pressing of button P1.
The (OFF) status is signalled by LED L1 switching on.
9.6.2 OPERATING MODES
MANUAL
With LED L2 (MAN) lit, the fan works at the set speed regardless of
the temperature read by the probe.
AUTOMATIC
With LED L3 (AUTO) lit, the fan activates at the set speed if the tem-
perature read by the probe is higher than the SET parameter setting.
PROPORTIONAL
With LED L4 (PROP) lit, the fan activates at the speed calculated in
the SET – (SET + DEL) parameter range if the temperature read by the
probe is greater than SET parameter setting.
9.6.3 FUNCTIONS
STAND-BY function
The function is active (parameter Stb=1).
With the device switched off (OFF), if the temperature read by the
temperature probe exceeds the value of parameter TSI, the device
automatically switches to the ON status (ON).
SAFETY function
The function is active (parameter SIC=1).
If the temperature exceeds the value of parameter TSI, with the fan
off and MANUAL mode (MAN) active, the device switches to PRO-
PORTIONAL mode (PROP) with a 10-second initial delay.
FAN SAFETY function
The function is not active (parameter SAF=0).
With the function active, if the temperature exceeds the value of pa-
rameter tSA, the fan is switched off (OFF).
ALARM function
The function is active (parameter Enb=1).
If the temperature exceeds the value of parameter TAL:
- the buzzer sounds which can be deactivated for 5 minutes by press-
ing any button
- after this time, if the alarm condition persists, the buzzer sounds
again.
