Grouping cool or heat setting on multiple nest learning thermostats

[sk10504]

I am planning on getting 2 nest learning thermostats for our home.  Our home has 2 zones (1st floor & 2nd floor with thermostats on each floor) with single furnace and single ac.  The system uses a control (zone) panel controlling dampers to direct hot/cold air to the floor that is calling for heat/ac.

Is there a way to group the downstairs and upstairs nest learning thermostats so when i change the downstairs nest to cool setting, it automatically sets the upstairs nest to cool setting too?  otherwise, one could be on heat and the other on cool and they will be fighting one another to maintain temperature.

Hello sk10504,

I'm sorry for the late response and thanks for your interest in having 2 Nest Learning Thermostats.

Nest thermostats are not designed to communicate with each other, but they will automatically set your target temperatures. Once the system is on and both have the same target temperature, they will both turn on. Check this link for more information.

Please let us know if you have any other questions or concerns.

Thanks,

Mark

thanks for the info.  unfortunately, it nest thermometer will not work for me since i need upstairs and downstairs to be able to stay both on heat or both an a/c.  we have an open space plan and as a scenario if downstair nest calls for heat and and heat eventually rises upstairs, the temperature will exceed the second floor nest set temperature.  the second floor nest will then call for a/c to bring second floor temp down to the set point.  so, i'll end up heating and cooling the house back and forth.  i need smart thermostats where if i set one thermometer to heat, it will set the others to heat (or set one to ac and this will set the others to ac).

Hi there,

Thanks for getting back and letting us know about the situation.

I understand that you wanted to have them both set to your preferred mode. It appears that it's most likely the ventilation in your home that triggers your thermostat to activate your cooling or vice versa.

When they detect a sudden change in the temperature, at least a 2-3 degree difference, your thermostat will turn on your systems to maintain your target temperature. You might need to check the room ventilation and other options to compress the air or temperature inside the room to avoid the system's unexpected activation and deactivation.

Please let us know if you have any other questions or concerns.

Thanks,

Mark
