OPERATING INSTRUCTIONS
Once you have installed the external sensor cable,
the DTR900 will monitor both inside (IN) and
outside (OUT) temperatures. This display
configuration—with IN and OUT temperatures
shown on the left and the TIME shown at right—
is the “normal” configuration, as shown in Fig. 1.
To switch the IN display at lower left to display the
current date (see Fig. 4), press the IN/DATE button.
Use the IN/DATE button to toggle the display on
the lower left between the inside temperature and
the date.
