A:AnswerYour best bet here is to download the Nest app first and you will find out if your current a/c unit will work with this thermostat. Don’t buy the thermostat just yet if the app doesn’t tells you to do it.

A:AnswerThe Nest E does not work with PTAC systems, however the Nest Learning Thermostat does work with PTAC systems as long it's a system pushing 24V through solid copper wires to the Nest. With that said, a Nest Pro would be needed in order to ensure the Nest is installed properly with this type of system.

A:AnswerYep, you can do exactly that. Once you set it up, you can tell Alexa to change the thermostat to a specific temperature. I will say that it can be a bit nitpicky in terms of how you phrase the request, but that is pretty normal for most Alexa integrations.
A:AnswerIf you have more than one thermostats, then match the number of thermostats you currently have. Some homes may have one cooling unit but two thermostats -one for each floor. So its basically matching number of thermostats and not cooling units.
