Operation Guide CT50
To turn your CT50 ON, press the MODE button on the right side. This
cycles the CT50 through HEAT, COOL, AUTO and OFF modes.
The CT50 programmable communicating
thermostat operates via a high-quality, easy-
to-use touch screen. To program or adjust your
CT50, simply touch your nger rmly to the
screen. The screen will automatically light up and
you will hear a “beep.” The screen will respond
differently to different types of touches, so you
may want to experiment by touching it different
ways, nger, ngernail, etc. Do not use a sharp or
metallic device; it will scratch the screen.
