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 confi rm.
4. Change the value, using the up and down arrow buttons “ P3 ” and
“ P4 ”, then press button “ P5 ” to confi 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 confi rm.
4. Change the value, using the up and down arrow buttons “ P3 ” and
“ P4 ”, then press button “ P5 ” to confi 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
” ..“
