When I change the temperature on the Nest it self it goes into 2nd stage cooling without a problem.</P><P>Model: 02A, Backplate-2.5</P><P>Software version: 4.2.8/3.1</P><P>SOFTWARE 5.9.4-5 (September 28)</P> Wed, 08 Jun 2022 01:08:00 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-app-won-t-turn-on-2nd-Stage-Cooling/m-p/177421#M36088 Ivan275 2022-06-08T01:08:00Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-app-won-t-turn-on-2nd-Stage-Cooling/m-p/195082#M39221 <P>Same. &nbsp;We use iOS, but my AC guy said “The system is only set up for one stage.
