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.
Statement of use: 100% Compatible with all popular
residential HVAC systems; 24VAC single, two, three stage
conventional heating systems (gas/oil/electric), heat pumps
(single and two stage compression) and 1,2, or 3 stage
auxiliary heat (electric or fossil), zoned forced air and
zoned hot water (2 or 3 wire), millivolt systems (with 24VAC
adapter), one or two stage cooling, and hybrid systems.
