5.3. Display Functions
As well as the temperature value display during normal functioning, the display also
shows the value of the main setpoint and the configuration parameter values, as
well as the codes of the latter and possible error messages.
5.1 LED Indications
DP1 blinking: indicates that the controller is in either the parameter programming
mode or that the main setpoint is being set.
•
DP1 ON: indicates that the compressor output is activated (all models).
•
DP2 ON: indicates that the defrost output is activated (Icon 132S & SR).
•
DP3 ON: indicates that the fan output is activated (Icon 132S & SR).
5.4. Display of Main Setpoint
When SET key is depressed once, the display will show the main setpoint for 15
seconds.
5.5. Display of the Defrost Termination Probe Temperature
When keeping the UP key depressed, the defrost termination temperature, detected
by the defrost termination probe, will be shown on the display.
5.6. Changing the Main Setpoint
1. Depress the SET key (the display will show the current main setpoint value;
DP1 – compressor LED – will start to blink).
2. Change the main setpoint value shown on the display by either using the UP
or the DOWN key (the change must be made within 15 seconds after the SET
key was depressed otherwise the controller will switch back to the normal
operating mode and shows the running temperature). The main setpoint
cannot be programmed outside the limit values fixed through parameters d3
and d4. (see Table 2 in Section 6 for d3, d4 parameters)
3. Confirm the newly set value by depressing the SET key (the key must be
depressed within 10 seconds from completion of the previous operation,
otherwise the controller will switch back to the normal operating mode and
show the running temperature without modifying the main setpoint. When the
newly fixed main set point value blinks for 2 seconds, this means that the
acceptance and storage of this new data is confirmed).
5.7. Changing The Configuration Parameters
1. Depress the SET key for 10 seconds, (the display will show the code of the
first parameter and, after two seconds, its value; DP 1 will start to blink);
2. Modify the displayed value of the first parameter using the UP or DOWN keys
the modification must be made within 15 seconds after the SET key was
released otherwise the controller will switch back to the normal operating
mode and show the running temperature).
3. Confirm the newly set value by depressing the SET key (the key must be
depressed within 10 seconds from completion of the previous operation,
otherwise the controller will switch back to the normal operating mode and
show the running temperature without modifying the parameter; when the
newly set value blinks for 2 seconds this means that the acceptance and
storage of this new data is confirmed. After the new value is stored the
controller will display the second parameter code and after 2 seconds the
related value).
4. Modify the displayed value of the second parameter and store the new data by
repeating the procedure described in the two previous points. Proceed in this
manner with all the other parameters (once the last parameter value has been
stored, the display will again show the code of the first parameter and after 2
seconds its related value. After 15 seconds the controller will switch back to
the normal operating mode and show the running temperature).
