• The counting is reset after one of the follow-
ing events: defrosting cycle carried out, power 
failure, operating mode change.  

Power failure 
In case of power failure, when power is 
restored, the control returns to the status 
prior to the power failure. If defrosting is in 
progress, the procedure is cancelled. All tim-
ings are cancelled and initialised again. 

MANAGEMENT OF SUMMER/WINTER MODE 
CHANGE
The change can take place:
• from digital input (if enabled)
- control on the machine: the icons summer/
winter blink
- remote panel: the icons summer/winter are 
fixed
• from keyboard (if the digital input is disa-
bled)
- control on the machine: the icons summer/
winter are fixed
- remote panel: the icons summer/winter 
blink when a mode change is performed, they 
remain fixed after 10 seconds
• from supervision

DELIVERY/RECOVERY FAN CONTROL
The fans are off only if:
- a fans block alarm is present
- the unit is OFF

SUMMER NIGHT FUNCTION
The function is enabled via parameter or time 
bands and it is enabled only if the free cool-
ing conditions are met. The night function 
has higher priority compared to the possible 
stand-by mode.
In case the above conditions are present:
- the free cooling function is activated with 
null equivalent band (full open or closed 
dampers)
- if the opening of the damper was requested, 
the fans are activated
- all other functions are disabled
The function can be disabled in two ways:
- by time-out if the time bands are disabled;
- by manual mode/function change, OFF, time 
bands disabling.

TIME BANDS

Profiles configuration

The operating modes for each profile are defined via 
the Prof mask in the prg menu
The profile will be identified as “tE0n x” where n is the 
number of the day of the week and x is the set profile.

tE01 

Monday profile

tE02 

Tuesday profile

tE03 

Wednesday profile

tE04 

Thursday profile

tE05 

Friday profile

tE06 

Saturday profile

tE07 

Sunday profile

Time bands management

To activate/deactivate the time bands, it is possi-
ble to press for a few seconds the UP arrow key.
The controller on the machine will display the 
clock icon while the display of the remote con-
trol panel will show the F1 icon symbol and the 
corresponding active profile. 
The time bands include 5 profiles (defined via 
the Prof mask of the prg menu):

- profiles 1, 2, 3 with four events each
Each EVENT consists of a start time (in the 
format HH:MM) and an operating mode (0 
= OFF, 1 = ECO, 2= COMFORT, 3 = NIGHT). 
- Profile 4: only Comfort
- Profile 5: only Off

From the DayP, the scheduler can be activated 
with the parameter tE00. Then each day of the 
week can only have one of the 5 possible pro-
files, by setting the parameters tE01….tE07 from 
1 to 5 for each day of the week.
