TECHNICAL SPECIFICATIONS
SAFETY WARNINGS
1) The instrument should be installed by qualified personnel
2) Read the instructions in this manual carefully
3) Carefully follow the instruction diagrams to install the device
4) Before gaining access to the connector terminals, make sure the conductors
to be connected to the instrument or already connected are not powered
5) Make sure the electric panel in which the device is inserted will prevent
access to the terminals after installation
6) Do not supply power to the device if any part of it is damaged
The instrument must be installed and activated in compliance with current
electric systems standards.
7)
The connection cables should be able to resist the maximum operating
temperature in the form of the maximum ambient temperature + 20 °C
8)
The instruments guarantee main insulation between the low voltage parts
(250 V) and the extremely low voltage parts
10)
9)
Any outside switches connected to the control panel should guarantee
a minimum insulation of 250 V AC at operating temperature, or should be
protected by equivalent insulation
IMPORTANT: In order to avoid malfunctions, the differential of intervention
(DF1 or DF2 parameter) should not be set above 30 °C.

User Manual Digital Heat Regulators
PWM operation (in proportion to time)
,This is a neutral zone type of operation in which the relays are activated
periodically in impulse mode
(the interval can be set, see the
output menu).
The PWM procedure modulates
the power in accordance with the
position occupied by the
measurement within the
differential (the further we move
away from the set point, the more
the power increases).
Important: we advise against using this method to drive compressors,
due to the very close distance between start-up and shutdown.
Direct operating mode [PRO=0]
,In this mode, all the outputs
operate in direct. The values
of set point 1 [ST1] and
differential 1 [DF1] have
to be set. Hysteresis is to the
right of the set point. If both
outputs are used, the
hysteresis for each output is
equivalent to half the
differential. In this case,
output 1 will be activated when the measurement controlled reaches the value
[ST1]+[DF1]/2 [SP], and remains active until the temperature drops below the value of ,
while output 2 is activated by temperature values of and remains active [SP]+[DF1]
until the temperature drops below the value of .[SP]+[DF1]/2
Reverse operating mode [PRO=1]
,In this mode, all the outputs operate in reverse.
The set point 1 [ST1] and differential 1 [DF1] values have to be set.
Hysteresis is to the left of the
set point. If both outputs are
used, the hysteresis for each
output is equivalent to half the
differential. In this case,
output 1 will be activated
when the measurement
controlled reaches the value
[ST1]-[DF1]/2, and remains
active until the temperature
exceeds the value of [SP], while output 2 will be activated when the temperature
reaches the values of [SP]-[DF1] and remains active until the temperature
exceeds the value of [SP]-[DF1]/2.

Reverse operating mode with set point and differential switching
from digital input. [PRO=8]
*In this mode, both outputs operate in reverse, with set point 1/differential 1 or set
point 2/differential 2, depending on the status of the digital input.
More precisely, with set point 1/differential 1 if the digital input is open and set
point 2/differential 2 if closed. The operating modes are the same as mode 1.
It is necessary to set both values of the set points [ST1] [ST2]and and
differentials and .[DF1] [DF2]
Operating mode with channels 1 and 2 in reverse with set point 1
and differential. 1 and direct with set point 2 and differential 2
[PRO=9] respectively.
*In this mode, output 1 operates in reverse and output 2 in direct. It is necessary
to set the values of set point 1 [ST1] and differential 1 [DF1] for output 1,
and set point 2 [ST2] and differential 2 for output 2.[DF2]
The operating modes are the same as modes 0 and 1.
If there is a single output, this will operate in reverse.
Alarm operating mode [PRO=10]
*In this mode, output 1 operates in reverse (with neutral zone), and output 2 is
dedicated to the alarm. It is necessary to set the values of set point 1 [ST1],

operation (this also happens if no key is pressed for at least 40 seconds).
Press “OK” to switch between the display of the parameter label and its numerical
value. To modify a parameter:
- from the display of its label or value, press “OK” and hold down for at least
three seconds
- the display will start to flash and will show the parameter value
- use the “up” ( ) “down” ( )and keys to increase or reduce the value
- press “OK” to confirm the parameter and leave the modification (the display
will stop flashing)
Note: if no key is pressed for at least 40 seconds, the instrument leaves
the parameter modification without memorising the changes made.
During the display and modification of the parameters, the instrument
will continue to operate with the previously set parameters.
If “password 1” is enabled (access password to protect the settings entered-see
system menu), when the “OK” key is pressed from normal status the message
“- - - ” will appear. To set the parameters, enter the previously set password
(a number from 0 to 255) with the “up” ( ) “down” ( )and keys and press
“OK” to confirm. If the password is entered correctly, the label of the first menu
will appear. Otherwise, the system will return to normal status.
Advanced programming
Access is gained to advanced programming from normal status by pressing and
holding down the p and q keys for at least 3 seconds.
Note: to reset the default values set in the factory, switch on the instru-
ment while holding down the “OK” key.
These parameters are grouped into eight menus, by type:
1) Regulation [REG](indicated with ): set point, differential, neutral zone
2) Output (indicated with [OUT]): output drive times, PWM cycle time
3) Digital input (indicated with [ING]): function, delay time
4) Alarm (indicated with [ALR]): output status in probe alarm, minimum/maximum
shift, differential, delay time, buzzer enable
5) Display (indicated with [DSP]): set point limits, probe offset, resolution,
measurement unit, measurement filter
6) Sensor [SNS](indicated with ): type of sensor, sensor parameters
7) System [SYS](indicated with ): password, modification enable, operating mode
8) Advanced [ADD](indicated with ): dependence, type, entry, differential/logic
All the parameters inside the menus and their values are listed in the section
that follows.
- Use the “up” ( )to scroll through the eight menus in sequence
- To enter the menu required, press “OK”
Press the “down” ( )key at any time to leave the menu and return to normal

that can be modified by pressing “up” ( ). To display the value of the parameter,
press (press“OK” “OK” a second time to return to the display of the parameter
label).
- To modify the parameter value, hold down “OK” for at least 3 seconds.
- The parameter value will start to flash and it will be possible to increase or
decrease it with the “up” ( ) “down” ( )and keys.
- To confirm the value set, press “OK”.
The parameter will stop flashing and the new value will be displayed.
- It is possible to return to normal operation at any time by pressing “down” ( )
(or if no key is pressed for at least 40 seconds).
Note: if no key is pressed for at least 40 seconds, the instrument leaves
the parameter modification without memorising the changes made.
Note: During the display and modification of the parameters, the
instrument will continue to operate with the previously set parameters.
If “password 2” is enabled (access password for the protection of the settings-see
system menu), when the “up” ( ) “down” ( )and keys are held down
for three seconds from normal status, the message “- - - ” will appear.
To set the parameters, enter the previously set password (a number from 0 to 255)
with the “up” ( ) “down” ( ) “OK”and keys and press to confirm.
If the password is entered correctly, the label of the first menu will appear.
Otherwise, the system will return to normal status.
To simplify the programming of the instruments, the parameters are grouped into
various menus, in the following order:
— [REG] regulation menu
— [OUT] output menu
— [ING] outside input menu
— [ALR] alarm menu
— [DSP] display menu
