4.5 Parameter management
4.5.1 Temperature setting (see fi g.1)
1. 1. Turn the main swicth (QS) to “ON” and wait for the temperature
visualization.
2. Press buttons “P3” and “P5” together, to enter into “dIrE” (D)
parameters.
3. Press button “P4” to select “SEt” parameter, press the button
“P5” to con rm.
4. Change the value, using the up and down arrow buttons “P3” and
“P4”, then press button “P5” to con rm.
6. Press the button “P3” to return on “dIrE” parameter.
7. Press the button “P5” to exit.
4.5.2 Differential setting (see fi g.1)
1. Turn the main swicth (QS) to “ON” and wait for the temperature
visualization.
2. Press buttons “P3” e “P5” together, to enter into “dIrE” (D)
parameters.
3. Press button two times “P4” to select “diF” parameter, press the
button “P5” to con rm.
4. Change the value, using the up and down arrow buttons “P3” and
“P4”, then press button “P5” to con rm.
6. Press the button two times “P3” to return on “dIrE” parameter.
7. Press the button “P5” to exit.
4.5.3 Visualization sensors B1,B2...
“B1” is the “set” sensor of the macchine.
1. Start the chiller.
2. Press the button “P4” to visualize the temperature of the next sen-
sor.
3. Press the button “P5” to visualize the sensors “b01” ..“b02”....
It is recommended to leave on the display the B1 “set” sensor.
