The manual test mode allows the installer to energize the G
fan relay , Table 1, Step 70, and then advance to Step 72 to
energize the Y compressor output with the fan still operating.
It is recommended that this method be used to prevent
damage to the compressor.
The Manual test mode will time out and return to normal
operation after 1 minute from the last key press.
