If the password is correct, the display will show the code that
identifies the first group of parameters and it will be possible to
program the parameters of the appliance in the same way as
described in the previous paragraph.
Password protection is disabled by setting the “PASS” par. to OFF.
2.4 - PROGRAMMING OF THE CUSTOMIZED PARAMETERS
AND THE LEVELS OF PARAMETER PROGRAMMING
From the factory settings of the device, the protection by means of
password acts on all the parameters.
If, after having enabled the Password by means of the “PASS”
parameter, it is wished to make some parameters programmable
without protection while maintaining protection on the others, follow
the procedure below.
Go to programming by entering the Password and select the
parameter it is wished to make programmable without password
protection.
Once the parameter has been selected, if the SET LED is flashing,
it means that the parameter can only be programmed by means of a
password and is hence “protected”.
To modify the visibility of the parameter, press the P key and,
keeping it pressed, press the UP key at the same time.
The SET LED will change its state to indicate the new level of
accessibility of the parameter (on = not protected; flashing =
protected by means of password).
In the event the Password is enabled, and in the case that certain
parameters are “unprotected” when the user accesses the
programming mode, all the parameters configured as “not
protected” will be displayed without any division into groups, with
the
“r.PAS”
par. listed last, by means of which it will be possible to
access the “protected” parameters.

NOTE:
in the event of losing the password, remove the power
supply from the device, press the P key and reconnect the device to
the power while keeping the key pressed for approximately 5 sec.
In this way, access is gained to all the parameters and it will hence
be possible to check and modify the “PASS” parameter.
2.5 - CONFIGURATION OF THE PARAMETERS WITH “A01”
The appliance is equipped with a connector that allows the transfer
of the operating parameters to and from the appliance through a
A01
device, which is fitted with a 5-pole connector.
The A01 device can be used for the serial programming of
appliances that must have the same configuration of the
parameters, or for keeping a copy of the programming of one
appliance which can be transferred rapidly to another.
The same device allows connection via the USB port to a PC with
which, using the appropriate software for configuring devices,
“ASCON TECNOLOGIC UniversalConf”, it is possible to configure
the operating parameters.
To use the A01 device, it is possible to supply power to just the
device or just the appliance.

For further information, refer to the user manual of the A01 device.
2.6 - KEYPAD LOCK
The keypad of the appliance may be completely locked.
This function is useful when the controller is exposed to the public
or, in any case, it is wished to block any command.
To activate the keypad lock, press and hold the UP and DOWN
keys at the same time for 5 sec. when the controller is switched on.
After the 5 sec. have elapsed, the display will read
“LOn”
and all
the functions of the keys will result as being blocked, with the
exception of the display of the Set Point.
If any key is pressed when the keypad is locked, the
“LOn
”
message is shown again to indicate it is locked.
To unlock the keypad, simply press and hold the UP and DOWN
keys at the same time for 5 sec., after which the display will read
“LOF”
and all the functions of the keys will result as being
operational again.
3 - WARNINGS FOR INSTALLATION AND USE

are observed, also after installing the appliance, if necessary using
special filters. In the event that a fault or malfunction of the device
should create hazardous or damaging situations for persons,
property or animals, note that the system must be fitted with
additional electromechanical devices designed to guarantee safety.
3.2 - MECHANICAL INSTALLATION
The appliance is housed in a container measuring 78 x 35 mm, and
