warning will occur. NOTE: If this warning is reset while
the conditions for running the dryer exist, the dryer can
restart. Also, the dryer can restart if the evaporator
value rises to 709 (about 5 C). However, the warning
will still be displayed.

Dryer High Pressure
Xe Software Logic for R & RS machines:
On compressors with the integrated dryer, this will
occur if the dryer high-pressure switch opens while the
dryer is running. This is a dryer fault. If this happens,
the compressor will continue to run, but the dryer will
stop. The contact must be open for at least 3 seconds
before the warning will occur.
