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 finger firmly 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, finger,
fingernail, etc. Do not use a sharp or metallic
device; it will scratch the screen.
Statement of use: 100% Compatible with all popular
residential HVAC systems; 24VAC single, two stage
conventional heating systems (gas/oil/electric), heat
pumps, single stage or with auxiliary heat (electric
or fossil), zoned forced air and zoned hot water (2

source), one or two stage cooling, and hybrid systems.

Questions and answers
my battery symbol will not go away after i replaced the batteries with new ones.
The battery symbol may not disappear on the 3M device with part number 50 after replacing the batteries because, even if voltage is normal, the battery may not provide enough current. This can cause the device to still detect a low battery condition.
