Hi all readers,

My sailing club have had installed for quite a while a Davis Vantage
Pro Wireless system with wireless repeater. It now has a problem
which I hope someone in this newsgroup will be able to provide a
pointer to a way of resolving.

The ISS is sending all the external weather data back to the console
except for wind speed, which is either displayed as O (zero) or
dashes. The console is receiving information as the X reception
indicator in the lower right corner of the display is flashing.

This problem has occurred in the past intermittently but has
previously 'sorted' its self out!

The ISS & the wireless repeater are using the Davis solar panels.
Which reminds me of another problem during cold weather, i.e. when the
temperature drops below 5C; the ISS stops transmitting. It appears as
a sharp cut-off even if there is good sunshine. Does the battery have
a temperature dependency?

Any pointers to solutions to the above issues will be most gratefully
received.

Kind regards,
Huw

Sounds like your VP may be one of the original ones. There was a batch
in which some systems had problems with a prematurely ageing wind
speed switch, which would give symptoms similar to those you describe.
It simply needs a replacement switch fitted, though this is a service
job.

The ISS transmission is not usually at all temperature sensitive -
it's in regular use by people in locations with severe winters and
typically carries on regardless of the outside temperature even at eg
-30C. But it does sound like you have a problem with your particular
example, which needs troubleshooting in more detail.

Suggest that you get back in touch with your supplier for support - I
don't think it was us from a quick check of your name/email address,
but if I'm wrong do email us please on .

The Vantage ISS did have a problem with the reed switch on the windspeed.
Mine was replaced under warranty.
There are two batteries on the ISS, one that you buy and is not rechargeable
and a rechargeable one on the circuit board that is charged by the solar
panel. It should work below 5C, I have never had a problem down to -8C
(lowest I have got so far)

However the ISS has more of a problem, after two years it failed and after
inspecting it I found the circuit board had corroded in places. Davis wanted
to charge me for an upgrade to sort the problem out. I on the other had am
not prepared to pay for there poor design and am currently taking advice on
taking the UK agent to court for "goods not fit for the purpose"
Check the ISS Circuit board for problems, corrosion especially round the DIP
Switch for changing channels and the edges.

John,

Thanks for the prompt posting, the information is much appreciated.
With replies like this it is a shame that we did not buy from your
company.

Perhaps it is your wireless repeater that is faulty rather than the ISS with
the temperature cut off. My system seems to work perfectly at low
temperatures. I am experiencing the same wind sensor problem very
intermittently so eventually the switch will need to be replaced. Ths ISS
circuit board looks fine - I have just replaced the battery after 30 months
and found that the old battery was still delivering 3V which is its rated
voltage. Given that the life is stated as two years the performance seems to
be good.

I still have the WM2 weather staion and John has given good advice in the
past on this system.
Take it from me when the time comes to replace and upgrade my system to the
Vantage pro, John Dann is the first stop!!

The battery is a lithium one and is rated to much lower temperatures than 5C
so the problem is elsewhere in your system.

Not sure if this'll help but if the windspeed appears as zero and the
direction as dashes this could be normal as the Vantage Pro will record
zeros and dashes if there is no wind for that particular logging time.
For instance my Vantage Pro recorded dashes and zeros between 12.30 and 9.30
on the 01/09/04 as there was no wind to record.

I guess the easiest way to check would be to observe what the anemometer is
doing in relation to what weatherlink records.
