1. Remove all batteries, reinsert into
remote temperature sensor first, then
into the indoor weather station.
2. Place remote temperature sensor closer
to the indoor weather station.
3. Be sure all batteries are fresh.
4. Place remote temperature sensor and
indoor weather station in position so the
straight-line signal is not passing
through more than two or three walls.
Problem: Temperatures do not match if
units are placed next to each other.
Solution:
Each temperature sensor is manufactured to
be accurate to within 1 degree plus or minus
and under normal conditions, so two sensors
could be as much as 2 degrees different.
However, the difference can be exaggerated
further because the sensors are designed for
different working environments. The indoor
sensor is less responsive to ambient air
currents because of the shielding effect of
the display's case. In addition, the case can
act as a heat sink to absorb and store heat
from external sources (i.e. handling of the
