Operation Guide 3M-50
To turn your 3M-50 ON, press the MODE button on the right side.
This cycles the 3M-50 through HEAT, COOL, AUTO and OFF modes.
The 3M-50 programmable communicating
thermostat operates via a high-quality, easy-to-
use touch screen. To program or adjust your 3M-
50, 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.
