Password Management 4.2.1
The program has 3 different password levels:
1. Advanced user (maintenance): read only access to all
parameters. Default password: 0000.
2. Service: read access to all parameters with the ability to edit
some of them (for more information on the parameters that
can be changed, see the parameters table). Default
password: 0001.
3. Manufacturer: read/write access to all parameters. Default
password: 0002.
In the parameters screen, the access needed to edit the
parameters is shown, always with the same codes. An example
follows.
Once the password is entered it will be maintained for 5 minutes
from the last time a key was pressed and then the password will
need to be re-entered in order to access the parameters of the
advanced functions. In the Log-Out menu, the password can be
force entered without waiting 5 minutes.

Scheduler management 4.3.2
thTune allows to configure the scheduler after pushing CLOCK
button for 2s. The data are stored in the thTune, so when passing
from a time band (hh:mm) to another one the display is proposing
as starting time the hour and minute following the previous one
(hh:mm+1). The th-Tune is checking the consistency of the time
bands.
After the push of “ENCODER” terminal displays “Sel days”.
Rotating “ENCODER” is possible to select a group of days or a
single day:
• “7 days” (mon, tue, wed, thu, fri, sat, sun)
• “5 days” (mon, tue, wed, thu, fri)
• “2 days” (sat, sun)
• “Day by day”
It’s possible to select up to 6 time bands for each day.
