INDOOR TEMPERATURE/RELATIVE HUMIDITY

The thermometer/hygrometer automatically displays the current indoor
temperature and relative humidity on the upper display.

Note:  If the indoor temperature rises above 104 degrees F/40 degrees C
       or falls below 23 degrees F/-5 degrees C, the upper display might
       blank out until the temperature returns to within the operating
       range.

OUTDOOR TEMPERATURE

The thermometer/hygrometer automatically displays MEM (memory) and the
current outdoor temperature on the lower display.

Note:  If the outdoor temperature rises above 158 degrees F/70 degrees C,
       the thermometer/hygrometer displays HHH on the lower display.  If
       the outdoor temperature fails below -58 degrees F/-50 degrees C,
       the thermometer/hygrometer displays LLL on the lower display.

COMFORT RANGE

When the indoor temperature is between 68 degrees F/20 degrees C and 77
degrees F/25 degrees C, and the indoor relative humidity is between 40%
and 70%, COM appears on the upper display.  This indicates the best
environment for your comfort.

HIGH/LOW RELATIVE HUMIDITY

When the indoor relative humidity rises above 70%, WET appears on the
upper display, indicating excess moisture in the air.

When the indoor relative humidity falls below 40%, DRY appears on the
upper display, indicating inadequate moisture in the air.

OUTDOOR TEMPERATURE MEMORY

The thermometer automatically stores the lowest and highest outdoor
temperatures it recorded since you last pressed RESET or replaced the
batteries.
