3) Once the system has been reset and you
have a temperature reading from the
sensor, temporarily place the remote
temperature sensor in the previous
location.
Note: If there is an outdoor temperature
displayed when the two units are close
together there was either too much distance
between the two units previously or some
type of interference that was causing poor
reception.
4) If after 15 minutes the temperature is not
displayed you will need to choose
another location for placement of the
temperature sensor.
5) The best way of doing this is to move the
sensor 10 feet closer to the indoor
temperature station.
6) After moving the remote temperature
sensor please wait 15 minutes to give the
indoor temperature station time to re-
acquire the signal.
