the Ice Alarm to sound constantly if the measured reading is close to 39.2
°
F, a hysteresis
function has been implemented for the alarm.
If the current temperature value drops to 39.2
°
F, the ice alarm will be activated (if the alarm
has been enabled).
Since the preset hysteresis is 1.8
°
F. If the temperature rises back to 40.3
°
F and thereafter
again drops to below 39.2°F, the data will be blinking, but no alarm will be activated.
With the pre-set hysteresis of 1.8
°
F, it has to rise back to above 41°F and drop below
39.2
°
F to trigger the alarm again.
Note:
After the alarm is triggered, the alarming icon will still blink when the temp is still
between 39.2 to 41
°
F.
915 MHz RECEPTION
The Weather Station should receive the temperature data within 5 minutes after set-up.
If
the temperature data is not received 5 minutes after setting up (not successfully
continuously, the outdoor display shows “- - -” ), please check the following points:
1.
The distance of the Weather Station or sensor should be at least 5 to 6.5 feet away
from any interfering sources such as computer monitors or TV sets.
2.
Avoid positioning the Weather Station onto or in the immediate proximity of metal
window frames.
