Q:
Outdoor temperature shows dashes.
A:
Dashes means you have lost connection between the display and the
outdoor sensor. Batteries are the most common problem.
A:
Distance/Resistance can cause loss of sensor signal. If possible avoid
having more than 1 wall, window, tree etc., between the display and the
sensor. UV coated windows may actually reflect the signal. Stucco walls
will absorb the signal.
A:
You may find it helpful to orient the Display 90 degrees towards the
Thermohygro sensor for better reception.
A:
Please, remove the batteries from the Thermohygro sensor for 2 minutes.
Replace the batteries in the Thermohygro sensor and after 5
minutes press and hold the UP ARROW on the display until it beeps. Wait
10 minutes. If you do not receive a reading from all your sensors please
try the factory reset below.
NOTE: It can take several tries to get the Wind and the Rain to connect.
Please install batteries in the Rain and Thermohygro sensors and key the
Wind sensor and allow them to operate in line-of sight of each other
for 2 minutes before powering up the display.
A:
Complete a RESTART. It is not necessary to bring the sensors in the
house unless they have never worked.
FACTORY RESTART:
A Factory Reset will erase the connection between the Display and the
Thermo-hygro sensor and allow a fresh connection to be re-established. It
is recommended to have the display and all sensors 5-10 feet apart for
this restart.
 ENTER PROGRAM MENU: Press and hold the SET button until
you enter the program menu. Press and release the SET button
until you see 'rES oFF' flashing.
 FACTORY RESET ON: Use the ▲UP ARROW key or ▼DOWN
ARROW key to turn rES on.
 CONFIRM & COUNTDOWN: Press the SET key to confirm and
a countdown timer will begin counting down from 127. When
the timer displays dOnE, you must remove the batteries from
the display for 10 minutes.
