## Description

Product Description Help save energy and money with the Bosch Alexa and Google Home Connected Control Wi-Fi Thermostat. Easily control your home temperature with the sound of your voice as you communicate with the Alexa smart device. The full color 5-inch display thermostat touchscreen automatically turns on and off while you're away from home. Both comfort setting and intuitive scheduling makes it easy for you to choose a temperature for different times of the day without having to worry about your house being to hot or cool while not being there. Easily connect to Wi-Fi and view outside temperature to determine your in-home temperature throughout the day. The touch screen main menu features, date, time, temperature control, humidity, fan operations and general mode. You are able to access the main screen and set up thermostat from any smart phone or tablet. The Bosch Thermostat is compatible with any 24 VAC HVAC equipment on the market or any humidifier or dehumidifier. A C-wire (common wire) is required to power the unit. The C-wire is used to provide power to the thermostat and is available on most HVAC systems today that have three or more wires. Third party aftermarket products exist for adding powering options in instances where a C-wire does not exist. Includes a 5-year manufacturer . Product Enhancements for Commercial Use: Humidifier Algorithm Update allows the thermostat to control both evaporative and steam type external humidifier accessories. Dehumidifier Algorithm update includes Hot Gas Reheat compatibility that allows the thermostat to meet the humidity set point when connected to products equipped with a Hot Gas Reheat coil, such as a Bosch Water Source Heat Pump. This feature also allows the thermostat to meet the humidity set point through passive dehumidification when using Bosch Water Source Heat Pumps equipped with an ECM Motor. The new Cool to Dehumidify feature allows the thermostat to meet the humidity set point while in cooling operation when connected to an external dehumidifier accessory. Both configurations allow the thermostat to function as a humidistat to meet the humidity set point. Manufacturer Contact Information 800-283-3787

Review: Power or No Power??? - I read quite a few reviews, and in most cases customers were replacing their existing non-smart thermostats with this wifi enabled smart BCC100 unit. Some reviews will scare you that you need a power source for this. Well yes, but do not worry... My house was built in 1993 yes I repeat 1993 and when I disconnected all the wires of my existing very old thermostat that had only 4 - Green / White / Red / Yellow wires I was a bit disappointed. But all these copper leads came out from a sheathed grey cable that also had two other unstripped (unexposed copper leads) - a blue and a black. BINGO... that was the key. Yes this new BCC100 will USE all 6 leads. So here is the connectivty: Red goes into a RH and RC already jumped (connected with a U on the BCC100 - you can connect into either RH or RC because they are already connected to each other!!!). Yellow goes in to the Y marked connector (Right side of the array) Blue (previously unused) goes into O/B marked connector (Left side of the array) Green goes into the G marked connector (Left side of the array) White goes into the W marked connector (Right side of the array) Red goes into the RC (RC and RH are already connected by a jumper clip) - right side of the array - RC is for Cool and RH is for Heat. What remains? The Black (previously unused lead). This goes into the top right array marked C. This is actually the POWER cable without which the unit will not work. Now one more feature: before you put this on the wall, you can setup the entie system. How? Look on the back of the unit. There is a connector similar to the one you use for yor android phone charger. If you have any such devices, take that lead and connect it and the unit will come on. You can perform the entire initial setup, schedule for heat and cool times and slots, calendar day-date, wifi, registration of your device etc, all the features without even connecting to the A/C-Heat unit. Now your unit is fully programmed and ready to be connected. Snap in to the wall plate after making connections as described above - JUST MAKE SURE THE AC / HEAT unit is unpowered. Once the unit snaps in the wall plate, power up the AC / Heat unit and you will see the BOSCH logo and you are all set. I had already downloaded the app and as soon as my unit got registered I was able to control it from my iphone. Extremely easy and very smart!!! Both units Home Upstairs and Home Downstairs registered and fully functional... You may get a few errors while registering the unit but just ignore them and retry (mine worked on the third try) because it will register without issues. I give 5 stars to this product!!!
Review: Continuous and documented software problems for all - I have owned this thermostat for one year and four months. I do NOT recommend this thermostat and below is my full review and the reasons why this deserves a one-star rating. A little background. I need a thermostat with two requirements: Set my schedule by time of day, and connect through my phone to make temporary adjustments. I live in an area with time of use electricity rates, so I do not need a learning thermostat -- I know when to turn it on and off. I also wanted the ability to connect through my phone to verify the current temperature and if we have a longer than expected day away from the house, we can temporarily adjust the temperature. Looks: This thermostat looks nice hanging on the wall, has a large colorful screen, and has a white bezel. User interface: The interface and menu layout are well thought out and easy to navigate. The hold and temporary function are not as intuitive as they could be, but ok once you get used to it. The advanced functions require an access code in the manual, so each time I want to check them I have to find the manual. The schedule setup is a little clunky, but works once you work through it. Technical Support: As you will read below, I have made several calls to tech support. Each time they were helpful, kind, and informative – but usually unable to solve my issues. The reason I cannot recommend this thermostat: The Software: The problems with this have been ongoing since day one -- if it’s not one thing it’s another. For the first six months the device would randomly not connect to the thermostat or allow me to make temperature changes from the app. Sometimes it would respond, but not allow us to release the temporary temperature hold. I could fix it by pressing the little reset button on the actual unit – little use when I am 50 miles away from home. Approximately 3 months ago Bosch had a major software update for the thermostat and phone. Everything worked great for 1 month, but one day the unit would not connect to my home wifi. I contacted tech support and they were having an issue since the update and to try again in a couple days. Why my issue started a month after the update, nobody knows. It took about a week, but then it magically started connecting again. It worked for about a month and then the clock started displaying the wrong time. I would try to set it manually, but that caused it to set to a different time entirely – truly bizarre. This is crucial to my time of use electric plan, if it has the wrong time and turns on my AC unit during my peak electric rates only one time during the month, it would cost me enough to pay for the thermostat. The time issue seemed to resolve itself after about 2 weeks. The latest issue that prompted this review is last week is my app now says I do not have a supported device and I need to sync it with my app. I follow the setup procedure and it gives an error, cannot sync. I thought for sure they would have fixed it after a year and a half of owning it, but new problems continue to pop up. How can Bosch sell a product that just plain doesn’t work and continues to have problems? All I need out of my thermostat is set a schedule and connect remotely. After a year and half of continuous issues I’ve decided to write this review to let people know you will be constantly fighting this thing. Update February 2021: My last update. It has been relatively stable for the past few months, still wont connect about 25% of the time when we are away from the house. Bought a Nest E thermostat installed it and have not had a single issue or hiccup in 4 months. The Bosch went in the trash, I can't even bring myself to give it away.

The unit is now compatible with the Amazon Alexa device- all you have to do is follow the standard process on your Alexa mobile app to connect a new Smart Home device to enable the "Bosch Connected Control" skill. 

Thank you!
