TIME ZONE
0253 0 Zone: Binary (2's comp) nibble 0 [Range F4 (-12) to 0C (+12) hours from UTC]
0254 0 Zone: Binary (2's comp) nibble 1 (high bit is also sign for BCD value)
0255 0 Zone: BCD 1s
0256 0 Zone: BCD 10s

Note: Must set both binary and BCD values to change zone. Local time is recalculated at the next minute interval

Note: The offset is the Standard time offset of the time zone; it does not change when daylight time or summer time goes into effect. (There should be a separate bit somewhere in the map that indicates whether daylight time is in effect)

RAIN COUNTING AREA
The station counts rainfall in "impulses" and keeps a number of rolling counters as 3 nibble binary values. As the station proceeds through various calculations these counters progressively end up with the same value.
*Rainfall per impulse* calibration of the rain-guage. Default 0.518mm/impulse
*Remote station raincount* last reading from the remote rain sensor. Resets to zero when remote batteries changed.
*Remote station raincount 2?* Seems to always be the same as the above value, not sure why the station would need that.
*Last rainfall total counter* previous counter value used to increment Rain Total (04D2) Use as basis to interpret history data
*Last 24HR counter* previous counter value used to increment rainfall in the last hour
*Last 1HR counter* previous counter value used to increment rainfall in the last 4 minutes

Last 24hr rainfall is tracked as 24 * 2 binary nibbles representing the number of impulses that occurred x hours ago. The most recent one is updated frequently with the latest information. On the hour, the values are rolled down and the 24HR total (0497) recalculated as the sum of these values.
Last 1hr rainfall is tracked as 15 * 2 binary nibbles representing the number of impulses that occurred in each 4 minutes of the last hour. The most recent one is updated frequently with the latest information. Every 4 minutes the values are rolled down and the 1HR total (04B4) recalculated as the sum of these values.

HISTORY
4,3,2,1,0: Indoor and outdoor temperature
Tindoor = (value % 1000)/10 - 30 [C]
Toutdoor = (value - (value % 1000))/10000 - 30 [C]
Where % is the modulus operator.

9,8,7,6,5: Absolute Air Pressure and Indoor Humidity.
Pressure= 1000 + (value % 10000)/10. If pressure is greater than or equal to 1500 then you subtract 1000.
Indoor humidity =(value-(value % 10000))/10000

11,10: Outdoor Humidity in plain human readable BCD

14,13,12: Rain. (RAINCOUNTn)
The value is binary and steps by rainfall/impulse (from 0437) mm/step. Every period the current 12-bit rain count value (from 043A) is stored as history data.

Call the value for a specific history record 'RAINCOUNTn'.
The first time a program is started without a history data file but connected to the station, the program should fetch the total rain value from addresses 04D7-04D2. We can call this RAINref.
Then save the "Last rainfall total counter" value from 0440. Call this RAINCOUNTref. The program always saves just ONE value when it starts and this becomes a reference value for the entire time the program is running. From then on each new history record (past or future for the run of the program) is fetched by the program and the total rain for a single history record is calculated using RAINCOUNTn.
RAINtotal = RAINref + (RAINCOUNTn - RAINCOUNTref)* rainfall/impulse
If the total rainfall has been reset, or the remote sensor is reset (eg battery change) then the historical counter values will be out of sync and the program will need to handle accordingly.
17-16-15: Windspeed = value in binary / 10 [m/s]

18: Wind direction = value * 22.5 degrees. North is 0 and degrees are clockwise on the circle.
