The Nest learning thermostat is a green product that allows customers to have a programmable thermostat with the ability to memorise their living habits and come up with a suitable schedule for them.

And now available in the market is the T200577, which is the 2nd generation of this range. As compared to the 1st generation T100577, it was said to possess improved design and better software compatibility and functionality.

Therefore in line with the aim of this site, I have written up a Nest Learning Thermostat – 2nd generation T200577 product review to give a clearer picture on this green product.

Benefits of having a Nest T200577

2nd Generation Design

This Nest Learning Thermostat is more streamlined and is 20% thinner than the previous design. The new model is covered by a premium solid stainless steel ring that will reflect and allow the blending into surroundings perfectly.

The unsightly sensor grille on the bottom of the 1st generation thermostat has been replaced by a sleek and smooth sensor lens.    

Ease of Installation

Three out of four people can install the Nest T200577 by themselves in 30 minutes or less. This is comparable to the installation of a light fixture. Everything required for installation is in the box.

Increased Compatibility

As compared to the previous model, the T200577 is compatible with 95% of low voltage and cooling systems, which include 2nd stage cooling, 3rd stage heating, dual fuel, emergency heat, and whole-home dehumidifiers and dehumidifiers.

The unique and new “*” connector that comes with this model can accept any of these 4 wires (W3, E, HUM or DEHUM) ensures its compatibility with almost all heating and cooling systems in US and Canada.    

Improved and smarter software to fulfil consumers’ needs

The new 3.0 software installed in this thermostat contained improved features to the original Nest functions which I have summarised below.

System Match

Via this software function, the Nest Learning Thermostat utilises different algorithms and activates custom features that best suits your system. This will ensure smoother control and also make your entire heating and cooling work better. The features that will be activated depending on your inherent system are: True Radiant, Heat Pump Balance, Early-On or Filter Reminders.

True Radiant

This Nest exclusive feature will be automatically activated if one already has an in-floor radiant or boiler-and-radiator system. These systems, though more efficient, take a long time to heat up and cool down. With this function, it will reduce temperature swings and starts heating early so you can get the temperature you want when you want it.

Heat Pump Balance

Another Nest exclusive feature that is catered for households with heat-pump and auxiliary (AUX) heating. With this function, you can choose how much expensive auxiliary heat to use based on your preferences for comfort or savings. This also prevents AUX heating from kick starting too early when the heat pump could have been sufficient in maintaining the temperature.  

*Note the Heat Pump Balance function will be activated in the Max Comfort setting if you have a heat pump with auxiliary heat.


This feature will ensure that you can get the temperature you want when you want via its pre-emptive capability of heating or cooling early to meet your scheduled temperatures.

*Note both Heat Pump Balance or True Radiant have Early-On technology built in.

Filter Reminders

Filters are very important parts for systems that blow air out of vents. Your bill can increase by 5% due to clogged filters. Unlike other similar functions in other thermostats that only alert you once yearly or monthly, the Nest’s Filter Reminders are calculated based on the amount of hours you’ve used heat or air-conditioning. This means they will only appear when it is required to change the filters.  

The Power of Nest Sense™

The below features in a Nest Learning Thermostat will also allow the personalisation of your heating/ or cooling schedule and subsequently commit it to memory. 

Enhanced Auto-Away

The new Auto-Away function can now activate itself as fast as within 30 minutes after you leave home. It is also smart enough to note if you are usually around at this period of time even there is no activity, it will wait longer before activating Auto-Away.  

Enhanced Auto-Schedule

The original auto-schedule function can remember the temperature you like and self-program itself to meet either your heating or cooling schedule. The enhanced Auto-Schedule allows Nest to use this function for your schedule that have both heating and cooling mode and can switch between either of these modes automatically.    

Energy History

This function allows you to keep track of your energy usage by showing you when your system was on and if the weather, Auto-Away or your adjustments affected your energy use most.


The Airwave automatically turns off the AC a few minutes early, but keeps the fan running. Therefore the AC runs less while maintaining the coolness of your household.  

The Leaf

Want to know if you are saving energy when you make any adjustments? The Nest Leaf icon will guide you by appearing when you turn Nest to a temperature that is energy efficient.


Auto-Tune will find ways to lower your energy bill while keeping you comfortable, and then automatically does them for you.

New Languages

French and Spanish language functions have been added to the Nest T200577.

Android tablet compatibility

The Nest Mobile app is now compatible with all Android tablets, including Nexus 7 and Kindle Fire. The improved Web and Mobile apps included more detailed info about how and where temperatures were set can now be found in “Energy History”, the upgrading of the “At a Glance” screen that allow you to lock Nest remotely and switch the apps between English, Spanish or French.

Remote Control Capability

The Nest Learning Thermostat can be connected to Wi-Fi and controlled from your smartphone, laptop or tablet.
