Outdoor Temperature Transmitter
Compatible Outdoor Transmitters
• A TX37U-IT outdoor transmitter comes packaged with this clock.
• The TX37U-IT and TX45U-IT (915MHz) transmitters are compatible with this clock.
Fahrenheit/Celsius
• Use the program menu to select Fahrenheit or Celsius temperature display.
Flashing Outdoor Temperature
• The outdoor Temperature reading will flash when the connection is first lost or
intermittent between the clock and the outdoor transmitter.
• Distance/Resistance is generally the cause of intermittent connection or loss of
connection between the transmitter and the clock.
• Check the position of the clock. Turn the clock 90 degrees towards the outdoor
transmitter for better reception.
• Try the quick connect or factory restart.
• Batteries often resolve the connection issue.
Dashes shown for Outdoor Temperature
• Dashes means the connection is lost between the clock and the outdoor transmitter.
• Batteries often resolve the connection.
• Distance/Resistance can cause loss of connection between the transmitter and the
clock.
• Reorientation of the clock 90 degrees towards the outdoor transmitter may provide
better reception.
• Try the quick connect or factory restart.
Inaccurate Outdoor Temperature Reading
• The outdoor transmitter reads the environment. When mounted in the home it will read
inside temperature.
• When the transmitter reads high during the day but not at night it is a positioning
problem.
• Side-by-side test: Bring the outdoor transmitter in the house and place it next to the
clock for 2 hours.
• Compare indoor and outdoor temperature. The temperatures should be within 4
degrees to be within tolerance. See the section on accuracy for details.
• If the transmitter reads correctly when next to the clock, then try a different location
outside.
• Look for heat sources such as sunlight, door or window frames, or reflected heat.
