Description of software settings:
° F or ° C
This determines whether Fahrenheit or Celsius is used. When changing between these two you will notice
any temperature range will also change but any temperature entries made or uploaded from the board will
not change, you must make sure the entries are within the new range before writing the data back to the
board.
Special notes:
Temperature Conversions
Under the "Help" menu there are two conversion selections, ° F to ° C and ° C to ° F. When you select one
of these the conversion window opens up. Enter the temperature you desire to convert in the top box. Click
on the "Convert" button or press the "Enter" key to see the result in the bottom box. You can enter a
decimal number to convert but the result will be rounded to a whole number. Example: If converting ° F to
° C, and 45.6° F is entered, the result will be 8° C (actual value is 7.555555...). Because this window will
stay displayed, until you click on the "Exit" button or press the "Esc" key, you can move back and forth
between the conversion window and the main window.
Outdoor (OT) and Buffer Tank (BT) Offsets
Enter an offset to be added to or subtracted from the temperature read from the sensor. Example: To enter a
5 degree lower offset, enter: - 5.
