switch input of
circuit 1 (2)
enabled
All compressors of
the circuit 1 (2) are
turned off. Fans
unchanged.
Automatically (if the number of activation are
less than PEn in the PEi time) when the input is
disable.
- The compressors restarts working
according to the working algorithm.
Manually (if PEn activation happened in the PEi
time)
When the input is disable:
a. hold pressed the Restart(DOWN)key for 3s
or
b. turn off and on the instrument..
- The compressors restarts working
according to the working algorithm.

are turned off.
- All fans are
turned on.
Automatically (if the number of activation are
less than PnF in the PiF time) when the input is
disable.
- Compressors and fans restart working
according to the working algorithm.
Manually (if PnF activation happened in the PiF
time)
When the input is disable:
- hold pressed the Restart(DOWN) key for
3s or
- turn off and on the instrument.
Compressors and fans restarts working according
to the working algorithm.
