          Seems that the remote sensors would need to be able to open and close ducts to be able to control temps in the rooms where they are located in. But I did not see any mention of that in the ad. So how do they work?

          Answer This Question

          Answer posted seems to reveal a flaw in the design. To reach the desired temp in one room, all the other rooms are affected, i.e., to make one room cooler when other rooms are fine, the thermostat blows cold air longer into all rooms. Is that correct?

          By|Jul 13, 2024

            Hi LarryS, thank you for your question. These smart sensors are suitable for systems without dampers. When you adjust the temperature in one room, it will impact the temperature in the rest of your home. For example, if your basement is regularly 4 degrees cooler than your bedroom, it will continue to be slightly cooler as you adjust the temperature to meet your bedroom preferences. If the bedroom and the basement are both selected as priority rooms, the thermostat will average the temperature of those two rooms, and your basement will still be cooler than your bedroom. - Maria

                My existing thermostat only turns on the Heat or the AC. It does not switch from heat to AC automatically. Can this thermostat switch between the two based upon how cold or hot the rooms get?

                    This is an amazing unit - but you need to know how to set it up!
                    I seems many negative comments are because they do not know how to set it up. I bought one with 2 sensors - installed one in the family room, other in the master bedroom. I tried the motion detection at first to set priority rooms, but found when motion died down (say when you go to bed!) it doesn't detect motion and drops that sensor from priority. I then discovered the scheduling system - OMG! I first set up the Sleep period from 8:00 pm to 8:00 am, and picked the master bedroom sensor as the sensor to get readings from (called a priority sensor). I then enabled auto changeover in the thermostat (so it will change between heat and cool automatically) and set a temp range of 67 cool and 66 heat. If the bedroom is warmer than 67 when the Sleep cycle is running, it runs the AC until the bedroom cools down to 67. So, later in the night, if the temp drops below 66, it runs the heat until it get to 66 in the bedroom. The range for each period is totally settable. I set similar settings for the Home period and have it use the family room sensor for temp detection, and then set an Away period (using the actual thermostat for the temp readings) with a broader range - 62 to 74. You can also pick 2 or more sensors for a period and it will average the temp between them. If you want a period that acts like an overlap period, add another period, set it to run between the two periods you want the overlap, and pick the sensors you want to average out. And I have had no issues with sensor range. Another complaint I have seen is getting WiFi working. Even though it supports 5ghz, I had issues getting it communicating with my iPhone after connecting it to my 5ghz network. So I connected to my 2.4ghz network on both the thermostat and my iPhone, and it connected fine. I then reconnected my iPhone back to my 5ghz network and still works fine. BTW - 2.4ghz has a much better range and penetration than 5ghz. 5ghz is better for higher data throughput (streaming) but that is not needed for a thermostat. This thermostat system is beyond my expectations. I have recommended it to many people.

                      This unit had the features I wanted, namely the remote sensors for other rooms. The instructions were terrible, they tell you to take a picture of the existing wiring, don't tell you how to actually hook it up from scratch. I had to buy a 24 vac adapter to power this up and the instructions with that were better than for the thermostat. The daily programming is kind of clunky and the app makes it no easier. I just set it to a temperature and forgot about it. It does help average the temperatures in the rooms so that was my goal. The backlight is set to be super bright from the factory so the ideal thing is to turn the backlight way down or off so it isn't too bright.

                      This was such a drastic improvement over the nest, in ways I didn't even expect. I got this when the nest stopped engaging the reversing valve. The T9 system seems to be easier on the unit (startups are not as loud). It's very responsive to the temperature, keeping it very comfortable. Surprisingly, I have not seen a negative impact on my electricity bill.
