Step
2:
Allow
the
heater
to
continue
to
run
until
your
thermometer
reads
your
desired
temperature
for
your
greenhouse.
For
example,
figure
3
shows
that
the
heater
has
now
raised
the
temperature
to
5C.
Figure

Step
3.
Now
the
greenhouse
is
at
your
desired
temperature,
slowly
turn
the
thermostat
dial
(right
hand
dial)
back
down
until
it
‘clicks’.
Once
this
has
clicked,
let
go
and
your
heater
is
now
set
at
to
turn
on
and
off
at
this
temperature.
Figure
4
shows
the
dials
now
in
the
set
position
to
keep
a
greenhouse
at
around
5C.
Please
note
that
the
position
of
the
dial
will
vary
from
situation
to
situation
and
that
the
heater
has
a
temperature
tolerance
of
+/
‐
2C.
