SWING (HVAC cycling rate) This feature allows you to set the desired variance in temperature
between the 3M-50 setting and the room temperature required before the heating or cooling system
will turn on—from 0.5° to 2.0° F (.25° to 1° C). For example, if SWING is set to 2.0° F and the 3M-
50 is set to 70°F Target Temperature, the heat cycle will start when room temperature drops to 68°F.
Similarly, the cooling system will start when the room temperature increases to 72°F. The HVAC then
runs and will shut off at the Target Temperature.
To set SWING:
Touch SWING.
Touch the left/right arrows to set the SWING from 0.5° to 2.0°F.
The HVAC will run more frequently at .5°F and less at 2°F. Default is 1°F.
