7. OPTIONAL CONFIGURATIONS
7.1 Other confi guration parameters
The other confi guration parameters that need to be set when
commissioning the controller concern :
• the measurement stability of analogue probes;
• the selection of the user terminal and/or remote display;
• the enabling of the keypad, remote control and buzzer (accessory);
• the standard display on the user terminal and the remote display;
• the display of messages / alarms on the remote display.
• the display in °C / °F and the decimal point;
• the locking of the buttons on the user terminal;
• the availability of the RTC (real time clock);

Tab. 7.a
Defi nes the coeffi cient used to stabilise the temperature measurement.
Low values assigned to this parameter mean a prompt response of
the probe to variations in temperature; the reading however becomes
mostly sensitive to disturbance. High values slow down the response but
guarantee greater immunity to disturbance, that is, a more stable, more
precise and fi ltered reading.

This parameter used to select if the user terminal and/or the remote
display are optional, and are automatically recognised when fi tted. If the
required device is confi gured as optional, no alarm is generated on the
supervisor when absent.
H2: Disable keypad and remote control functions
Some functions relating to the use of the keypad can be disabled, for
example setting the parameters and the set point if the controller is
exposed to the public.

When the set point and type F parameter setting functions are inhibited,
neither the set point nor the type F parameters can be changed, while
their values can still be displayed. The type C parameters, on the other
hand, being password protected, can also be set from the keypad,
following the procedure described previously. With the remote control
disabled, only the values of the parameters can be displayed, but they
cannot be modifi ed; in addition, the mute, defrost, continuous cycle, and
aux functions are disabled.
Note: If H2=2 or H2=3 is set on the remote control, this is
immediately disabled when pressing ESC. To re-enable the remote
control, set ‘H2’=0 or ‘H2’=1 from the keypad on the user terminal, on the
supervisor or in VPM.
/t1, /t2, /t: Display on user terminal and on remote display
Parameters /t1 and /t2 select the variable shown on the display during
normal operation. In the event of alarms, /t enables the display of alarms
on the remote display. For example, during defrost if /t=0 and d6 = 0, the
display does not show dEF alternating with the temperature set for /t2,
while when /t=1 the display shows dEF alternating with the temperature
set for /t2.
