I have had this thermostat installed for several years without any issues. Now when I turn on the thermostat it will go into 2nd stage cooling if I turn it down several degrees. We never had 2 stage cooling before. Did google do an update or something to change this. Thanks

Hi @Kenni,

 

I understand your confusion about the recent change in your Nest thermostat's cooling behavior. It's definitely unusual for a software update to suddenly enable a non-existent feature like 2-stage cooling. Let's see if we can figure out what's going on.

Understanding the System:

  1. Nest Model: To get started, can you tell me the specific model of your Nest thermostat? Knowing the model (e.g., Nest Learning Thermostat 3rd generation) will help us determine its capabilities for multi-stage cooling.
  2. HVAC System Check: More importantly, does your HVAC system itself actually have two stages for cooling? Some systems only have single-stage cooling, and the Nest wouldn't be able to activate a non-existent 2nd stage. You might find this information in your HVAC system documentation, or by contacting your HVAC technician.

Examining Recent Events:

  1. Timeline: Can you pinpoint when you first noticed this change in behavior? Was it around a specific date or after receiving any software update notifications for the Nest thermostat?
  2. Schedule Adjustments: Have you made any recent adjustments to your Nest app's schedule or settings, particularly related to cooling settings or temperature thresholds? For example, did you significantly lower the target cooling temperature recently?

Troubleshooting Steps:

Review Nest App Settings:

  • Open the Nest app and navigate to your thermostat settings.
  • Look for options related to "System" or "Equipment" where you might find settings for cooling stages.
  • Ensure these settings accurately reflect your HVAC system's capabilities (single-stage or 2-stage cooling).

Investigate Nest App History:

  • Check the Nest app's history view for your thermostat.
  • Look for any recent events or changes that might have coincided with the start of the 2nd stage cooling behavior. This could indicate a setting adjustment or potential software update impact.

Additional Support:

  • If the above steps don't resolve the issue, contacting Nest Support would be the next step. They can access your specific account details and provide more tailored troubleshooting based on your system configuration. Here's a link to reach them: Nest Support

By gathering more information and trying these troubleshooting steps, we should be able to understand why your Nest thermostat is now using 2nd stage cooling and potentially adjust settings to achieve your desired behavior. If it turns out your HVAC system doesn't support 2-stage cooling, Nest Support can likely help you prevent the thermostat from attempting to activate a non-existent stage.

 

Regards,

Mario.
