Temperat ure Trend of p ast 12 hours
Dynamic BAR graph trend of indoor tem perature for the past 12 hours
This unit is equipped with a dynamic te mperature trend feature for the past 12 hours. It moves from right to
left to indicate the temperature changes by comparing the p ast hour temperature to the current
temperature. Maximum range is up to +/- 5.4 °F (+/- 3 °C) at past 1, 2, 3 , 6 and 12 hours.
How to read tem perature trend
1. Horizontal scale of 0, -1, -2, -3. -6 & -12 mean current time (0), p ast 1, 2, 3, 6 & 12 hour respectively.
2. Vertical Scale of +/- 5.4, 3.6, 1.8, 0 degree °F (+/- 3, 2, 1, 0 degree ° C) mean temperature changes
compared to current temperature.
3. The unit will detect temperature trends automatica lly and needs at least one hour before it can start
displaying the temperature changes. It’s recommen ded to begin reading the trend after the unit is on and
working for 12 hours or longer.
4. As time passes, the display will show the temperature rising or falling trend by turning the bars ON /OFF
automatically based on past 12 hour temperature readings.
Note: 1.) One lighting bar scale = 1.8 °F (1°C).
2.) If the temperature c hange exceeds +/-3°C, a full BAR grap h or 1 BAR graph will be displayed.
3.) The temperatur e trend is calculated by changes in the temperature and is indi cative only. The
calculation can be affected by many things including where the unit is placed.
4.) The unit is for indo or use only. There are no guarantees for the accuracy when using this unit f or
forecasting outdoor weather conditions.
