How To Install CT100 Z-Wave Thermostat

Here is a video about installing it.


Our rating for 2GIG CT100 is great and gives it 4.0 stars out of 5. The reason we didn’t give it 5 stars is that it did’t provide usage reports and it must be programmed with a Z-wave controller. Despite this con, if you are a Z-Wave hub owner, it will reward you in a big way. It’s another useful and cool device for your automated home.
It is a great replacement thermostat for Z-Wave users. It supports Z-wave and it is a regular programmable model. If you want to buy a Z-Wave thermostat with incredibly affordable price, this one is a good choice.
