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
or 3 wire), millivolt systems (with a 12-24 AC or DC
source), one or two stage cooling, and hybrid systems.
