You would need to purchase one 3rd Generation Nest for each A/C unit you are controlling. Nest recently introduced the Nest Temperature Sensor which works in conjunction with the control unit, where you would place one of these sensors in the zone you want to set for optimal temperature. The logic is that typically the thermostat is not always placed in the room you want the most control. I have a home with three a/c units and added a Temperature Sensor to one bedroom since the thermostat was in the hallway. Works perfectly. Good luck.

Sorry, there was a problem. Please try again later.You can buy separate sensors for each zone. The sensors act as an extension of the main thermostat. You can change which sensor or thermostat you would like to use to monitor the homes temperature. Also, you can set a schedule if which sensor to monitor at each time of day. For instance, my master bedroom is upstairs and gets about 10° hotter than the rest of the house becauseit faces the sun in the afternoon. I usually use this sensor to maintain a reasonable temperature in that room.
Sorry, there was a problem. Please try again later.I’m not clear about what I’m looking at. Do you currently control each zone with a separate thermostat or do you have a single thermostat that allows control of each zone? That would be something Nest does not do. Nest offers sensors for individual zones so multiple temps can be monitored but my understanding is that it would heat to maintain a minimum temp in the zone of your choice. Other zones would be affected by the setting for the primary zone. My home has one Nest on the main level where it does a good job of maintaining a comfortable temp. My daylight basement level is always cold and I have only one furnace. I could get a remote sensor that told the Nest that my basement was at 62 and ask that space to be maintained at 68, but of necessity the main level would become warmer than desirable to accomplish that. The only real solution for the problem would be a second furnace or heat source controlled by a second thermostat for that area. If your zone system allows you to set 8 different zone temps from the same heat source it is beyond anything Nest is currently designed to control
Sorry, there was a problem. Please try again later.Assuming you have 8 furnaces and 8 air conditioners, you would need 8 Nests. I'm not sure if there is a maximum number of thermostats that can be used in one home. I have two zones with two furnaces and 2 air conditioners so have two Nests.
Sorry, there was a problem. Please try again later.Here is the answer from nest - https://nest.com/support/article/Does-Nest-work-with-zoned-systems I would recommend calling an HVAC person if you are not comfortable with the wiring aspect - also something new from Nest is the new Nest temperature sensor - ( T5000SF ) It comes in a 1 and 3 pack. I cannot vouch for its quality, as it is new, but Nest has been putting out a good product for sometime, and I would expect the same from this. I personally will be getting a couple of these, as my house has certain rooms that get significantly warmer during the summer due to sun direction, and this I hope to be a good answer to that problem.
