminal so just use a pigtail which is one wire into the screw and then wire nut the rest to the single COM wire.

I did wake up to a notification that one of the nests had insufficient power. It was a bit peculiar, as this was the one that had been working prior to the pigtail

Hi there,

 

Uh oh! Thanks for letting me know about this. Please ensure that the thermostat is up-to-date and try restarting it to be sure by going to the settings and restarting. To be sure, are all your thermostats the same versions? Could you please gather the power and wiring info on its settings under equipment?

 

I'll look forward to your response.

Mark

Haven't had any issues since that first day, and all thermostats show power connectors detected, so I think good!
