Thermometer/Hygrometer

CURRENT 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 104.0 degrees F/40.0 degrees
       C or falls below 23.0 degrees F/-5.0 degrees C, the upper display
       might blank out.

CURRENT OUTDOOR TEMPERATURE

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

Note:  If the outdoor temperature rises above 158.0 degrees F/70.0 degrees
       C, the thermometer/hygrometer displays HHH on the lower displays.
       If the outdoor temperature falls below -58 degrees F/-50 degrees C,
       the thermometer/hygrometer displays LLL on the lower display.

COMFORT RANGE

When the indoor temperature is between 68.0 degrees F/20.0 degrees C
and 77.0 degrees F/25.0 degrees C, and the indoor relative humidity is
between 40% and 70%, COM automatically appears in the upper display.
This indicates the best environment for your comfort.

HIGH/LOW RELATIVE HUMIDITY

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

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

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

To return to the current outdoor temperature display, press MIN or MAX
until MIN or MAX disappears from the display.

RESETTING THE TEMPERATURE MEMORY

To clear the lowest recorded outdoor temperature, press MIN until MIN
appears, then press RESET.

To clear the highest recorded outdoor temperature, press MAX until
