All compressors
are turned off.
All fans are
turned on.
Automatically (if the number of activations is
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:
a. hold pressed the Restart (DOWN) key for
3 seconds or
b. turn off and on the instrument.
- Compressors and fans restarts working
according to the working algorithm.

P1 probe
failure alarm
Probe failure or
out of range.
The
compressors
are activated
according to the
SPr or PoPr
parameters.
Automatically as soon as the probe restarts
working.
P2
P2 probe
failure alarm
Probe failure or
out of range.
The fans are
activated
according to the
FPr parameters.
