10.1 Test and Fault
Recall Modes
10.1.1 Test Mode (Test Button on
the TSODC)
• Enter TEST mode by pressing the UP button with an insu-
lated probe for five (5) seconds and release.
• The TEST mode causes the following:
1) Resets the TSODC from any active protection
lockout mode.
2) Reset the 4-minute anti-short cycle timer.
3) Energizes the unit without a command for unit
operation.
• If the 4-minute anti-short cycle timer or 30 second minimum
run time is active (a flashing "c" or "C" is displayed on the
dual 7-segment LEDs) and a command for unit operation is
present, TEST mode causes:
1) A "c" to display momentarily on the dual 7-segment
display.
2) The compressor will start and the outdoor fan will
operate.
3) The display will change to a steady "c" or "C" to show
the current command for unit operation.
NOTE:
If a command for unit operation is present
at the end of TEST mode will cause the unit to continue to
operate.
• If no command for unit operation is present, TEST mode
causes the following:
1) A steady "c" appears on the dual 7-segments LEDs.
2) The compressor will start.
3) The compressor will turn off after 5-seconds.
NOTE: Entering TEST mode without a command for unit
operation will cause the compressor to run 5-seconds.
