I have an older Heathkit Weather Station with LED displays (ID-4001) but when I connected a ribbon cable to the data port it made a very large amount of radio interference just by being connected. Maybe the later model with an LCD display and RS-232 interface solved that problem.

". . . . The atmosphere and the earth are part of the same system and rotate together, so if everything was static there would be no friction between the atmosphere and the surface of the Earth.However the atmosphere is a fluid and there is unequal heating between the equator and the poles. The unequal heating causes air density and pressure differences, and the atmosphere develops a circulation. Because the Earth is a rotating sphere the motion of these circulations are deflected to preserve angular momentum. The resulting pattern of atmospheric circulation becomes quite complicated.In the simple case of a non rotating Earth air would rise at the equator and descend at the poles, and at the surface of the Earth there would be a pole to equator ward return flow, that is a northerly wind in the northern hemisphere and a southerly in the southern. This would make a single "cell" of circulation equator to pole in both hemispheres.However as the Earth is rotating, rather than one circulation cell, we have three. The full hemisphere cell mentioned above reaches only to about 30° latitude and is called the Hadley cell (Wiki). The rotation of the Earth affects the cell by deflecting the surface return flow to the west in both hemispheres. These are the NE trades of the northern hemisphere and the SE trades of the southern hemisphere.
The other two circulation cells are the Ferrel (Wiki) and the Polar cell (Wiki). The Ferrel Cell runs in the opposite sense to the direct thermally driven Hadley cell, so the surface winds run the opposite way as well, and are deflected in the opposite way. So in the northern hemisphere in the mid-latitudes the average/predominant wind would be a SW wind. However the Ferrel circulation is much more complicated than this simple picture suggests, and there are flows both north and south, though both are generally from the west."

|There was a problem getting the indoor unit
to synchronize with the new outdoor unit.
The solution is to remove all the batteries and let both units sit for at least 10 minutes, the:
1) install 4 AA batteries in the indoor unit and then press and hold RESET for a few seconds.
2) install a charged AAA battery in the outdoor unit and press and hold RESET for a few seconds.
You can see in photo at left that the indoor unit is showing the temp and humidity of Channel 1 (the remote).
Now to mount the remote outside where it will get some Sun.
PS the THGR122NX Thermo - Hygro Sensor does NOT work with this weather station.
