The bar graph indicates the air pressure history trend over the last 12 hours in 5 intervals: 0h, -
3h, -6h, -9h and -
12h. The “0h” represents the current full hour air pressure recording. If the bars
are rising it means that the weather is getting better due to the increase of air pressure. If the bars
go down, it means the air pressure has dropped and the weather is expected to get worse from
the present time “0h“.
The air pressure is displayed numerically in relative or absolute values.
Press and release the SET button to switch from relative (rel) to absolute (abs).
POSITIONING
WEATHER STATION:
Table stand:
The weather station comes complete with a foldout stand that gives the option of
table standing or wall mounting.
To wall mount:
1. Fix a screw into the desired wall, leaving the head extended out by about
0.2” (5mm).
2. Using the weather station hanging hole, carefully hang it onto the screw.
Note: Always ensures that the unit locks onto the screw head before releasing.
POSITIONING THE THERMOHYGRO TRANSMITTER:
To wall mount:
1. Secure the bracket onto a desired wall using the screws and plastic anchors.
2. Clip the transmitter onto the bracket.
Note: Before permanently fixing the transmitter wall base, place all units in the
desired locations to check that the outdoor temperature reading is receivable. In
event that the signal is not received, relocate the units or move them slightly as this
may help the signal reception.
Place the sensor outside protected from direct sun and standing rain or snow. Under and eave or
deck rail on the north side work well.
Note: The reception distance of the thermohygro transmitter may be affected by the temperature.
At cold temperatures the transmitting distance may be decreased. Please bear this in mind when
placing the transmitter.
