Q: QuestionDoes the 4th Generation thermostat need the included temp sensor to monitor inside temperature in the same room as the thermostat?
Asked by pdiddy.
- A:Answer Hi there, thank you for your inquiry. The new Google Nest Learning Thermostat (4th Gen) does not require a sensor to function properly. However, for optimal temperature control and comfort, we strongly recommend using a sensor. You may also place the Google Nest Temperature Sensor in a different room to monitor and control the temperature in that specific area.

Q: QuestionWhen you set a temperature, at what point does the thermostat turn on the AC/heat? For example, if I set the thermostat at 76 degrees. When does the AC come on? When the thermostat reaches 77 or 77.5 or 76.5?
Asked by Billmore.

- A:Answer Hey there. The Nest Learning Thermostat 4th generation typically activates the AC or heat when the ambient temperature deviates from the set point by a small margin. This margin is often around 0.5 degrees Fahrenheit. It's important to note that this can vary slightly depending on factors like the specific settings on your thermostat, the efficiency of your HVAC system, and environmental conditions.

Q: QuestionHi, my installer tells me I need a "wire extender common maker". Is this included in the package or do i need to get it separately (and where do I get it from)? Thanks in advance.

- A:Answer Hey there! We're glad you've chosen us to help keep your home comfortable, year-round. Usually, most homes don't need a C-wire for the Nest Learning Thermostat (4th Gen) to work. However, some systems require one for consistent power. If a C-wire doesn't work for you, the Nest Power Connector is a simple and affordable alternative! It's not included with the Thermostat, but you can buy one at the following link: https://store.google.com/product/nest_power_connector If you have any other questions, reach us at this link: https://support.google.com/googlenest/gethelp?hl=en
