If no elements are present,
“NO ALARMS”
will be displayed. Otherwise, the following screen will be displayed:
To view the next element, press ENTER at “Next>>”. Repeat this procedure to scroll through all the elements of the
history until you arrive at the first element. To exit the history, press ESC or wait for 60 seconds without any activity.
This level is not protected by a password.
The code for each alarm is the code shown in the table of alarms (see Dépannage). The history can contain 100 events.
With parameter
PH18 Delete alarm history
, you can delete the history of all the stored elements; set the parameter
to YES (1) and wait for two seconds until the default value NO (0) is displayed again.
Note.
Storage of a subsequent event in the history, beyond the maximum permissible number of events (100), deletes
the first event inserted and so on for other events.

CONFIGURATION OF SPECIFIC FUNCTIONS
7.1
SUPPLY AND RETURN FANS
The programme manages two fans; the supply fan and the return fan. For both fans, provision is made for an ON/OFF
setting or setting via a frequency converter. The operating speed is the same for both fans, except when operating in
“Recovery unit frost protection and flow offset“
.
The setting differs according to parameter
PF01
, which distinguishes manual setting from automatic setting with a
presence sensor:
•
PF01
=0 Manual setting
•
PF01
=1 Automatic setting without presence sensor
•
PF01
=2 Automatic setting with presence sensor
•
PF01
=3 Automatic setting via DCV sensor
In ON/OFF control (parameter
PG10=0
), each fan is controlled with 3 speeds (V1, V2, V3), which are controlled via a
dedicated relay.
When controlled with a converter (parameter
PG10=1
), the three speeds are determined by a frequency value. Using
parameters
PF21
,
PF22
and
PF23
, you can define the values of the frequency converter for each speed.
7.1.1.1
Manual setting
The fans work at the speed configured via parameter
PF02
.
7.1.1.2
Automatic setting without presence sensor
The clock menu enables automatic setting without presence detector
