Automatically (if the number of activation are
less than PEn in the PEi time) when the input is
disable.
- Compressors and fans restart working
according to the working algorithm.
Manually (if PEn activation happened in the PEi
time)
When the input is disable:
- hold pressed the Restart(DOWN) key for
