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!!!
