Operation Guide CT80

The  CT80 programmable communicating  

thermostat operates via a high-quality, easy-to-use 

touch screen. To program or adjust your CT80, 

simply touch your finger firmly to the screen. The 

screen will automatically light up. The screen will 

respond differently to different types of touches, so 

you may want to experiment with your finger or a 

stylus (not included), to see what works best for you. 

The “beep” sound is heard when the CT80  senses 

a valid touch of the screen.
