Settings mode :
• Switch regulator on.
The upper display must display the
temperature measured.
The lower display indicates the set
value saved.
To access the settings mode:
• Simultaneously press the o and q
keys.
The following display will appear :
0
ULoc
The regulator will ask for the password
(ULoc) to gain access to the settings
mode :
16
Definition
• Use the o or p keys to increase or
decrease the upper display value.
Default value for accessing the
settings mode : 10.
• Once the desired value is displayed,
press the q key to validate your choice.
If the value given is incorrect, the
regulator will return to the start display.
If the value given is correct, the
regulator will display the first parameter
(called Filt) contained in the settings
mode.
To modify parameters in the settings
mode :
• Use the q key to shift to the following
parameter.
• When you reach the desired parameter,
use the o or p keys to increase or
decrease the value of the parameter.
• Press the n key to save the value
selected.

Function
This reduces the influence of parasites
on the measurement.
Do not touch it since the quality of the
regulation can be adversely affected.
Used to modify the display of the
measured temperature value.
Increase this value in case of low inertia
load.
Reduce this value in case of low inertia
load.
Caution: too high a value makes the
system unstable. Increase this value in
case of low inertia load.
Defines the type of display.
Setting the limiter :
This is done using parameters d_A1
and d_A2.
Parameter d_A2 allows the hysteresis
to be set (and thus the value for which
the limiter will shut down the burner).
Parameter d_A1 relates to the threshold
for re-engaging the burner following
shut-down caused by the limiter.
For example : If d_A1 = 5, d_A2 = 0 and
SP = 60, then the limiter will engage for
a temperature of 65°C.
The burner will restart when the
temperature falls back down to 60°C.
Remark :
Do not adjust d_A2 < 0.
To quit the settings mode :
• Scroll through the parameters until
you have the same display there was
at start-up (with the temperature
measurement and the set value).
• Then, press the o and q keys
simultaneously to quit the settings
mode and return to the initial display.
