When
should
the
sprinklers
turn
on?
The
sprinklers
are
often
turned
on
around
70°F.
This
default
is
a
good
temperature
setting
to
start
with.
Parameter
“P40
sprinkler
low
temp”
controls
when
the
sprinklers
begin
to
cycle.
How
much
water
should
I
spray
on
the
cows
The
idea
of
soakers
is
to
spray
water
onto
the
cow
until
she
is
wet.
You
may
wonder,
how
do
I
know
if
she
is
wet
enough?
It
is
easy
to
determine
this
once
you
have
your
sprinkler
system
installed.
You
get
a
stopwatch
and
watch
as
the
water
is
spraying.
When
she
becomes
saturated
and
the
water
begins
to
run
off,
that
is
the
maximum
wetness
you
can
get.
Record
the
length
of
time
it
took.
You
need
to
make
sure
that
her
udder
is
not
getting
wet.
Refer

and

below
for
the
proper
wetness.
Here
you
can
see
that
the
water
has
not
wetted
the
cow's
udder.
Soaking
the
cow
but
not
her
udder
is
the
goal.
Often
the
time
needed
to
wet
the
cow
is
approximately
30
seconds.
This
varies
considerably
by
nozzle
sizes
and
water
pressure.
The
default
setting
is
30
seconds,
Parameters

P47
allow
you
to
adjust
each
sprinkler
zones
spray
time.
You
can
adjust
the
system
to
spray
more
water
when
it’s
hotter.
However,
proper
wetness
does
not
vary
significantly
by
temperature.
Now
you
know
how
wet
to
make
the
cow.
You
also
know
where
to
adjust
the
spray
time.
